Aftershocks can often occur hours or days after an earthquake, sending additional tremors through the earth. However, new research suggests that some modern earthquakes may be aftershocks themselves from some of the strongest earthquakes recorded in the 1800s.A new study, which was published in the Journal of Geophysical Research: Solid Earth, says that there may have been frequent aftershocks from a trio of quakes that occurred near the border of Missouri and Kentucky between 1811 and 1812. Further, a separate…

Recent research indicates that parts of the central and eastern United States may still be experiencing aftershocks from significant 19th-century earthquakes. The study analyzed seismic data from three historic quakes, concluding that some modern seismic activity in these areas could be long-lived aftershocks, mixed with background seismicity.Aftershocks follow large earthquakes — sometimes for weeks, other times for decades. But in the U.S., some areas may be experiencing shocks from centuries-old events.In the 1800s,…
