On Tuesday, June 2, 2026, at 5:58 p.m. HST, a magnitude-4.6 earthquake occurred 4 miles (6 km) west-northwest of Kahaluu-Keauhou on the Island of Hawaiʻi at a depth of 21 miles (34 km) below sea level. The earthquake had no apparent impact on Hualālai, Mauna Loa, or Kīlauea volcanoes. 

The depth, location, and recorded seismic waves of the earthquake suggest a source due to bending of the Pacific plate from the weight of the Hawaiian island chain, a common source for earthquakes in this area. These earthquakes are generated below the volcanoes and the ocean crust in the upper mantle beneath the Hawaiian Islands. The earthquake today is similar in origin but unrelated to the magnitude-6 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.  Moderate shaking was reported during this event, which could cause light damage.  

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