UPDATE: Earthquake that struck off Kona Coast revised back to magnitude-4.6; more than 800 ‘Felt Reports’ received

This story was updated at 7:45 p.m. Tuesday, June 2, 2026.

An earthquake originally reported as a magnitude-4.6 and then revised to a magnitude-5.2 that struck just before 6 p.m. Tuesday, June 2, off the Kona Coast of the Big Island was once again revised to a magnitude-4.6 quake by U.S. Geological Survey.

Pacific Tsunami Warning Center reports there is no tsunami expected following the quake.

Hawaiian Volcano Observatory said in an information statement that the earthquake struck at 5:58 p.m. Tuesday, June 2, nearly 4 miles west-northwest of the Kahaluʻu-Keauhou area on the west side of the island at a depth of about 21 miles below sea level.

It had no apparent impact on Hualālai, Mauna Loa or Kīlauea volcanoes.

More than 121 “Felt Reports” were made from around the Big Island and Maui within the first hour following the quake. A total of 816 “Did You Feel It?” responses had been received by 7:43 p.m. Tuesday by U.S. Geological Survey.

Those who felt the earthquake are encouraged to report it online to U.S. Geological Survey.

“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,” said Hawaiian Volcano Observatory in its information statement.

That’s the same cause the observatory gave for the major magnitude-6.0 temblor that struck shortly before 10 p.m. Friday, May 22, in South Kona that destroyed several homes and caused damages to hundreds more.

These earthquakes are generated below the volcanoes and the ocean crust in the upper mantle beneath the Hawaiian Islands.

The Tuesday night earthquake was similar in origin but unrelated to the South Kona magnitude-6.0.

“Like the magnitude-6.0 earthquake that occurred 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,” Hawaiian Volcano Observatory said.

Moderate shaking was reported by community members while instruments classified it as light shaking. Hawaiian Volcano Observatory said there could be very light damage to buildings or infrastructure based on the earthquake’s intensity.

Several people began reporting the temblor on social media within minutes after it struck.

At least two asked if it was an aftershock from the major magnitude-6.0 that struck shortly before 10 p.m. Friday, May 22, south of about 8 miles south of Hōnaunau-Nāpōʻopoʻo in South Kona on the west side of the Big Island.

“Earthquake just now on Big Island,” posted Alyssa Lee at about 6:07 p.m. Tuesday in Keaʻau. “Not as big as the last one, but a little shaker.”

Other reports on social media were made within the first half an hour after by people in Hilo, Pepe‘ekeo, Waimea and elsewhere around the island.

“Rock and Roll again!” posted Healani Germano Ome at 6:01 p.m. Tuesday in the Waimea Insiders group on Facebook. “Did you feel it?!?!”

Aftershocks are possible.

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