1. What patterns do you see in the distribution of earthquakes across the continental United States?
When conducting research on the earthquake patterns across the United States, it becomes obvious that the majority of the earthquake activity in the continental U.S. centers on the western coastal region which includes California, Oregon, and Washington as well as the Alaskan western coastal region. This area is, according to geological scientists, one of the most active regions for earthquakes in the world as it is an area where the tectonic plates of the Pacific Plate and the North American Plate meet. Here we have what is defined by geologists as a subduction zone where the North American Plate is riding over the Pacific Plate. (USGS, 09/11/2012)
2. Locate your home on this map and make a note of the relative risk to you by indicating the color where you live. The USGS also reports on earthquakes around the world.

In researching the area where I reside, Clinton, Iowa, it was noted that there is no risk for an earthquake around my area. There was an earthquake that happened on September 9th, 2012 in Oklahoma which was a 3.4 magnitude (USGS, 09/11/2012)
3. What patterns do you see in the distribution of earthquakes around the world?
In researching the global earthquake it looks that the region called the Pacific Rim of Fire is the most active of all around the world. This area is noted for its seismic activity as four major tectonic plates converge in this region. These plates are the Pacific Plate, the Eurasian Plate, the Indo-Australian Plate, and the North American Plate. As to the distribution of the activity around the world the majority of the world’s...
