Key Observations to note: • Soupy and unconsolidated sediments • Lack of hemipelagic sediment in core tops • Lack of oxidation in core tops (<1‐5 years) 1/22/2014 Possible 2004 Deposit Core Location Map. Chlieh, et.al. 2007 1 2 3 4 5 Flattening Core Log data to Stratigraphic Horizons offshore Sumatra A) Map of core locations and sediment sources B) Core data C) Flattened core data The likely implications for these correlations: • Triggering was synchronous (deposition of these turbidites spans minutes to several hours, impossible to evaluate with radiometric ages) • Triggering was regional in extent (especially demonstrated in slope cores that have unique sedimentary sources) Correlations Ranked by certainty Constrained by: • geophysical flattening • Radiocarbon ages • Stratigraphic order 1/22/2014 Earthquakes generate strong ground shaking that attenuates with distance from the ruptured earthquake fault…. Landslide slope stability is based on this generalized force balance. Peak Ground Acceleration (PGA) is plotted in units of g (g = 9.81 m/s2), for earthquakes of magnitude 6, 7, 8, and 9. Factor of Safety Stable when RF/DF > 1 Unstable when RF/DF < 1 Landslide concentration in relation to the total co‐seismic slip distribution of the fault rupture Gorum et al., 2011 Heterogeneous Slip = Heterogeneous Landslide Concentration Distances plotted for the fault and bathymetric geometry for the subduction zone offshore Sumatra. Rdist = Fdepth + Fdist 1/22/2014 Modeled ground motions measured at sites PGA is plotted for four earthquake magnitudes 6, 7, 8, and 9.

Project Report Outline Lab Time (log in, check email, create a map, and place the map on the server) Class Review Preview Next Class GIS update • Please be on the look out for cool maps, online GIS systems, and other GIS related news. • I want you all to participate in this part of the class. • I suggest you sign up for at least one email listserv (ESRI, google, Geocommunity, GIS User, Linkedin, etc.) so you can keep up to date with the latest GIS and Remote Sensing News. • We will take a look at your cool stuff at the beginning of class each day we meet. http://www.geocomm.com/ http://www.cfr.org/interactives/GH_Vaccine_Map/#map http://www.latimes.com/business/hiltzik/la‐fi‐mh‐ antivaccination‐movement‐20140120,0,5576371.story http://www.gisuser.com/ http://tamutimes.tamu.edu/2014/01/21/asian‐ air‐pollution‐affecting‐worlds‐ weather/?utm_content=bufferd4bfd&utm_mediu m=social&utm_source=facebook.com&utm_cam paign=buffer#.Ut8ertLTnwd January 21, 2014 Asian Air Pollution Affecting World’s Weather Extreme air pollution in Asia is affecting the world’s weather and climate patterns, according to a study by Texas A&M University and NASA’s Jet Propulsion Laboratory researchers. This interactive map visually plots global outbreaks of measles, mumps, whooping cough, polio, rubella, and other diseases that are easily preventable by inexpensive and effective vaccines. The Global Health Program at the Council on Foreign Relations has been tracking news reports on these outbreaks since the fall of 2008. This project aims to promote awareness of a global health problem that is easily preventable.

If so, what did you learn? 1/22/2014 Ground motion contributions to core site source areas • For any generic earthquake with a given Mw, each source areas have similar ranges of shaking intensity • Each site has a similar capacity to shake with intensity related to Mw PGA and AI vs. slope: One of these is not like the other. AI range increases with Mw PGA range decreases with Mw Ground motions at core site source areas. • Is this difference in site response persistent for a specific earthquake? • Did these four sites all receive a similar range in ground motion intensity as suggested by this generic model? • Let’s see>>>>
