The strongest earthquake to hit Colorado in more than four decades continues to rattle the state with 13 aftershocks and likely more on the way for days or even weeks, Amy Vaughan of the U.S. Geological Survey’s National Earthquake Information Center in Golden said to The Denver Post.
The largest magnitude aftershock of 3.9 was felt around 8 a.m. on Tuesday morning and centered about 13 miles southwest of Trinidad, according to KOAA.
Vaughan says that there has been no major damage from the aftershocks and that their frequency and intensity will diminish over the coming days, the Boston Herald reports.
Monday night’s magnitude-5.3 quake struck just hours before a magnitude-5.8 temblor in Virginia shook much of Washington D.C. and the East Coast, the Associated Press reported. Both the Colorado and Virginia quakes are extraordinarily rare natural events for those regions. According to the USGS, an 1882 earthquake -- with an estimated magnitude of 6.6 -- near what is now Rocky Mountain National Park is believed to be the largest recorded in the state.
