Mauna Loa Volcanoes Swarms Focal mechanisms Data processing Earthquakes

Summary:

This document describes the changes in seismic activity that occurred prior to the 1984 eruption of Mauna Loa, the world's largest active volcano that is located on the island of Hawaii. The pre-eruption earthquake activity in this study was from April, 1983 - April, 1984 as was recorded at the Hawaiian Volcano Observatory. This analysis of activity was selected on the basis of their catalog locations and magnitudes from which 187 events were examined that were located on the northwest flank of Mauna Loa. The focal mechanisms from the summit events were a mix of faulting types without a consistent pattern.
