There are a notable amount of earthquakes near Clarksville, Indiana. However, they aren’t so frequent or so large that they cause much concern. However, that doesn’t mean that impactful quakes can’t happen.

On June 18, 2002, a magnitude 4.6 quake centered in Evansville, Indiana, hit the region. Evansville is about 2 hours west of Clarksville.

Another impactful quake was centered less than 2 and a half hours away from Clarksville. A magnitude 5.4 earthquake hit on April 28, 2008. There were 2 large aftershocks, with the last occurring on May 1, 2008.

Around 4000 years ago, a magnitude 6.9 earthquake hit Indiana. It was centered in Vallonia, Indiana, which is about an hour northwest of Clarksville. Studies of the geology of Indiana show that earthquakes with magnitudes up to 7.5 have occurred in the past.

Other historical quakes have occurred. A large quake on September 27, 1909, damaged buildings. In 1811, quakes of magnitude 7.2 and 8.2 struck within a few hundred miles of Clarksville. This quake caused extensive damage across the Midwest.

Why Does Clarksville, Indiana, Experience Earthquakes?

Clarksville, Indiana, experiences earthquakes because it is located near two active seismic zones in the Midwest. A small magnitude 2.5 earthquake struck nearby on June 3, 2023. Small quakes like this are normal.

Clarksville is close to the Wabash Valley Seismic Zone. This seismic zone is located in southwestern Indiana and neighboring southeastern Illinois. Nobody knows why active faults exist here though some think it’s part of another fault system to the southwest.

The bigger fault system believed to be connected to the Wabash Valley Seismic Zone is the New Madrid Seismic Zone. This seismic zone is more active, with quakes occurring frequently. Since Clarksville, Indiana, experiences shaking from both seismic systems, residents experience many more earthquakes than the average Indianan.

Clarksville, Indiana, lies in a drained floodplain created by the Ohio River. While it’s almost 500 feet above sea level, it isn’t hilly terrain like some of the surrounding forests. Clarksville is also a city environment which means some wildlife that isn’t suited for urban life is not present.

Eastern rat snakes are common garden critters found near homes. They’re long at up to 6 feet, but they’re relatively docile and nonvenomous. As their name implies, they eat rats and other pests. 

Blue catfish are fished from the waters of the Ohio River outside of town. Some are huge, with the most giant blue catfish on record for the State of Indiana weighing 104 pounds.

While Clarksville, Indiana, doesn’t see as many deer as in more rural areas, white-tailed deer still thrive in the region. They also cause almost 15 thousand car accidents in the state every year. Deer are frequently spotted in downtown Louisville near Clarksville, so they aren’t afraid of city living.

A more dangerous critter living within Clarksville is the black widow spider. These spiders release a neurotoxic venom that causes severe symptoms. However, they usually don’t kill people.

What Does Wildlife Most Likely Do During an Earthquake?

Since large earthquakes are not common in Clarksville, Indiana, most wildlife isn’t concerned with experiencing earthquakes. However, that doesn’t mean they don’t react when one occurs.

Most wildlife panics. This panic causes some animals to bunker down. Others will freeze in place, and some will try to run to safety. There is a lot of anecdotal evidence that says animals detect earthquakes in advance and seek shelter early.

Does Indiana Wildlife Detect Earthquakes?

Lots of people believe that animals predict earthquakes. Scientists have yet to verify this.

Lots of people believe that animals predict earthquakes. Scientists have yet to verify this.


While scientists are still trying to prove it, it’s common lore that some animals sense when an earthquake is coming. The common scientific theory is that when an earthquake happens, two main kinds of seismic waves are released simultaneously. Because one travels faster, it may be sensed first.

Some animals and people can detect the first wave that arrives, called P waves. These benign waves hit seconds before the destructive S wave. This may be why some animals grow uneasy or act very strangely seconds before an earthquake.

Animals may detect other subtle hints of earthquakes that humans haven’t figured out. For example, some species may notice variations in electromagnetic fields, slight ground tilting, or groundwater disturbances. There is research underway about the effects earthquakes have on these things though there are no definitive answers.
