Geology Reading Assignment, Given 4/5 due 4/7
Group 1: Read http://news.yahoo.com/s/ac/20110311/wl_ac/8043106_japanese_earthquake_makes_top_five_on_richter_scale_since1900 If you can't get the link to work see it at our blog, trilliumgeology.blogspot.com
Answer these questions on a separate piece of paper.
1.What was the richter scale of the recent Japan earthquake according to the USGS.
2.Name a richter scale 9 quake. When, where, and how many people died in that?
3.What date was the Alaskan Prince William Sound?
4.How do we know the Alaskan quake was a subduction zone quake
5.How many died in the 2004 quake?
6.Where was the 2004 quake and why did so many die?
Draw a subduction zone labeling the oceanic plate, aesthenosphere, convection current, continental plate, subduction zone, trench, and associated volcanic range.

Answer these questions:
1.How quickly does the pacific plate move?
2.What is the result of that movement?
3.What kind of scale is the richter scale based on?
4.Compare what strength a 3 vs a 4 quake would be.
5.What about a 4 vs a 7?
6.What is the most people died in an earthquake, and where is that plate?
*How far will the plate move in 74 years?
Draw a sketch (or print out a map) of the pacific ring of fire Japan, China, the US (including Alaska), Canada, Mexico and Chile. Drawing and labeling the mid pacific ridge, the direction of the plate spreading, labeling the rate at which it is spreading. Draw volcanoes where you would predict them.
