From our News Partners at WCBD-TV:
A 1.8 magnitude earthquake has been registered in Summerville. An earthquake under 2.5 usually can't even be felt but it can be recorded by seismograph.
Summerville has been home to several quakes in the past year. Six months ago there was 2.2 magnitude earthquake. Ladson, which is under ten miles from Summerville, has had five earthquakes registered in the past 12 months. Summerville had two, nine months ago, that were similar in strength: 2.5 and 2.3 on the richter scale.
The United States Geological Survey's reports faults within the bedrock in the Charleston area are more susceptible for higher magnitude earthquakes. That's because the bedrock beneath the Charleston area was assembled as continents collided to form a supercontinent hundreds of millions of years ago.
The most damaging earthquake in South Carolina history was back in 1886. The quake caused an estimated $23 million damage.
