Summary:

This document describes an earthquake that occurred in 1973 at a depth of 40 to 50 kilometers north of Hilo on the island of Hawaii. The location of the earthquake was centered beneath the east flank of Mauna Kea, a volcano that has been historically dormant but active within the last 4000 years. Aftershocks were restricted to a depth of 55 to 35 kilometers with the vent and its aftershock sequence being located in an area that was not normally associated with the seismicity of the Mauna Loa and Kliauea calderas. While the earthquake was a double event, the epicenters trending from Northeast to Southwest, the earthquakes were clearly not associated with volcanic activity that was normally associated with Mauna Loa and Kilauea. This may indicate a deep seated prelude to a resumption of activity at Mauna Kea.
