California passed the Alquist-Priolo Earthquake Fault Zoning Act in 1972 to mitigate surface ruptures. Rattling of dishes, windows, doors; glassware and crockery clink and clash. a magnitude 5 earthquake is ten times as intense as a magnitude 4 earthquake. Cracked ground, especially when loose and wet, up to widths of several inches; fissures up to a yard in width ran parallel to canal and stream banks. moved away from the epicenter. IX. We sometimes assign points to a homework assignment to rate how well we did. A December 2004 Indian Ocean earthquake of magnitude 9.19.3 caused tsunamis along the coasts of the Indian Ocean. MTC 17: Hybrid Experimental and Analytical Simulation in Earthquake Engineering Disturbances in ground great and varied, numerous shearing cracks. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "'"`UNIQ--templatestyles-0000000A-QINU`"'Mw" magnitude usually reported for an earthquake). In a normal faulting zone, subsidence is evident from the creation of horsts and grabens, raised or lowered blocks of crust. Italian volcanologist Giuseppe Mercalli formulated his first intensity scale in 1883. Broke numerous windows, furniture to some extent. Even sports teams have different levels to make sure that teams with the same ability play each other. The scale looks at areas surrounding the epicenter and a Acrobat Distiller 5.0 (Windows) 6 How does the Roman numeral numbering system work? The Mercalli Scale The Mercalli scale has 12 divisions, using Roman numerals from I to XII. This scale attempts to quantify the effects on a scale from I (Roman numeral 1), where its not felt, to XII, which is total destruction. Destroyed most masonry and frame structures, also their foundations. Dammed lakes, produced waterfalls, deflected rivers, etc. By using a common rating scale for earthquakes, engineers can predict which earthquakes are going to cause the most violent seismic waves and damage to structures. earthquake. 5 When was the Modified Mercalli intensity scale created? Earth slumps and land slips in soft ground. Earthquake Intensity What controls the shaking you feel? For example: "Rio de Janeiro, The class could even draw one level of the scale at a time together. The earthquake and its impact is measured either by using the Mercalli scale or the Richter Scale. The Mercalli Scale was used earlier than the Richter Scale. By rating earthquakes, engineers can predict which quakes are going to cause the most damage and warn humans about them. Damage considerable to concrete irrigation ditches. Register on XBet. [9] Some seismologists refer to this version the "WoodNeumann scale". Mercalli Scale Simulator | Welcome Bonus! A major parking structure collapsed at the Free K-12 standards-aligned STEM curriculum for educators everywhere. Ejected water in large amounts charged with sand and mud. [13], The basis by which the U.S. Geological Survey (and other agencies) assigns intensities is nominally Wood and Neumann's MM31. USGS image, public domain. [2], The correlation between magnitude and intensity is far from total, depending upon several factors including the depth of the earthquake, terrain, population density, and damage. The north end reaches towards Malad City, Idaho, and the southern-most segment extends to Fayette, Utah. Unstable objects overturned. The Richter scale is more objective, but the Mercalli scale is subjective. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings. Soft ground will cause land slips, and fissures will open. When I wrote my book I expected a San Andreas earthquake scenario to be easy to find with all the Hollywood disaster movies. Mercalli Scale Simulator - Blackjack. Some well-built wooden structures destroyed; most masonry and frame structures destroyed with foundations. The following is an graphic of the Wasatch Fault with its major fault segments along the Wasatch Fault. cracks in the wall but no other structural damage. The intensity is not completely determined by the magnitude. I. This scale, composed of increasing levels of intensity that range from imperceptible shaking to Understand the difference between the Richter Scale and the Mercalli Scale for rating earthquakes (a scale that uses instruments and a scale that uses human observation, respectively). The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. Extreme -- Some well-built wood structures may survive, while most frame and masonry buildings and foundations are destroyed. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann. Numerous intensity scales have been developed over the last several hundred years. The intensity is not completely determined by the magnitude. Thanks for your feedback! Mercalli Scale Find out about the Mercalli scale that measures the intensity of an earthquake rather than its magnitude. As the tsunami passes through shallower water, wave shoaling compresses the wave, making it slower and taller. (That was the Richter magnitude for the Chile earthquake of 1960. Tectonic subsidence may also occur when loose sedi, There are 119 public school buildings at increased risk of "significant earthquake damage" because they are classified as unreinforced masonry construction (URM) in seismic safety screenings. This scale, composed of increasing levels of intensity that range from imperceptible shaking to catastrophic destruction, is designated by Roman numerals. To understand the difference between the intensity scale and the Damage serious to dams, dikes, embankments. Thanks for your feedback! URM buildings are typically older structures. Which is better Mercalli vs Richter scale? out about the discoveries that have been made by scientists using surveys ask people about damage to their homes and other structures When Harry O. Tsunami wave rises high and quick over steep coastline Tsunamis can be caused by vertical displacement of the seabed due to an earthquake. When searching for trusted online casinos, a discerning approach is best. The Richter scale measured the quake as a magnitude 6.7 which seemed low Once house was 3 miles from the epicenter and suffered total Students learn about the types of seismic waves produced by earthquakes and how they move through the Earth. Students also investigate which structural designs are most likely to survive an earthquake. MTC 17: Hybrid Experimental and Analytical Simulation in Earthquake Engineering - Poster Papers The Act prevents the construction of human-occupied buildings on the surface of active faults. Vibration like that due to passing of light, or lightly loaded trucks, or heavy trucks some distance away. The modified Mercalli intensity scale (MM or MMI), developed from Giuseppe Mercallis Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. Dishes, windows, and doors are disturbed; walls make cracking sounds. Cut all necessary paper needed for the class activity. Fall of plaster in small amount. Landslides considerable from river banks and steep slopes. %PDF-1.4 % Note: The Modified Mercalli scale is designed to describe the effects of an earthquake, at a given place, on natural features, on industrial installations and on human beings. How does the Roman numeral numbering system work? Register on Cafe Casino. The ShakeOut The State of California Department of Conservation has a 2008 earthquake scenario that was used for its ShakeOut drill in the event of an earthquake on the San Andreas Fault ( 2008 ShakeOut Scenario ). However, these contents do not necessarily represent the policies of the Department of Education or National Science Foundation, and you should not assume endorsement by the federal government. A good website to visit is: https://www.ngdc.noaa.gov/ngdc.html. scale listed the hardest hit areas as IX showing major structural Rails bent greatly. is used by insurance companies and local planning commissions in urban Note: This simulation does not take into account the topography or water masses in the region and is most accurate for events between 3.5 and 6.0 magnitudes. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Alaska Earthquake The Damage slight in structures (brick) built especially to withstand earthquakes. A pull-apart basin forms when opposing walls of the fault pull apart from each other, resulting in dropped ground. Caused sea-waves ("tidal" waves) of significant magnitude. Buildings are shifted off foundations. Mercalli Scale Simulator 7. Cracked, broke, solid stone walls seriously. live at the epicenter or a thousand miles away the news reports would Fall of walls. With improved engineering technology to predict the size and force of earthquakes, cities and communities have more time to prepare themselves from harm. Tell students to draw a picture having to do with an earthquake or the Mercalli Scale. While there is no cash to win in free games, they still contain the same free spins and bonus rounds found in real money games that keep the gameplay fun. Ground waves may be seen. Well-built structures may receive slight to moderate damage. The intensity Stover, C. W., and Coffman, J. L. (1993). Weak -- Most people indoors will feel the movement, particularly in the upper floors of buildings. www.teachengineering.org/activities/view/cub_natdis_lesson03_activity3, Search curriculum by Common Core standards, Natural Disasters: Earthquakes, Volcanoes, Tornadoes & More. Sand and mud ejected in small amounts. Cracked chimneys to considerable extent, walls to some extent. The damage to structures Mercalli Scale Simulator : Play Now Guns N' Roses. While there are subsidence can occur as the result of different types of tectonic actions, generally tectonic subsidence happens when the vertical movement of ground causes nearby ground to lower in relation to it's previous location. While it's been several weeks since my last post, I wanted to let you know that I have five posts in the works. The scenario projected about 1,800-2,000 deaths, 50-53,000 injuries requiring emergency care, and $191-200 billion in damages. [10] Some seismologists refer to this version the "WoodNeumann scale". Thanks for your feedback! Persons made to move unsteadily. Some heavy furniture is moved; a few instances of fallen. 2002-04-02T08:19:20-06:00 list the earthquake with the same magnitude. This scale is used by insurance companies and local planning commissions in urban areas. Mercalli Scale Simulator | Welcome Bonus! In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. Damage considerable in specially designed structures; well-designed frame structures thrown out of plumb. XII. Source: Wood, H.O., and F. Neumann, 1931. Creaking of walls, frame, especially in the upper range of this grade. Movement may be appreciable on upper levels of tall structures. Underground pipe lines completely out of service. If students are having difficulty brainstorming drawings for the different levels of the Mercalli Scale, have them brainstorm ideas with their partner or as a group. Anticipate the Hazards. Fall of plaster in considerable to large amount, also some stucco. These forthcoming posts are earthquake scenarios for five of the potentially biggest "big ones" projected to strike the contiguous United States. Powered by Create your own unique website with customizable templates. At the time the Richter scale was in use, but the shaking effects of the quake didn't fit the Richter's Modified Mercalli Intensity scale. Primary Waves Find out about primary waves which are the first earthquake waves to reach reporting stations. Trees shaken strongly - branches, trunks, broken off, especially palm trees. The scale lists criteria that permit the seismologist to represent the severity of ground shaking in a community or part of a community by a number. The moment magnitude for this event was measured at 9.5.). Dishes, windows, doors disturbed; walls make cracking sound. The San Francisco earthquake of 1906, which measured 8.3 on the Richter Scale. It does not matter whether you Dozens of intensity-prediction equations[21] have been published to estimate the macroseismic intensity at a location given the magnitude, source-to-site distance, and perhaps other parameters (e.g. It is the most studiednormal fault in the world ( Earthquake Probabilities for the Wasatch Front Region in Utah, Idaho, and Wyoming ). Fall of chimneys, factory stacks, columns, monuments, walls. It's not if and earthquake strikes but when, how hard, and how might it affect the area. At night, some awakened. Copyright Fall of cornices from towers and high buildings. Landslides considerable from river banks and steep coasts. Because a Big One one the Wasatch Fault is more personal, I've done more research on it. Some of the scenarios are bas, Subsidence is the lowering of the ground surface. Broad fissures, earth slumps, and land slips in soft, wet ground. Using these intensity values, and factors that affect the earthquake's effect on the surface, a very deep (something like more than 100 miles (160km)) 7.2 earthquake may only have an Mercalli value of IV or V. But the same magnitude tremor that's shallow (less than 43 miles or 70 km) might bump the intensity value to VII or VIII. It may be helpful to put the scale up on the board and read it aloud with the students. Modified Mercalli Intensity Scale of 1931: Seismological Society of America Bulletin, v. 21, no. Damage great in poorly built structures. Heavy furniture overturned. technology, engineering or math (STEM) educational standards. There are more recent earthquake hazard and risk calculations available, but I have yet to find these risks and hazards incorporated into a full scenario, where costs and losses are calculated for the earthquake. Mercalli Intensity Scale Simulation (I - XII) Marcello Gabrielle 3 subscribers Subscribe 0 No views 1 minute ago This is a simulation fo the modified mercalli scale. Rocked standing motor cars slightly. Knocked pictures against walls, or swung them out of place. Trees, bushes, shaken slightly to moderately. An earthquake of a much lesser magnitude can have just as much (if not more) damage and losses in an area where the buildings and infrastructure are not as prepared, Thank you for taking some time to read my blog. This is what can happen with normal faults. Copyright Local planning commissions use the scale to determine regulations The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. Cracked windows - in some cases, but not generally. Since most material I read referenced that 2008 ShakeOut, that is what this scenario post is based on. The two scales have different applications and measurement techniques. 5), Develop and communicate an evidence based scientific explanation around one or more factors that change Earth's surface Lesson. These values can be best displayed using a contoured map of equal intensity, known as an isoseismal map. The lower values address human response to ground motions, the intermediate values characterize the response of simple structures, and the upper values describe ground failure processes. Felt by all, many frightened. Check out Myrna Martin's award winning textbooks, e-books, videos and rock sets. Sensation like heavy truck striking building. Railroad tracks are bent. However, each earthquake has only one magnitude. Do you agree with this alignment? Outdoors direction estimated. VII. Overturned small or unstable objects, in many instances, with occasional fall. One of the biggest factors is how deep the hypocenter is. Does the booklet make sense? The Wasatch Fault is the most active fault of the seismically active area known as the Intermountain seismic belt, which extends from Montana south to Arizona, and west to Nevada. Wrenched loose, tore off, large rock masses. Copyright http://upload.wikimedia.org/wikipedia/commons/c/c7/US_Navy_110320-M-0145H-063_A_large_ferry_boat_rests_inland_amidst_destroyed_houses_after_a_9.0_earthquake_and_subsequent_tsunami_struck_Japan_March.jpg. It can be labeled the "Mercalli Scale." Bent railroad rails slightly. Trees, bushes, shaken slightly. There are two commonly-used scales to rate earthquakes 1) the Damage total - practically all works of construction damaged greatly or destroyed. How they think engineers and scientists measure earthquake damage? 200% sign-up bonus up to ,000 EDITOR PICKS Even if you already gamble online for real money, playing free casino games can still be exciting and damage. Ask the students: With Words and Pictures: Have students write a sentence on the bottom of each page of their information booklet describing their illustration of the Mercalli Scale rating. (Grade By studying the earthquakes' impacts, can students predict what the Mercalli Scale level would be for each one? Objects are thrown upward into the air. Moreover, construction methods have changed appreciably since the scale was introduced. X. where they live. Felt by all, indoors and outdoors. Awakened few, especially light sleepers. *0G3d$y/!-6!LVQ5R2^1%tI5}U'z1e8M6uZK'f-#uI4\MYZuj1=?1RuN5Oz 10J2"IF$N`Bl8]^>#}G>K^-N*t7&i, A New 3-D Earthquake Simulator for Training and Research Purposes, MTC 17: Hybrid Experimental and Analytical Simulation in Earthquake Engineering - Poster Papers. other structures. Structural engineers usually contribute information for assigning intensity values of VIII or above. Frightened no one, unless apprehensive from previous experience. However, each earthquake has only one magnitude. The intensity differs from the magnitude which is related to the energy released by an earthquake. Pendulum clocks may stop. Engineering to Prevent Natural Disasters: Save Our City! [2][3] The colors and descriptive names shown here differ from those used on certain shake maps in other articles. The second house 5 miles from the epicenter had a couple of Using a deck of cards or by calling random numbers between 1 and 12, have the students show their drawing of what would happen during an earthquake with that Mercalli rating. Simulation activity takes place in a covered space, provided by a monolithic reinforced concrete shear-wall structure, built in a mini-theater fashion, equipped w ith professional quality surround-stereo audio and intensities up to VIII+ in the Modified Mercalli Scale could be achieved. 2004-07-12T09:46:37-05:00 The Kids Fun Science Bookstore covers a wide range of earth science topics. In many earthquake hazards, surface fault ruptures are identified as ground displacement. The lower degrees of the Modified Mercalli Intensity scale generally deal with the manner in which the earthquake is felt by people. Giant Wave Characteristics and Causes, Survive That Tsunami! Casino And will very likely cause. Note that not all lessons and activities will exist under a unit, and instead may exist as "standalone" curriculum. Using various calculations and factors, including depth and distance, the Mercalli scale may often be employed in determining earthquake scenarios and what people may experience in certain earthquake conditions. Play for free July 12, 2022. Shook down loosened brickwork and tiles. Hanging objects may swing slightly. [8], In their 1993 compendium of historical seismicity in the United States,[12] Carl Stover and Jerry Coffman ignored Richter's revision, and assigned intensities according to their slightly modified interpretation of Wood and Neumann's 1931 scale,[a] effectively creating a new, but largely undocumented version of the scale. Copy and paste it, adding a note of your own, into your blog, a Web page, forums, a blog comment, magnitude scale you need to understand that the Richter scale uses There are multiple versions of the MM scale, the one listed here being the 1931 version. Can you think of any examples? Not felt except by a very few under especially favorable circumstances. Units serve as guides to a particular content or subject area. Wood and Frank Neumann in 1931 as the MercalliWoodNeumann (MWN) scale. The Richter scale is more objective, but the Mercalli scale is subjective. Brainstorm with the students how they might illustrate one of the pages. Testing Model Villages in Big Waves, Seismic Waves: How Earthquakes Move Through the Earth. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Intensity Distribution and Isoseismal Maps for the Northridge, California, Earthquake of January 17,1994, USGS Open-File Report 95-92. Disturbances in ground many and widespread, varying with ground material. The effects of any one earthquake can vary greatly from place to place, so there may be many Mercalli intensity values measured for the same earthquake. Visit Ignition. This table gives MMIs that are typically observed at locations near the epicenter of the earthquake. And, interestingly, information on a Wasatch Fault earthquake scenario is easier to find. Standing vehicles may rock slightly. We are glad that this curriculum met your expectations. MTC 17: Hybrid Experimental and Analytical Simulation in Earthquake Engineering - Poster Papers devise a scale to show how an earthquake's effects diminished as you Rating earthquakes helps engineers determine which ones are going to cause the most damage so they can warn people in advance. 5), 3 sheets (cut lengthwise) of white copy paper, 1 sheet (cut lengthwise) of any color construction paper, Variety of crayons, colored pencils, and markers. University of California during the earthquake. An Insight into Coupons and a Secret Bonus, Organic Hacks to Tweak Audio Recording for Videos Production, Bring Back Life to Your Graphic Images- Used Best Graphic Design Software, New Google Update and Future of Interstitial Ads. Assigning of MM intensity values therefore involves use of the original criteria of Wood and Neumann (1931) with amendments and modifications that have been developed in the decades since 1931. Disturbed persons driving motor cars. In this activity, students learn about the Richter Scale for measuring earthquakes and make a booklet with drawings that represent each rating of the Richter Scale. It was later improved by Charles Richter, the father of the Richter magnitude scale.

[14], The categories "catastrophe" and "enormous catastrophe" added by Cancani (XI and XII) are used so infrequently that current USGS practice is to merge them into a single category "Extreme" abbreviated as "X+".[16]. The earthquake was the third largest since recording started in 1900, and it caused one of the deadliest disasters in modern history. The Richter Scale is not used to express damage. The higher numbers of the scale are based on observed structural damage. seconds. Suspended objects made to quiver. Plate Tectonics Simulation Complete the Quiz as you do the simulation. Some, or many, found it difficult to stand. Humans cannot eliminate the hazards but can take steps to reduce their impacts. earthquake waves including layers of the Earth and outlining tectonic There are 72,126 children who spend at least some of their schooling in those buildings. Layer the three pieces of white copy paper in one stack with one piece of construction paper on top for the cover. Wasatch Fault - Central Segments The five central segments of the. Bridges are destroyed. Surveys Explain the different levels of the Mercalli Scale using words or pictures. Do you agree with this alignment? Strike-slip faults are where the blocks of crust have faults that are vertical, or near vertical, and movement on the fault is usually sideways (horizontally). Fault slips in firm rock, with notable horizontal and vertical offset displacements. Engineers often invent scales or systems to use as measurement tools. Get prepared at work and home. Broke dishes, glassware, to some extent. The biggest problem with the magnitude scales (the Richter scale and the Moment Magnitude) is they measure the earthquakes size and energy released, but they do not address the effects of the earthquake. Moved furnishings of moderately heavy kind. Duration estimated. Changed level of water in wells. The WoodNeumann scale was revised in 1956 by Charles Francis Richter and published in his influential textbook Elementary Seismology. Aytun, Alkut Violent -- Buildings may be shifted from foundations. 2012-2017 Ring of Fire Science CompanyAll rights [4] This version "found favour with the users", and was adopted by the Italian Central Office of Meteorology and Geodynamics. Whether it's Texas Hold'em or Stud, all styles of poker require players to have a good understanding of the hierarchy of Also, as in grade I, but often more noticeably: sometimes hanging objects may swing, especially when delicately suspended; sometimes trees, structures, liquids, bodies of water, may sway, doors may swing, very slowly; sometimes birds, animals, reported uneasy or disturbed; sometimes dizziness or nausea experienced. [23], The MMI scale is not defined in terms of more rigorous, objectively quantifiable measurements such as shake amplitude, shake frequency, peak velocity, or peak acceleration. Author: Published on: November 6, 2020 Published in: Uncategorized Published on: November 6, 2020 Published in: Uncategorized It's different to personally feel a big earthquake and see the aftermath. Available on Amazon. Felt indoors by many, outdoors by few during the day: At night, some are awakened. The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. The Mercalli Scale uses List some famous earthquakes and their Richter Scale measurements. And, those numbers are just estimates from the main shock. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes. Damage considerable in (masonry) structure build especially to withstand earthquakes: threw out of plumb some wood-frame houses build especially to withstand earthquakes; great in substantial (masonry) buildings, some collapse in large part; or wholly shifted frame buildings off foundations, racked frames; serious to reservoirs; underground pipes sometimes broken. 1 0 obj << /Type /Font /Name /ZaDb /BaseFont /ZapfDingbats /Subtype /Type1 >> endobj 2 0 obj << /Type /Font /Name /Helv /BaseFont /Helvetica /Subtype /Type1 /Encoding 3 0 R >> endobj 3 0 obj << /Type /Encoding /Differences [ 24 /breve /caron /circumflex /dotaccent /hungarumlaut /ogonek /ring /tilde 39 /quotesingle 96 /grave 128 /bullet /dagger /daggerdbl /ellipsis /emdash /endash /florin /fraction /guilsinglleft /guilsinglright /minus /perthousand /quotedblbase /quotedblleft /quotedblright /quoteleft /quoteright /quotesinglbase /trademark /fi /fl /Lslash /OE /Scaron /Ydieresis /Zcaron /dotlessi /lslash /oe /scaron /zcaron 160 /Euro 164 /currency 166 /brokenbar 168 /dieresis /copyright /ordfeminine 172 /logicalnot /.notdef /registered /macron /degree /plusminus /twosuperior /threesuperior /acute /mu 183 /periodcentered /cedilla /onesuperior /ordmasculine 188 /onequarter /onehalf /threequarters 192 /Agrave /Aacute /Acircumflex /Atilde /Adieresis /Aring /AE /Ccedilla /Egrave /Eacute /Ecircumflex /Edieresis /Igrave /Iacute /Icircumflex /Idieresis /Eth /Ntilde /Ograve /Oacute /Ocircumflex /Otilde /Odieresis /multiply /Oslash /Ugrave /Uacute /Ucircumflex /Udieresis /Yacute /Thorn /germandbls /agrave /aacute /acircumflex /atilde /adieresis /aring /ae /ccedilla /egrave /eacute /ecircumflex /edieresis /igrave /iacute /icircumflex /idieresis /eth /ntilde /ograve /oacute /ocircumflex /otilde /odieresis /divide /oslash /ugrave /uacute /ucircumflex /udieresis /yacute /thorn /ydieresis ] >> endobj 4 0 obj << /S /Normal /C /Normal /P 8 0 R >> endobj 5 0 obj << /Normal /P /TextBox /Div /Frame /Div /Footnote /Note /Endnote /Note /Shape /Figure /InlineShape /Figure /TOA /TOC /TOAI /TOCI /TOF /TOC /TOFI /TOCI /Superscript /Span /Subscript /Span /Strikeout /Span /Underline /Span /DropCap /Figure >> endobj 6 0 obj << /Normal 7 0 R >> endobj 7 0 obj << /O /Layout /WritingMode /LrTb /StartIndent 0 /EndIndent 0 /TextAlign /Start /SpaceBefore 0 /SpaceAfter 0 /TextIndent 0 >> endobj 8 0 obj << /S /Sect /P 27 0 R /Lang (EN-GB) /K 4 0 R >> endobj 9 0 obj << /Nums [ 0 10 0 R ] >> endobj 10 0 obj [ null ] endobj 11 0 obj << /S /Sect /K 12 0 R /P 27 0 R >> endobj 12 0 obj << /S /Normal /C /Normal /P 11 0 R >> endobj 13 1 obj << /Type /Metadata /Subtype /XML /Length 2060 >> stream Scale. forthcoming posts are earthquake scenarios for five of the pages Fault are!
