Geophysical investigations of the western Ohio-Indiana region. Annual report, October 1982-September 1983
Earthquake activity in the western Ohio-Indiana region is monitored with a precision seismograph network which consists of nine stations located in west central Ohio and four stations sited in Indiana. Five local and near regional earthquakes have been recorded during this report period. Three events were located outside the array, near the cities of Kalamazoo, Michigan, Cleveland, Ohio and Cincinnati, Ohio. Two events occurred in the center of the Ohio array. A focal mechanism was calculated for the larger of these two events. This focal mechanism shows mainly strike slip motion on steeply dipping nodal planes, striking at N35/sup 0/-45/sup 0/E and N50/sup 0/-70/sup 0/W. Both of these planes correspond to local structures. 7 references, 12 figures, 6 tables.
