Some residents on the Big Island of Hawaii were shaken by a magnitude 4.4 earthquake early Saturday.
The U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) says the earthquake was recorded at 4:37 a.m. beneath Kilauea volcano's south flank located in the Pûlama Pali area about 7 miles west of Kalapana and 4 miles southeast of the Pu`u O'o crater, at a depth of 6 miles.
The earthquake was widely felt on the Big Island. The USGS "Did you feel it?" Web site received 160 felt reports within the first hour of the earthquake.
There were no aftershocks following the magnitude-4.4 earthquake this morning.
HVO says that the Pûlama Pali of Kîlauea's south flank has been the site of 23 earthquakes of magnitude-4.0 or greater during the past 50 years, with 8 since 1983. Most are caused by abrupt motion of the volcano's south flank moving southeast over the ocean crust at an average rate of 2.6 inches per year as a result of magma injected into the rift zone.
No tsunami was generated.
The earthquake did not have any apparent effect on Kilauea's ongoing eruption.
