The USGS Hawaiian Volcano Observatory recorded an earthquake swarm of more than 60 minor quakes that began around 1:17 a.m. on Wednesday.
The earthquakes are located about three miles north-northwest of Kilauea volcano’s summit, near Namakanipaio in Hawai’i Volcanoes National Park, at depths of one to three miles.
The seismic swarm has included more than 60 earthquakes, 14 of which were greater than magnitude 2.
The largest was a magnitude 3.2 earthquake at 6:55 a.m.
These small earthquakes have not been widely felt on the Island of Hawai’i.
The USGS "Did you feel it?" website received less than 10 felt reports in the first 12 hours following the onset of the swarm.
The earthquakes are located along the Ka’oiki Pali, a southeast-dipping normal fault near the boundary between Mauna Loa and Kilauea volcanoes.
This area has experienced episodic seismicity since the magnitude 6.6 Ka’oiki earthquake that occurred in November 1983.
Previous earthquake swarms have occurred along the Ka‘oiki seismic zone in 1990, 1993, 1997, and, most recently, in February-March 2006.
These swarms lasted from one day to several weeks, with earthquakes rarely exceeding magnitude 4.
