Why earthquakes occur in Arkansas ?

Arkansas is located near one of the most earthquakes prone areas in the country and this is the main reason why frequent  earthquakes observed in Arkansas.

Earthquakes occur every year throughout the state of Arkansas, but most go unnoticed. … Earthquakes are caused by movement along geologic faults, or fractures in the earth’s crust. When a fault moves, energy is released and transferred through the earth, which causes the shaking experienced during an earthquake.

Arkansas Earthquakes history

Earthquakes have been documented in Arkansas as early as 1699 by missionaries traveling down the Mississippi River near Helena(Phillips Country). Earthquakes are caused by movement along geologic faults, or fractures in the earth’s crust. When a fault moves, energy is released and transferred through the earth, which causes the shaking experienced during an earthquake. Arkansas has hundreds, if not thousands, of faults. Most of these faults are considered inactive; however, faults associated with the New Madrid Seismic Zone are still active. When numerous earthquakes occur in a localized area over a short period of time, it is generally referred to as an earthquake swarm. And these earthquake swarms are observed in Arkansas very frequently, one of the most noticed swarm was Enola Swarm in central Arkansas.

Fault line in Arkansas

The New Madrid Fault, also called the New Madrid seismic zone, is actually a series of faults, or fractures, at a weak spot in the earth’s crust called the Reelfoot Rift. It lies deep in the earth and cannot be seen from the surface. The fault line runs roughly 150 miles from Arkansas into Missouri and Illinois.

Arkansas is one the major place where there are numerous earthquakes can be observed and still research goes on to find out the various other geological reasons. These earthquakes sometimes become very dangerous for the lives and property but as it is a natural disaster they cannot be properly predicted. Either it be small or major earthquake one has to face the consequences.
