Magnitude-4.5 earthquake south of Island of Hawaiʻi
The U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) recorded an offshore magnitude-4.5 earthquake south the Island of Hawaiʻi on Sunday, December 18, at 6:30 a.m., HST.
According to Brian Shiro, HVO's Seismic Network Manager, this earthquake was centered about 59 km (37 mi) south of Ka Lae (South Point) at a depth of 36.5 km (22.7 mi). A map showing its location is posted on the HVO website athttp://hvo.wr.usgs.gov/
The earthquake was felt on the Island of Hawaiʻi, with the the USGS "Did you feel it?" Web site (http://earthquake.usgs.gov/dy
Today’s earthquake occurred about 70 km (43 mi) southwest of Lō‘ihi, and was not caused by activity on that submarine volcano. 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 earthquake caused no detectable changes in Kīlauea Volcano's ongoing eruptions, on Mauna Loa, or at other active volcanoes on the Island of Hawaiʻi.
