  • 1. Analyzing andPredicting Earthquake Data (GIS) Samantha Weed
  • 2. Significant Earthquakes
  • 3. Big Earthquakes
  • 4. 2010
  • 5. Combined Data 7 102 1 8 5 9 3 6 4
  • 6. Top 10 “Overdue” Earthquake Locations (No particular order)1- California: This group of earthquakes is located on the North American plate, as well asthe fault line experiencing plate movement coming from the North. This cluster ofearthquakes is located on the coast line of California, near the San Adreas Fault. It is alsoextremely low populated of earthquakes that occurred in 2010. This area has several big andsignificant earthquakes.
  • 7. Top 10 “Overdue” Earthquake Locations (No particular order)2-Alsaka: This cluster of earthquakes is located on the Pacific plate region, as well as ona subduction zone. Plate movement is occur also. High population of both Big andSignificant earthquakes. 3-4 earthquakes occurred in 2010. Meaning earthquakes areoverdue to occur in this area.
  • 8. Top 10 “Overdue” Earthquake Locations (No particular order)3- Guatemala: The Plate boundary that the earthquakes are found upon is locatedon the Cocos Plate. This boundary are covered in both big and significantearthquakes, yet there are few earthquakes that took place in 2010.
  • 9. Top 10 “Overdue” Earthquake Locations (No particular order)4- Chile/Peru: These earthquakes are located in the South American Plate, which isexperimenting plate movement from both the east and the west. This western coastline is covered in both significant and big earthquakes, yet 7-9 that took place in 2010.
  • 10. Top 10 “Overdue” Earthquake Locations (No particular order)5-Turkey: This massive clump of big and significant earthquakes in located inthe Eurasian plate and plate forces are coming from the west. This earthquakesare sitting there, waiting to erupt, yet in 2010 it seems that only 1-5 earthquakesoccurred in this region.
  • 11. Top 10 “Overdue” Earthquake Locations (No particular order)6-Burma/China: There are significant amounts of big and significantearthquakes in the Burma and China area, yet the number of earthquakesthat happened in 2010 (only one dot), allows me to believe that a greatnumber of quakes will be coming shortly.
  • 12. Top 10 “Overdue” Earthquake Locations (No particular order)7-Japan: These earthquakes are in the Eurasian Plate.This fault line is linedwith both big and significant earthquakes, as well as few earthquakes thatoccurred in 2010. Based on the number of big and significant earthquakes, Ipredict this area of Japan is awaiting an earthquake.
  • 13. Top 10 “Overdue” Earthquake Locations (No particular order)8-Philppines: These earthquakes are in the Eurasian Plate. This fault line is hasa clump of big and significant earthquakes, there are only few earthquakesthat happened in 2010. The Philippines are also a common earthquake area.
  • 14. Top 10 “Overdue” Earthquake Locations (No particular order)9-Afganistan:These earthquakes are in the Eurasian Plate. This area isscattered with with big and significant earthquakes. There seems to bearound 5 dots in the area, meaning earthquakes have occurred in 201.Yet since the area is quite large and populated with both big andsignificant earthquakes, I predict that Afghanistan is over due for anearthquake.
  • 15. Top 10 “Overdue” Earthquake Locations (No particular order)10-Mongolia: These earthquakes are in the Eurasian Plate. This area has noearthquakes that occurred in 2010, and big and significant that haveoccurred in the past. Since no earthquakes have occurred in the presenttime I believe Mongolia is overdue for large a earthquake.
  • 16. Response Question: Response: What new tools or With the on going devolvement of satellite methods (from NASA), seismologists are hoping to be able to predict techniques are both time and location of future earthquake. An seismologists using to example is the Interferometric-Synthetic Apertureof an (InSAR) method. This is when two radar images Radarhelp them better predict tectonic area go through a process called data fusion (combination of data), and any movement in the ground earthquakes? are detected at the surface. This method with the combined with satellite views allows seismologists to determine were high strains are beginning to form. Another new technique/tool that seismologists use is infrared (IR) radiation, when attached to a satellite IR is able to see hot spots. When seismologists examined infrared data that had been collected by one of NASA’ s satellites, it was dicovered a warning in the ground, just before a powerful earthqauke hit Gujarat.
  • 17. Response Question: Response:What have you learned about Seismologists look at where earthquakes and earthquakes have occurred in the past (big earthquake prediction? and significant earthquakes), as well as how recent the area has experienced an earthquake and the magnitude. Also they use Infrared Radiation and satellites to discover hot spots.
  • 18. Response Question: Response:What factors influence Seismologists use IR, satellites and Interferometric-Synthetic Aperture earthquake prediction? Radar to detect movement in the ground, as well as hot spots. When Seismologists use Infrared Radiation from satellites they are able discover warnings in the ground. New technology influences how seismologists are able to predict earthquakes, based upon new techniques that surface.
  • 19. Response Question: Response:Where on Earth do most of • Most earthquakes occur in the really big earthquakes the circum-Pacific seismic belt, which is found along strike? the rim of the Pacific Ocean. This is were 81 % of the worlds largest earthquakes occur. This belt extends from Chile, and stretches northward along South American coast. This belt 70,000 deaths in Peru the 1970’s.
