Pueblo Viejo-Quixal Seismograph Network, 13 February 1979 through 10 March 1981 (Technical Report #1)

During the 24 month period from 13 February 1979 through 10 March 1981, approximately 4400 local and regional earthquakes were recorded by the Pueblo Viejo-Quixal Seismograph network. Of the 4400 events recorded, 2600 foci were located. This report is to summarize the results of the seismic monitoring program during the period mentioned above. During this period, six regional trends of activities were delineated, two of which were located in the vicinity of the Pueblo Viejo Dam Site. Accumulation of the recorded earthquakes now permit us to draw a conclusion on the recurrence time with an acceptable confidence limit.
