USGS HVO Press Release — Magnitude-5.0 earthquake southeast of Volcano, Island of Hawai‘i
The U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) recorded a magnitude-5.0 earthquake on Thursday, May 3, 2018, at approximately 10:31 a.m. HST.
The earthquake was located about 7 km (4.3 mi) southeast of Volcano, on the Island of Hawai‘i, at a depth of 6.9 km (4.3 mi). A map showing the location of the earthquake is posted on HVO's website at https://volcanoes.usgs.gov/observatories/hvo/hvo_earthquakes.html.
The USGS "Did you feel it?" website (https://earthquake.usgs.gov/dyfi/) received over 500 felt reports from around the Island of Hawai‘i within an hour after the quake. The maximum intensity of shaking was recorded as VI on the Mercalli Intensity Scale, indicating strong shaking at the earthquake's epicenter. For more information see the USGS ShakeMap at https://earthquake.usgs.gov/earthquakes/eventpage/hv70112126#shakemap.
"It appears that ground shaking from the earthquake caused rockfalls in the Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's East Rift Zone, which resulted in a short-lived plume of reddish ash rising above the cone," said Tina Neal, HVO Scientist-in-Charge. No other changes at Kīlauea have been observed, but HVO scientists are closely monitoring the data.
According to the Pacific Tsunami Warning Center (PTWC) no tsunami was generated by the earthquake.
