JOHNSON CITY, Tenn. - Many people are asking a lot of questions about this earthquake. News 5 checked with a Geology Professor at East Tennessee State University for answers.
We've learned the earthquake in Eastern Kentucky is not uncommon and the shaking we felt here was part of the shock from the earthquake.
Professor Chris Gregg showed us an Earthquake Hazard Map to explain the chances of ground shaking across the United States. "Eastern Tennessee and the Tri-Cities region are part of a known Earthquake Hazard Zone. The frequency of earthquakes and magnitude of earthquakes are less and smaller than in some other areas of the United States," said Gregg.
We've learned the more shallow the earthquake, the more damage it can cause. It's also more likely people will feel shaking.
