A light earthquake struck southwest of the Big Island this morning but did not pose a tsunami threat to the state.
The magnitude 4.6 quake struck at a depth of nearly 17 miles at 9:06 a.m., 82 miles south-southwest of Kailua-Kona, according to the U.S. Geological Survey. (The quake’s strength was downgraded slightly from the initial report of 4.8-magnitude.)
“No tsunami is expected. However, some areas may have experienced shaking,” the Pacific Tsunami Warning Center said in a bulletin.
The USGS “Did you feel it?” webpage survey received more than 90 responses within two hours of the earthquake, mostly from the Big Island.
Hawaiian Volcano Observatory officials said in a news release, “The depth, location, and recorded seismic waves of the earthquake suggest a source due to bending of the oceanic plate from the weight of the Hawaiian island chain, a common source for earthquakes in this area. Aftershocks are possible and could be felt.” The quake caused no detectable changes to Kilauea or Mauna Loa volcanoes, they added.
