USGS Volcano Notice - DOI-USGS-HVO-2026-06-24T18:52:34+00:00

On Wednesday, June 24, 8:29 a.m. HST, a magnitude-3.6 earthquake occurred 9 mi (14 km) south of the village of Volcano on the Island of Hawaiʻi at a depth of 5 mi (7 km) below sea level. The earthquake had no apparent impact on either Mauna Loa or Kīlauea volcanoes. 

Most earthquakes in this region are caused by motion of Kīlauea volcano's south flank, which moves to the southeast over the oceanic crust. The location, depth, and waveforms recorded as part of today's earthquake are consistent with slip along the south flank. This earthquake is not directly related to the ongoing eruptive activity on Kīlauea volcano.

The USGS Hawaiian Volcano Observatory continues to monitor Hawaiian volcanoes for any changes.
