Earthquakes have occurred in and around Kentucky in the past and continue to occur (Fig. 1). The strongest historic earthquake recorded inside Kentucky’s borders was the magnitude 5.2 Sharpsburg earthquake of July 27, 1980, in Bath County.

How often do earthquakes happen in Kentucky?
While small earthquakes may be fairly common in Kentucky, damaging earthquakes don’t happen very often. The majority of the state is only expected to have 4-10 major earthquakes every 10,000 years. A major earthquake is a magnitude 7.0 or above.
Where does the fault line run in Kentucky?
Kentucky River fault system is one of a series of major regional fault systems that extends east-northeasterly across Kentucky. The western members of these fault systems are the Shawneetown and Rough Creek (discussed separately as Class C faults) fault systems in southern Illinois and western Kentucky.
Is Kentucky overdue for an earthquake?
“The ground could even liquify and turn to mud.” And how likely is it? Seismologists estimate that the New Madrid Seismic Zone has a 25 percent to 40 percent chance of producing a significant quake within the next 50 years, according to Lexington-Fayette Urban County Government. So, we’re saying there’s a chance.
Is Louisville KY on a fault line?
Most people don’t know that Kentucky is one of 16 states at the highest risk for earthquakes, according to the United States Geological Survey (USGS). That’s because the western portion of Kentucky sits on the most active fault in the central and eastern United States (the New Madrid Seismic Zone).
Does Louisville get earthquakes?
Earthquakes are certainly a relatively rare occurrence in the Louisville area. In terms of the city’s own risk assessment, it’s well below problems like flooding.
What was the largest earthquake in Kentucky?
magnitude 5.2 Sharpsburg earthquake
The strongest historic earthquake recorded inside Kentucky’s borders was the magnitude 5.2 Sharpsburg earthquake of July 27, 1980, in Bath County. The quake caused an estimated $3 million in damage in Maysville (Fig. 2).
Which two states have the least number of earthquakes?
Florida and North Dakota are the states with the fewest earthquakes. Antarctica has the least earthquakes of any continent, but small earthquakes can occur anywhere in the World.
What state has the highest seismic risk?
California
California has more earthquakes that cause damage than any other state. Alaska and California have the most earthquakes (not human-induced).
How many fault lines are in Kentucky?
There have been many faults that have been mapped in Kentucky but only one is known to be active. The Reelfoot Fault is the only active fault in Kentucky and it is found in western Kentucky. It is a large fault that runs from the northwest to the southeast within the Reelfoot Rift.
Where is the Madrid fault line in KY?
New Madrid Seismic Zone (NMSZ), region of poorly understood, deep-seated faults in Earth’s crust that zigzag southwest-northeast through Arkansas, Missouri, Tennessee, and Kentucky, U.S. Lying in the central area of the North American Plate, the seismic zone is about 45 miles (70 km) wide and about 125 miles (200 km)
What would happen if the New Madrid fault line went off?
Nearly 200 schools and over 100 fire stations would be damaged; 37 hospitals and 67 police stations would be inoperable the day after the earthquake in the state of Missouri. Thousands of bridges would collapse and railways would be destroyed, paralyzing travel across southeast Missouri.
Will there be a big earthquake in 2021?
Maximum intensities are indicated on the Mercalli intensity scale. The year 2021 was a very active period for global seismicity, with 19 major earthquakes, three of which were over 8.0, and was also the most seismically active since 2007.
List of earthquakes in 2021.
| Number by magnitude | |
|---|---|
| 7.0−7.9 | 16 |
| 6.0−6.9 | 141 |

When was the last major earthquake in Tennessee?
Apart from the 1811–12 New Madrid earthquakes, only three major events have struck the state of Tennessee, in 1843, 1865, and 1895.
What fault runs through Tennessee?
Tennessee is in two seismic zones, the New Madrid and the East Tennessee zone.
Where are the fault lines in the US?
The New Madrid Seismic Zone (NMSZ) in the Central United States, comprising Arkansas, Illinois, Indiana, Kentucky, Missouri, Ohio, and Tennessee, also has the potential to produce large, destructive quakes—as it did in the winter of 1811-1812.
Was there an earthquake in TN?
Latest and past earthquakes in Tennessee, USA
There were no significant confirmed earthquakes in or near Tennessee in the past 24 hours.
What is the largest fault in California?
The San Andreas fault
The San Andreas fault is the primary feature of the system and the longest fault in California, slicing through Los Angeles County along the north side of the San Gabriel Mountains. It can cause powerful earthquakes—as big as magnitude 8.
What is the only US state that has never had an earthquake?
The Answer:
According to the U.S. Geological Survey’s Earthquake Information Center, every state in the U.S. has experienced an earthquake of one kind or another.
