International Geophysics -85.17
By: , and 



HYPO71, a computer program for determining hypocenter, magnitude, and first-motion pattern of local earthquakes, was first released in 1971. It is perhaps the first earthquake location program that achieved worldwide usage, as evidenced by the fact that about 1000 copies of the HYPO71 manual were requested and distributed (Lee, 1990). It is included here for historical documentation.
