What’s a earthquake? According to the Geology Labs on-line website an earthquake is the sudden release of stored energy, caused by the shifting of tectonic plates. The energy release is a shock wave or seismic wave. The seismic wave is what causes the ground to move or shake, when this occurs we have a earthquake.
According to the 2008 United States National Seismic Hazard Maps a lot of the west coast as far south as Hawaii, and north to Alaska has a lot of earthquake activity. The Pacific “Ring of Fire” (named for the large amount of active volcanoes), has a lot of tectonic activity. ...view middle of the document...
The New Madrid Fault Line has had four of the largest North American earthquakes in recorded history, with moment magnitudes estimated to be as large as 8.0, all occurring within a three-month period between December 1811 and February 1812.
In November 2008, The U.S. Federal Emergency Management Agency warned that a serious earthquake in the New Madrid Seismic Zone could result in "the highest economic losses due to a natural disaster in the United States.
Question: What patterns do you see in the distribution of earthquakes around the world?
Answer: Seems most large magnitude earthquakes happen along the coast, and seems earthquake activity has increased since 2008. As of 6/18/2012 there has been 1292 earthquakes worldwide in the past 7 days. 40 in the United States with a magnitude of 2.5 or greater, out of those 33 are in California, and 3.3 magnitude in Tennessee along the New Madrid Fault Line.

Question: Would you be willing to live in one of the red areas on the map?
Answer: No, out of fear for my children this is not a option. Earthquakes show no warnings, and may happen at anytime, anywhere.
Question: If you and your family were forced to relocate to a red area, how could you use the USGS resources on earthquake readiness to help your family prepare themselves?
Answer: Practice earthquake drills, readiness is key. Teach them not to panic and prepare them for likelihood of a earthquake. Items needed would be a meeting place, flashlights and batteries. Radios, handheld walkie talkies, first aid kits, fire extinguisher, extra food, water and tools.
Question: What are the two most recent earthquakes on this list?
Answer: 2010/01/12 the region of Haiti had 316000 death from a earthquake that measured 7.0 magnitude , 2008/05/12 the Eastern region of Sichuan, China had 87587 deaths from a earthquake that measured a 7.9 magnitude.
