ABSTRAcr This report is the 60th quarterly bulletin of seismicity in the northeastern United States for the period July - September.1990. Included are geographic maps of the network station and seismicity during the quarter. and of the cumulative seismicity for the 60 quarters. Also included are tables of station locations. epicenters. and all event data for the quarter. An appendix describes the velocity models appropriate for the northeastern United States. IN'IRODUcnON Station operations and seismicity results for the quaner are summarized in three figures and four tables (the formats of the tables are described in the section EXPLANA nON OF TABLES). Figure 1 is a geographic map of NEUSSN stations which were operational during the period; Figures 2 and 3 are maps of seismicity for the reporting period and for the cumulative period from October 1975. respectively. Table 1 is a location list of operating stations; list of epicenters during the reponing period; Table 2 is a chronological Table 3 lists station arrival times, distances, azimuths, amplitudes, and periods for the events of Table 2; Table 4 lists foreshocks, aftershocks, and microeanhquakes occurring the reponing period. during ACXNOWI..EOO~ Partial or full support from various agencies for the operation of the Northeastern Seismic Network (NEUSSN) is gratefully acknowledged. Agencies providing support to members of NEUSSN include the U.S. Regulatory Commission, Office of Reactor Safety Research;the U.S. Geological Survey Office of Earthquake Studies; the National Science Foundation, Geophysics Program; the New York State Energy and Resources Development Authority; and the New York State Science Service. Data from stations operated by Weston Geophysical Research. Inc.. and Woodward-Clyde Consultants are routinely provided to NEUSSN when available. Epicentral and station data for some of the events in Canadanear the U.S. border are provided by the Geological Survey of Canada. Ottawa. In addition to the above operational suppon. equipment has been provided by the Advanced ResearchProjects Agency of the Dept. of Defense and by the Office of Environmental Geology of the U.S. Geological Survey. SEISMICITY During the period July 1 to September30. 1990. a total of 13 earthquakes were detected and located in the northeasternUnited States. In addition. 27 earthquakes are included which had epicenters in Canada, 16 of these events were within 100 kilometers of the U.S.. border. Table 4 includes 1 aftershock. The magnitudes of the 40 earthquakes in Table 2 range from -.3 to 3.7. The magnitude of the event in Table 4 was 2.3. EXA..ANAnON OFTABLS Table 1: List of operating Seismic Stations 1.
