Earthquakes, September-October 1993

Abstract

Three major earthquakes (7.0&le;M<8.0) occurred during this reporting period. the first, a magnitude 7.2 on September 10, struck near the coast of Chiapas, Mexico. the seocond and third, both with magnitudes of 7.0, shook eastern New Guiena on October 2 and October 25. Earthquake-related deaths were reported in India, Japan, Guatemala, Papua New Guinea, and in the United States. The fatalities in the United States were caused by two earthquakes in southern Oregon on September 21. These earthquakes, both with magnitude 6.0 and separated in time by about 2 hrs, led to the deaths of two people. One of these deaths was apparently due to a heart attack induced by the earthquake.
