The U.S. Geological Survey’s Hawaiian Volcano Observatory recorded a magnitude-4.2 earthquake north of Molokai at 3:03 a.m. on Thursday.
This earthquake was centered about 40 miles northeast of Kaunakakai, Molokai, at a depth of 10.6 miles. A map showing its location is posted on the HVO website.
The earthquake was felt throughout the island chain, from Hawaii to Oahu, with the USGS “Did you feel it?” website receiving more than 340 felt reports within an hour of the earthquake. Weak to light shaking, with maximum Intensity of IV, has been reported. At that intensity, damage to buildings or structures is not expected.
The Pacific Tsunami Warning Center reported that no tsunami was generated.
The depth, location and recorded seismic waves of the earthquake suggest a source due to bending of the oceanic plate from the weight of the Hawaiian Island chain, a common source for earthquakes in this area. Aftershocks are possible and could be felt.
The earthquake caused no detectable changes in Kilauea Volcano’s ongoing eruptions, on Mauna Loa, or at other active volcanoes on the Hawaii Island.
