The United States Geological Survey reports a 2.0 magnitude earthquake at 8:09 p.m. January 16, 2018 - exactly the same time a meteor flashed through the sky in Michigan.

The earthquake was a very weak earthquake having what is called a "local magnitude" (Ml) of 2.0. This USGS map shows a "meteorite" notation for the quake. A 2.0 magnitude earthquake would not be felt by humans.

The map above shows where the USGS detected the earthquake. The epicenter was reported as eight kilometers west-southwest of New Haven, Mich.

The earthquake occurred on the surface, which is different from many earthquakes having depths of several miles below the Earth's surface.

A surface earthquake at the same time as the spotting of a meteor could mean one of two things.

The loud sound many experienced could produce a "shock wave". The boom would hit ground, or in this case the lake, and push on the ground. This would register a vibration.

The other possible reason for a shock wave would be part of the meteor's impact.
