chances of earthquake in arkansas?

Answer 1

The chances are "certain".

Small eathquakes commonly regster in the Northeast corner of the state (in the Blytheville area). This is due to the New Madrid fault, which produced a series of devastating earthquakes in 1811 and 1812. Just outside of Arkansas in Missouri, earthquakes occur every few days. If one of these were to be as strong as this dangerous fault system has the potential to produce, it would have major effects on Arkansas and other nearby states as well. Other areas of Arkansas see small quakes. The most recent have been around Conway (October 17, 2006, magnitude 2.8) and and Ash Flat (January 17, 2007, magnitude 2.5)

Answer 2

According to seismic maps I have seen, the tri-state region (Arkansas, Tennessee, Missouri) is high for earthquake activity. I don't remember the rest of the state having any elevated risk. The (supposed) biggest earthquake is historic times occurred near New Madrid, New Spain (Missouri) sometime after 1800.

Answer 3

The New Madrid Fault runs through northeastern Arkansas.

The New Madrid was the source of the strongest earthquake known to have happened in North America in the early 1800s.

It is way overdue to rumble again.

Answer 4

Very low, less then .5% in 100 years for a magnitude 5.0 or more

You can map a probability map based on ZIP code and put in a time period to determine the probability

use 72401 for a zip code to see the Madrid fault

Answer 5

Small, but not zero. There was a big one in the early 1800's.

Answer 6

Probably slim. The last time I was in Florida, there was a small but noticealbe quake.

Answer 7

Not much
