United States Fault Lines Map – Earthquakes could also happen in East Coast and in the Midwest Cites
[BestSyndication News] Earthquakes are always a concern out in Alaska and in California, as it is full of fault lines that are continually shifting. There are some fault lines that are overdue to shift, especially the California San Andres fault line that runs through the mountain ranges and close to Wrightwood. But did you know there is a United States Fault Lines Map that illustrates great potentials for earthquakes outside of our state?
New Madrid Fault Line
The New Madrid Fault Line has records of over 4000 earthquake reports since 1974. This fault line is also called the New Madrid Seismic Zone and has potential to devastate the states of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, and Mississippi. The biggest part of the New Madrid Fault Line sits in Missouri.
We often forget that this Midwestern fault line is there, but in 1811-1812 there was a series of earthquakes that shook with estimated magnitudes of 8.1 – 8.3, with several aftershocks of 6.0 magnitudes. Since those big ones, the largest earthquake that this fault line produced was in a 6.6-magnitude quake that happened on October 31, 1895. It's epicenter was in Charleston, Missouri.
The damage from these earthquakes were extensive, and there has been recent speculation by the scientific community that believe that this fault line might be shutting down and moving elsewhere. In an issue of Nature, scientist believe the current seismic activity at the New Madrid Fault line is only aftershocks from the earthquake back in 1811 and 1812.
Ramapo Fault Line
The Ramapo Fault Line spans 300 kilometers and affects the states of New York, New Jersey, and Pennsylvania. These faults run between the Appalachian Mountains and Piedmont areas to the east.
This fault remains relatively inactive, but scientists believe that it could produce some serious earthquakes. There was a study completed in 2008 that believes a 6 – 7 magnitude earthquake will very likely occur from this fault line. The last time this fault was the most active was believed to be 200 million years ago.
San Andreas Fault Line
The last few years Southern California has been preparing for the next big one with government sponsored Earthquake Drills. Scientist are predicting that the next big one with a magnitude of a 7.0 or higher for this fault line will happen any time, it could be now or 10 years from now. They believe the areas that are going to be hit the hardest are going to be Palm Springs and a number of other cities in San Bernardino, Riverside and Imperial counties in California, and Mexicali municipality in Baja California.
