The Great Southeast ShakeOut Earthquake Drill 2023

Many people do not realize that Charleston is in an earthquake zone. In 1886, an earthquake with a magnitude estimated between 6.9 and 7.3 caused 100 deaths and damage to about 7,000 buildings.

This is why older buildings in our area have earthquake bolts on the sides of these structures.  These bolts hold poles together that were used to repair and strengthen brick walls. They take many interesting shapes, such as stars and crosses. To read more about these iron bolts, click here.

Dr. Erin Beutel, College of Charleston Geology & Geosciences Department, provided Tidelines with the following map from the USGS that shows the areas with the highest and lowest earthquake vulnerability. As you can see, Charleston is in the risk zone.

This year’s International ShakeOut Day is October 19, 2023, when millions of people worldwide will participate in earthquake drills at work, school, or home.

At 10:19 am (local time) on 10/19/23, you can join more than a million people across the Southeast U.S. practicing earthquake safety.

It’s actually a good idea to practice earthquake safety in different situations each year, and ShakeOut organizers are here to support you. For more information, click here.
