Hawaiian Volcano Observatory Volcano Observatory

Summary: A magnitude-3.16 earthquake occurred 8 miles (12 km) south of Hōnaunau-Nāpōʻopoʻo on the Island of Hawaiʻi at a depth of 13 miles (21 km) below sea level at 8:34 a.m. HST on June 25, 2026.

On Thursday, June 25, 2026, at 8:34 a.m. HST, a magnitude-3.1 earthquake occurred 8 miles (12 km) south of Hōnaunau-Nāpōʻopoʻo on the Island of Hawaiʻi at a depth of 13 miles (21 km) below sea level. The earthquake had no apparent impact on Hualālai, Mauna Loa, or Kīlauea volcanoes. 

The earthquake today is likely an aftershock of the magnitude-6 earthquake that occurred on May 22. Like the magnitude-6 earthquake that occurred on May 22, this event is likely related to stress from the weight of the island on the underlying rigid mantle and was not directly related to volcanic processes or magma movement.  Light shaking was reported during this event, no damage is expected.  

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