REPORT AN EARTHQUAKE

• When you click the link below, it will take you to a page maintained by the U.S. Geological Survey.
• Larger earthquakes that were strongly felt will be posted on the list. Select the earthquake you felt if it is listed.
• Please submit your report even if a large number of reports have already been submitted. Each new report adds to the database and helps confirm the accuracy of it.
• If you do not see an earthquake that you felt on the list, please click on "New Earthquake" on the lower left of the page.
• Your individual report will be used only for purposes of scientific analysis and your confidentiality will be maintained. We sincerely thank you for your participation.

SHOULD YOU MAKE AN EARTHQUAKE
REPORT WHEN YOU ARE NOT SURE?
 

Please do not hesitate to report minor shaking that you think might have been an earthquake, even if there have been no news reports of an earthquake. Very small earthquakes (2.5-3.0 magnitude) are commonly felt only in a small area near the epicenter as a brief jolt or shake. Many people do not immediately recognize these events as earthquakes and do not report it to local officials.
 
The staff of the Ohio Seismic Network will examine seismograms from one or more of the 22 seismograph stations across the state and determine if an earthquake was recorded at the time noted on your submitted form. We will send you an email with the results. Genuine seismic events will be posted on the Ohio Seismic Network web site.
 

WHAT HAPPENS WITH YOUR REPORT
 

Thank you for taking the time to fill out an earthquake-report form. The Ohio Seismic Network of the Division of Geological Survey of the Ohio Department of Natural Resources works closely with the U.S. Geological Survey on earthquakes that occur in and near Ohio.

• Your observations of what you felt during an earthquake in Ohio are immediately forwarded to the Ohio Seismic Network.
• We use these data to determine the severity of a particular earthquake and pass this information to emergency officials of the Ohio Emergency Management Agency.
• In follow-up analyses, we use your report to determine the amount of shaking that occurred at your location and then correlate this observation to the type of surficial sediment present in the area.
• This information will eventually allow us to construct maps that depict the seismic susceptibility of different types of surficial sediments across the state.
