TEKONSHA, MI (WTVB) – There have been no reports of damages or injuries from the minor earthquake that rattled the region late yesterday morning with an epicenter 14 miles north of Coldwater in Calhoun County’s Tekonsha Township. More people apparently heard rather than felt the quake that measured 3.3 on the Richter scale with many of the callers who contacted 911 dispatchers saying there had been an explosion or sonic boom kind of sound with the rumbling or shock wave lasting 3 or 4 seconds.
The U.S. Geological Survey’s website said people reported feeling the earthquake as far west as Holland, north to Grand Rapids, east into Lenawee County and as far south as Northern Indiana and Northwest Ohio. U.S.G.S. geophysicists seem to have differing opinions about the relationship between yesterday’s quake and the May 2, 2015 4.2 magnitude earthquake that occurred in Kalamazoo County south of Galesburg. Scientists can’t agree on whether or not yesterday’s event was an aftershock of the previous quake nearly two months ago nor can they concur if it was on the same fault line.
Tuesday’s temblor occurred at 11:42 a.m. with the epicenter at the southeast corner of Warner Lake on 12 1/2 Mile Road and 3.1 miles beneath the surface.
The strongest quake ever felt in the region was a 4.6 magnitude quake that hit the Coldwater area in 1947 and some believe is proof of a fault buried deep below southern Michigan.
