The unrest began being documented March 15, 1980, however it was not immediately recognized as possibly being a precursor to a volcanic event. The seismic events were first recognized as precursor activity on March 20th, 1980 with a magnitude 4.2 under the north flank of the volcano (Which also turned out to be the eruptive and failure point of the volcano on May 18).
