COURTESY USGS A swarm of small earthquakes struck Kama’ehuakanaloa Volcano, formerly called Lo’ihi Seamount, off the southeast coast of Hawaii Island today.
Dozens of small earthquakes — the largest at a magnitude of 4.3 — rumbled along the Kama’ehuakanaloa submarine volcano southeast of Hawaii island Friday evening and today, according to the U.S. Geological Survey.
The largest earthquake occurred at about 12:05 a.m. at a depth of about 5.8 kilometers under the sea and about 5 kilometers below the summit of the volcano. It was centered about 50 kilometers east-southeast of Naalehu and 90 kilometers southwest of Hilo.
Kama’ehuakanaloa Volcano, formerly called Lo’ihi Seamount, “entered a period of increased seismic unrest around 6 p.m. Friday,” USGS scientists said today.
“Although seismicity decreased slightly around midnight, earthquakes still remain above background levels today. There have been more than 70 earthquakes in this swarm to date, with 32 events greater than magnitude 2 and two events greater than magnitude 4,” according to a USGS summary.
The USGS has received only one report so far of the larger volcano being felt on Hawaii Island, scientists said.
“Increased seismicity at Kama’ehuakanaloa continues, but is not expected to impact other volcanoes or any infrastructure on Hawaii Island,” USGS officials said. Eruptive activity at the undersea volcano will not impact Big Island residents, they said.
