The 2008 Illinois earthquake was one of the largest earthquakes ever recorded in the Midwest state of Illinois. This moderate strike-slip shock measured 5.2 on the moment magnitude scale and had a maximum Mercalli intensity of VII (very strong). It occurred at 04:36:59 local time on April 18 near West Salem and Mount Carmel, Illinois, within the Wabash Valley Seismic Zone. Earthquakes in this part of the country are often felt at great distances.

Epic center

The epci center is the location on Earth's surface from which the earthquake seems to radiate. It is the point directly above the focus.

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismicity, or seismic activity, of an area is the frequency, type, and size of earthquakes experienced over a period of time. The word tremor is also used for non-earthquake seismic rumbling.

• This illustration show how earthquakes can cause extreme damages and loss of life.

Divergent Boundaries

Get away from me!

At divergent boundaries , plates pull away. They stretch rocks and make them thinner. This is know as tension.

Convergent Boundaries

At convergent boundaries plates collide, causing rock to be squeezed. This is know as stress.

Transformed boundaries

• A transformed boundaries is a plcae where two textonic plates slide past ech other horizontally.
