Dziewonski and Gilbert, using a moment tensor representation of the seismic source, presented evidence for precursive compression before deep earthquakes. For the Colombian earthquake of July 31, 1970 (17:08:05.4 GMT, 1.5° S, 72.6° W, h > 650 km), they concluded that a large precursive compression occurred in the focal region, beginning about 80 s before the origin times as determined by ordinary P wave travel times.
