4.6-Magnitude Earthquake Shakes Hawaii’s Big Island Near Kīlauea — No Tsunami or Damage Reported

4.6-Magnitude Earthquake Shakes Hawaii’s Big Island Near Kīlauea — No Tsunami or Damage Reported

A magnitude-4.6 earthquake struck the southeastern side of Hawaii’s Big Island just before midnight, centered on the south flank of Kīlauea at a depth of about three miles (5 km). Officials said no tsunami warning was issued and no damage has been reported. Preliminary USGS analysis indicates the tremor is not clearly tied to recent eruptions, though it occurred roughly 10 minutes after the end of episode 37 lava fountaining. Authorities continue to monitor conditions and will provide updates as needed.

A magnitude 4.6 earthquake struck the southeastern side of Hawaii’s Big Island just before midnight local time on Wednesday, the U.S. Geological Survey (USGS) reported.

The Hawaii Emergency Management Agency located the event on the south flank of Kīlauea and said no tsunami was expected.

The USGS estimated the quake's depth at about three miles (roughly 5 kilometers) beneath the surface. Preliminary analysis indicates the seismic event does not appear to be directly linked to Kīlauea’s recent eruptions.

USGS: The earthquake had no apparent impact on either Mauna Loa or Kīlauea. The event followed the end of episode 37 lava fountaining on Kīlauea by about 10 minutes but does not appear to be directly related to the eruption. Most earthquakes in this region are caused by movement of Kīlauea's south flank.

There have been no reports of damage or injuries. Officials are continuing to monitor seismic and volcanic activity and advise residents to follow updates from local authorities.
