The September 3 M5.6 earthquake in Oklahoma left a dramatic trace on GRCC’s seismometer. This station (GRMI), located in the geology lab of the Calkins Science Center, is part of the Michigan Regional Seismic Network (MIQuakes). This earthquake is similar in magnitude to one that shook Oklahoma earlier this year. More information about the earthquake and others in the region can be found on the U. S. Geological Survey’s website.
