(BIVN) – A magnitude-5.3 earthquake that rattled Hawaii Island on Thursday morning has been reviewed by the U.S. Geological Survey’s Hawaiian Volcano Observatory.
HVO issued a media release on the quake that was recorded beneath Kīlauea Volcano’s south flank at at 7:01 a.m. HST.
The earthquake, which was widely felt on the Island of Hawai‘i, was located about 11.2 miles southeast of Volcano at a depth of 5 miles, scientists report.
The USGS “Did you feel it?” website received almost 800 felt reports within the first hour of the earthquake. HVO said the maximum intensity of shaking reported by Island of Hawai‘i residents was V on the Mercalli Intensity Scale, indicating moderate shaking.
The Pacific Tsunami Warning Center reported there is no tsunami threat from this earthquake shortly after it occurred.
“As of this writing, Hawaiʻi County Civil Defense has not received any reports of damage,” HVO said. Civil defense issued an alert on the earthquake roughly ten minutes after it struck.
There have been at least 15 aftershocks following this morning’s magnitude-5.3 earthquake, the scientists say.
“Kīlauea’s south flank has been the site of 29 earthquakes of magnitude-4.0 or greater during the past 25 years,” the HVO media release explains. “Most are caused by abrupt motion of the volcano’s south flank, which moves to the southeast over the oceanic crust as a result of magma being injected into the East Rift Zone and long term settling of the volcano. The location and depth for today’s earthquake are consistent with slip along or above this south flank fault.”
According to HVO Scientist-in-Charge Christina Neal the earthquake had no apparent effect on Kīlauea Volcano’s ongoing eruptions. “HVO monitoring networks have not detected any significant changes in activity at the summit or along the rift zones of Kīlauea or at other Hawaiian volcanoes resulting from the earthquake,” Neal said.
