Earthquake Monitoring (OhioSeis)

About OhioSeis

The Ohio Seismic Network (OhioSeis) monitors and records seismic activities in the state. The network is comprised of several autonomously recording seismic stations located at state parks and state forests throughout Ohio. Explore a station location map on the IRIS website here.

The ODNR Division of Geological Survey coordinates the network from the Ohio Earthquake Information Center located at the H. R. Collins Laboratory at Alum Creek State Park near Delaware, Ohio. In addition to OhioSeis instruments and exhibits, the facility also hosts U.S. Geological Survey Advanced National Seismic System station ACSO and UNAVCO Plate Boundary Observatory monitoring station ACSO.
