The location and shaking intensity of a magnitude 4.1 earthquake Friday afternoon near Hawaii Volcanoes National Park.
Two earthquakes, one Thursday night and another Friday afternoon, rattled East Hawaii.
The Hawaiian Volcano Observatory recorded the first, a magnitude-4.6 temblor located beneath Kilauea Volcano's south flank, at 11:20 p.m. Thursday.
The earthquake was centered about 4.3 miles south of Pu'u 'O'o at a depth of approximately 4.2 miles.
Very light shaking was reported throughout the Big Island, Maui, and Lanai. The U.S. Geological Survey's "Did you feel it?" service received more than 725 felt reports within the first hour after the earthquake.
According to HVO seismologist Ashton Flinders, the earthquake had no apparent effect on Kilauea or Mauna Loa volcanoes.
"Aftershocks are possible and may be felt," Flinders said.
Kilauea's south flank has been the site of 20 earthquakes of magnitude-4.0 or greater during the past 20 years. Most are caused by abrupt motion of the volcano's south flank, which moves to the southeast over the oceanic crust.
This quake was likely an aftershock of the 2018 magnitude-6.9 earthquake as the volcano continues to settle.
