Magnitude 3.5 earthquake near KCI was caused by mine collapse: USGS

The U.S. Geological Survey has determined that a magnitude 3.5 earthquake that jostled the Kansas City metro area last month was caused by a mine collapse.

The quake, which had an epicenter near Ferrelview in Platte County, just a few miles east of Kansas City International Airport, was reported around 1:45 p.m. March 15. The quake had a depth of about 1 kilometer, according to USGS.

People throughout the metro area reported that they felt weak or light shaking, USGS said.
