GEOTOURS EXERCISE 11Predicting Earthquakes from Historical SeismicityName:Course:Section:Date:Exploring Geology Using Google Earth1. Visit digital.wwnorton.com/geolabmanual42. Go to the Geotours tile to download Google Earth Pro and the accompanyingGeotours exercises file.Expand the Geotour11 folder in Google Earthby clicking the triangle to the left of thefolder icon. Check and double-click on theNorth Anatolian Fault, Turkey folder to fly tonorthern Turkey. The segments within thefolder show the traces of a series of faults thatcompose the North Anatolian Fault system.The segments are labeled and colored toshow a relatively brief historical record ofearthquake activity along the North AnatolianFault (based on approximate regions thatwere active during each major seismic event...gray faults have not been active during thesemajor events).(a) What is the dominant general patternof major earthquakes along the mainportion of the North Anatolian Faultfrom 1939 to 1999 (i.e., look for a temporalsequence of earthquakes related todirection)?(b) What might cause this pattern?(c) Assuming you are a geologist/geophysicist consulting with the Turkish government, where would you predict would bethe likeliest area to next experience a major earthquake in association with this fault system (based on the data shown)?Check and double-click the c: placemarks to fly to each area location.area11.6 TSUNAMI!297
