The Earth is a combination of sand, rocks, molten lava; this definition would force one to conclude that our world is a contradiction in terms. This is not the case, we dwell on solid rock that is the surface of the Earth; the overwhelming facets of the Earth exist below the surface. It is here that we will find the tectonic plates of the Earth and cause for Earthquakes. An earthquake occurs as the two blocks of the earth suddenly slip past one another ( Generally a quake will occur without warning, although many times there may be a foreshock (smaller earthquake near epicenter, similar to an aftershock), which is usually mistaken for the Earthquake until the actual higher magnitude quake occurs. These shifts seem to happen without warning, however, upon observation and tracking of geological survey, structures, and pattern, it is possible to decipher the probable location of an earthquake. The United States Geological Survey map is a valuable tool when attempting to decipher whether a particular state is an Earthquake hotspot. Upon review of the Geological survey, one will notice that Pacific coast and the islands in the Pacific Ocean are furthermost susceptible to the quakes. Hazard levels range the low teens to over fifty percent. Kentucky, Tennessee and Missouri rest on the New Madrid Fault line; subsequently these are states that share the red zone symbolizing the greatest risk for activity. We will notice that further inland the states experience less hazard until we begin approaching the Southeast states (southern tips of a few Northeastern states). The 2008 Hazard Map leads one to speculate if a fault area within the South, or the offshore faults off the coast of South Carolina would produce quakes capable of devastating stats surrounding Tennessee. It’s possible to consider the Northeast considerably Earthquake safe, although an increased risk exists in Northern New York & Vermont, with several mediocre points in Maine ( The survey exhibits that California is exposed to the furthermost earthquake hazard. California’s
