tectonic plates- move in 3 ways
1. collide w/ eachother
2.seperate from eachother
3. slide against eachother
when plates are moved to the breaking point it causes an eartquake
an earthquake is a seismic wave
west Virginia has never had an eartquake

Seismology is advantageous because it can help predict earthquakes. It can also help compile earthquake statistics and data for future use.
"Important" or significant earthquakes can be measured in most damage, most fatalities, or largest magnitude. In the 20th century the earthquake with the most fatalities was in Iran on June 1990 with 50,000 fatalities. The largest earthquake was magnitude 8.3 in the Kuril Islands on 4-Oct-1994. The 21st century surpasses the 20th century with earthquakes of a higher magnitude (9.0) and higher fatality count (over 200K deaths in Sumatra).
