A survey of microearthquakes of the Virgin Islands and eastern Puerto Rico showed that it is possible to find quiet recording sites for high-gain, high-frequency seismographs and to record as many as 10 to 15 micro-events per day. A site at Lameshur Bay, St. John, Virgin Islands, was as quiet as some of the best sites occupied in western North America. Microearthquake activity approximately coincided geographically with activity for larger earthquakes from 1900 to 1964. These events were located along the Anegada trough, the Puerto Rico trench, and the northern end of the Lesser Antillean arc.
