A 4.7-magnitude earthquake struck Hawaii Island early Thursday morning, the U.S. Geological Survey said. Authorities confirmed there was no tsunami threat.
The quake happened at 12:52 a.m. south of Fern Forest, at a depth of four miles below sea level.
“Most earthquakes in this region are caused by abrupt motion of Kilauea volcano’s south flank, which moves to the southeast over the oceanic crust,” said the U.S. Geological Survey. “The location, depth, and waveforms recorded as part of today’s earthquake are consistent with slip along faults related to the south flank detachment fault.”
HVO said while there is no impact to either Kilauea or Mauna Loa volcano, geologists are continuing to monitor for any changes. They added that aftershocks are possible in the coming days to weeks.
