A magnitude 4.2 earthquake shook Kilauea volcano Saturday evening, officials said.
The Pacific Tsunami Warning Center in Honolulu said no tsunami was generated from the quake, which struck at 5:26 p.m., but some areas may have experienced some shaking.
The U.S. Geological Survey said the quake was centered 27 miles south of Hilo and 12 miles southeast of Volcano at a depth of more than 3 miles.
Hawaiian Volcano Observatory officials said the quake was “part of the continuing adjustments beneath the south flank of Kilauea following the magnitude-6.9 earthquake that occurred on May 4, 2018.”
“The earthquakes have caused no detectable changes in activity at either Kilauea or Mauna Loa volcanoes,” they said in a news release.
HVO officials said that just before the Saturday earthquake, a magnitude-1.6 quake occurred deep beneath Kilauea’s southwest rift zone, “causing some initial confusion about the larger earthquake’s location.”
The USGS “Did you feel it?” self-reported web survey service received more than 100 reports within an hour of the larger earthquake.
