M3.6 earthquake consistent with slip along Kīlauea volcano’s south flank
A magnitude-3.6 earthquake occurred 9 miles south of the village of Volcano on the Island of Hawaiʻi at 8:29 a.m. on Wednesday, June 24, 2026. The quake occurred at a depth of 5 miles below sea level, according to the Hawaiian Volcano Observatory.
Early morning earthquake on on Hawaiʻi Island attributed to seismic swarm under the Pāhala area
“This earthquake is part of the seismic swarm under the Pāhala area, which has been going on since 2019,” according to the HVO. “Earthquakes in this region have been observed at least as far back as the 1960s.”
Volcano Watch — Remembering the 1926 Maunaloa eruption a century later
April marked the 100-year anniversary of Mauna Loa’s 1926 Southwest Rift Zone eruption. This eruption is most remembered for the destruction of Ho‘ōpūloa village, a few miles north of Miloliʻi Bay. It also marks the first known instance of aerial photography of an advancing Hawaiian lava flow, and well-organized police-led eruption crowd management.
No tsunami expected after 4.2 quake off Kaʻū Coast of Hawaiʻi Island
There is no tsunami expected after a 4.2 earthquake reported at 5:16 p.m. on Thursday, March 12, 2026, located off the Kaʻū Coast of Hawaiʻi Island.
Third earthquake swarm at the summit of Kīlauea reported since the end of episode 40
Most of the earthquakes are volcano-tectonic earthquakes that accompany crack opening due to magmatic pressure, according to the Hawaiian Volcano Observatory.
No tsunami threat after 4.0 earthquake off Kaʻū Coast of the Big Island
There is no tsunami expected after a preliminary magnitude 4.0 earthquake reported at 9:38 a.m. on Tuesday, May 20, 2025 off the Kaʻū Coast of the Big Island. The Pacific Tsunami Warning Center issued an information statement saying there is no tsunami expected, however some areas may have experienced shaking.
Volcano Watch — What’s shaking? Earthquake alerts explained
When an earthquake strikes in Hawaiʻi, there are three agencies that analyze the earthquake for its location and magnitude. Typically, the earliest earthquake information will be from automated solutions generated by computer algorithms from PTWC and HVO. Human analysts from HVO and NEIC will then review the magnitude-2.5 or larger earthquakes to get a more accurate magnitude and location.
More than 70 earthquakes in seismic swarm around Kamaʻehuakanaloa, formerly Lōʻihi Seamount
The HVO issued as status update saying there have been over 70 earthquakes so far in this swarm, with 32 events greater than magnitude 2 and two events greater than magnitude 4. The largest earthquake has been a magnitude-4.3 event that occurred Saturday at 12:05 p.m. HST, at a depth of 5.8 km (3.6 mi) below sea level and 4.8 km (3.0 mi) below the volcano’s summit.
