Magnitude-4.0 earthquake beneath Mauna Loa
The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.0 earthquake beneath the Island of Hawaii at 4:25 a.m. Tuesday.
According HVO, the earthquake occurred underneath Mokuaweoweo, Mauna Loa’s summit caldera, at a depth of 1.2 km (0.74 mi).
The USGS “Did you feel it?” Website received only one felt report within an hour of the earthquake. This report described light shaking (Intensity III). At that intensity, damage to buildings or structures is not expected. The lack of felt reports is consistent with the remote location and shallow depth of the earthquake.
The earthquake this morning appears to be isolated. As of 6:30 a.m., HST, no aftershocks have been observed. HVO’s deformation monitoring instruments registered the earthquake but show no significant change in deformation rates or patterns that would indicate increased volcanic hazard at this time.
