The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.1 earthquake east of the Island of Hawaiʻi on Friday, Aug. 18, 2017, at 8:35 p.m. HST.

The earthquake was located 66 miles northeast of Hawaiian Beaches and 73 miles east-northeast of Hilo, Hawaiʻi, at a depth of 18 miles.

The USGS ‘Did you feel it?’ website received almost 100 felt reports within an hour of the earthquake. The USGS ShakeMap was III on the Modified Mercalli Intensity Scale, indicating light shaking.

According to HVO Seismic Network Manager Brian Shiro, the earthquake was likely due to bending of the oceanic plate from the weight of the island and poses no significant hazard.

The Pacific Tsunami Warning Center reported that the earthquake had no apparent effect on Kīlauea Volcano’s ongoing eruptions.
