Light 4.6M quake south of Hawaii Island, no tsunami threat Thursday (Feb 7)


Magnitude-4.6 earthquake southwest of the Island of Hawai‘i

The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded an offshore magnitude-4.6 earthquake southwest the Island of Hawai‘i on Thursday, February 7, at 9:07 a.m., HST.

The earthquake was centered about 84 km (52 miles) southwest of Ka Lae (South Point) at a depth of 27 km (17 mi). A map showing its location is posted on the HVO website at

Light shaking, with maximum Intensity of IV, has been reported across the Islands of Hawai‘i, Maui, and O‘ahu. At that intensity, damage to buildings or structures is not expected. The USGS “Did you feel it?” service ( received over 90 felt reports within two hours of the earthquake.

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 to Kīlauea or Mauna Loa volcanoes on the Island of Hawai‘i. According to the Pacific Tsunami Warning Center, there is no tsunami threat from this earthquake.
