Map EG-2VERSION 2.0Revised 6/2014EARTHQUAKE EPICENTERS IN OHIO AND ADJACENT AREAS

Michael C. Hansen
This map depicts the approximate locations of earthquakes that were felt in Ohio or near the state border thathad instrumental magnitudes of 2.0 or greater. For purposes of graphic display, some events are not plottedprecisely at their listed coordinates (see catalog at right), especially in areas of multiple events.Noninstrumental earthquake locations and magnitudes have been calculated from historical accounts,including newspaper articles, scientific publications, published and unpublished government reports andrecords, and a variety of other sources. Because of the paucity of original reports for some earthquakes, theselocations and magnitudes may be very imprecise; for some early events, locational errors may be tens ofkilometers. Two eighteenth-century events, in 1776 and 1779, are not plotted on the map because they areknown only from single felt reports recorded by Moravian missionaries in Coshocton County; theseearthquakes may have had epicenters beyond Ohio borders. This map includes most of the small-to-moderate(2.0 magnitude or greater) earthquakes that were beyond the state border but were, or may have been, felt inOhio.
Instrumental recording of earthquakes in Ohio began about 1900 at St. Ignatius College (now John CarrollUniversity) in Cleveland. In 1927, Xavier University in Cincinnati established a seismic station that operateduntil the late 1960s. Bowling Green State University operated a seismic station during the 1970s through themid-1980s. The University of Toledo established a seismic station in the early 1980s. Despite this longhistory of instrumental recording in Ohio, there were never sufficient numbers of stations to precisely locatesmall earthquakes occurring within the state. Therefore, instrumental locations of small earthquakes in Ohioduring this period probably have no greater precision than events located on the basis of felt reports. From1977 to 1992, the University of Michigan operated a nine-station seismic network in the Anna area ofwestern Ohio and precisely located a number of events in this region. In 1986, John Carroll Universityestablished a multistation seismic network in northeastern Ohio and located a number of small earthquakes inthis area; this network ceased operation in 1992.
From 1992 until establishment of the Ohio Seismic Network in 1999, Ohio lacked in-state capability to locateearthquakes. During this period, some small events were detected and instrumentally located by out-of-statenetworks, including the University of Kentucky and the Geological Survey of Canada. However, someinstrumental locations are imprecise because of seismic-station distance and distribution that precludeoptimal triangulation. Seismologists express this epicentral uncertainty by calculating the error ellipse for anevent. Some poorly recorded events may have error ellipses with axes of tens of kilometers (km), whereasprecisely located events may have error ellipses of less than one km. The uncertainties of locations ofinstrumental and noninstrumental earthquakes is well known to seismologists, geologists, and others whowork with earthquake data; however, such information is noted in this report so that individuals andorganizations are aware that the placement on a map of a symbol depicting an earthquake location is agraphic representation of an approximate epicenter based upon available data. Therefore, site-specificdecisions should be based on the quality of the original data for a specific earthquake.
The complete database of Ohio and border-region earthquakes is available online athttps://geosurvey.ohiodnr.gov/earthquakes-ohioseis/ohioseis-home. The database includes a listing ofsome larger earthquakes that were felt or caused damage in Ohio but are beyond the border region as well asa list of doubtful or uncertain events that were reported as earthquakes but were probably of nonseismicorigin. Although derived from previous compilations by academic researchers and governmental institutions,the database has depended heavily on the report and catalog by Seeber and Armbruster (1991), with additionsby John G. Armbruster. Many older events are poorly known and require additional research of newspaperaccounts for complete documentation. Historical research occasionally reveals earthquakes that have not beennoted on previous lists. The ODNR Division of Geological Survey welcomes such new information.

I thank John G. Armbruster of Lamont-Doherty Earth Observatory for his interest in historic earthquakes inOhio and adjacent areas and for generously sharing these data with me through the years. Research on historicalearthquakes in northeastern Ohio by Weston Geophysical Corporation (1979), compiled as part of the impactstatement on the Perry Nuclear Power Plant, was of considerable help in compilation of the Ohio catalog.
