The magnitude-5.2 earthquake that occurred at 12:02 a.m. Tuesday morning served as a not-so-gentle reminder of the seismic hazard on the Island of Hawai‘i. The quake was felt throughout the State, with reports from as far away as Kapa'a, Kaua‘i.

Large, damaging earthquakes have occurred frequently in Hawai`i in the past and will occur again in the future, as we discussed last week. However, there is a great deal you can do to reduce your personal risk.

The National Science Foundation recently supported a scientific drill hole to examine the long-term growth of a Hawaiian volcano. The objective identified by the principal investigators was to drill through as much as possible of Mauna Kea Volcano and determine the variations in the compositions of the lavas over time.
