CALHOUN COUNTY, MI (WKZO AM/FM) — A small earthquake that measured 3.8 on the Richter scale took place at 12:10 p.m. Tuesday about 9 miles southeast of Battle Creek. Several residents said they heard and felt some rumbles. Originally, it was reported as a 3.6, but often data on the strength of earthquakes is adjusted as new information comes in.
Residents around Calhoun County, and some in eastern Kalamazoo County, said they heard two loud booms with the second one louder and longer than the first. There were also reports of rattling windows. Others reported noises that sounded like a washing machine off balance or a loud truck passing by their homes. There were no reports of any damage or injuries.
Tuesday’s quake was not as strong as the one in Kalamazoo County on May 2, 2015, which measured 4.2 on the Richter scale. It was centered nine miles south of Galesburg. According to University of Michigan researchers, that was the largest earthquake with a Michigan epicenter since a magnitude 4.6 earthquake struck near Coldwater on August 10, 1947.
The 2015 quake confirmed suspicions for decades that a fault line was located in southeastern Kalamazoo County and experts believe it also was connected to the same fault responsible for the 1947 quake.
