Heightened seismic unrest observed at Kamaʻehuakanaloa over six hour period
Kamaʻehuakanaloa volcano (formerly known as the Lōʻihi Seamount), offshore to the southeast of the Island of Hawaiʻi, entered a period of heightened seismic unrest around 2 a.m. HST on Monday, Jan. 21. Seismicity ceased by 8 a.m. HST and a continuation of earthquake swarm activity at this time seems unlikely, according to an update from the Hawaiian Volcano Observatory.
4.3 magnitude Big Island earthquake is part of ongoing seismic swarm in Pāhala
A magnitude-4.3 earthquake, reported at 11:04 p.m. on Sunday, Dec. 29, occurred 1 mile west-southwest of Pāhala on the Island of Hawaiʻi at a depth of 19 miles below sea level.

4.8 earthquake on Hawaiʻi Island part of ongoing swarm beneath Pāhala
A 4.8 magnitude earthquake reported overnight on the Big Island of Hawaiʻi, was part of an ongoing swarm of deep seismicity that has been occurring beneath the Pāhala area since 2019, according to scientists with the Hawaiian Volcano Observatory.
Unrest escalates at Kīlauea; more than 500 earthquakes rock upper East Rift Zone
While there are no signs of an imminent eruption, the largest of these earthquakes were four magnitude-3.0 events near the intersection between Chain of Craters Road and Hilina Pali Road in Hawaiʻi Volcanoes National Park.
4.1 earthquake on Big Island is part of a seismic swarm under Pāhala; no apparent impact to Maunaloa or Kīlauea
A preliminary magnitude-4.1 earthquake occurred 9 miles east-southeast of Nāʻālehu on the Island of Hawaiʻi at around 1:43 p.m. on Friday, June 14, 2024. Scientists with the Hawaiian Volcano Observatory issued an information statement saying the earthquake is part of the seismic swarm under the Pāhala area, which has been going on since 2019. Earthquakes in this region have been observed at least as far back as the 1960s.
Volcano Watch: Appreciating contributions of ʻŌlelo Hawaiʻi to volcanology
February is Mahina ʻŌlelo Hawaiʻi, Hawaiian Language Month, and an opportunity to appreciate the value that the Native Hawaiian language has provided to volcanology, especially in Hawaiʻi nei.
Kīlauea volcano alert level is at Watch/Orange as seismic swarm continues
Scientists continue to monitor Kīlauea as an ongoing seismic swarm rumbles beneath the Koaʻe fault zone, 5-8 miles southwest of the caldera.
Scientists report ‘elevated unrest’ near Kīlauea summit
Scientists with the Hawaiian Volcano Observatory issued an information statement on Monday saying there has been a 24 hour period of “elevated unrest” at Kīlauea.
4.0 earthquake is not related to Mauna Loa activity; Part of a seismic swarm under Pāhala
A 4.0 magnitude earthquake reported at 3:27 a.m. on Tuesday, Nov. 29, was located 6 miles east of Pāhala at a depth of 20 miles.
Volcano Watch: Recent events at Mauna Loa remind us to be prepared for quick changes
A noticeable seismic swarm occurred from late January through mid-April 2021 and was accompanied by changes by ground surface tilt recorded by a summit tiltmeter. This was an unprecedented observation that indicated magma had been getting closer to the surface. Another short swarm and tilt event was observed in early August 2022.
4.5 Hawaiʻi earthquake is part of seismic swarm, no apparent impact on volcanoes
A magnitude-4.5 earthquake reported at around 12:43 p.m. on Tuesday, Sept. 27, 2022, is part of a seismic swarm under the Pāhala area that has been ongoing since 2019.
More than 38 earthquakes in seismic swarm beneath summit of Mauna Loa
An estimated 38 small earthquakes have occurred beneath the summit of Mauna Loa volcano since 2 a.m. on Friday, Sept. 23, 2022. The US Geological Survey’s Hawaiian Volcano Observatory reports that the quakes are part of a small seismic swarm beneath the summit caldera region.
Swarm of 50 small earthquakes occur beneath Kīlauea summit over three hours
A seismic swarm of approximately 50 small earthquakes was reported over a three hour period, beginning at around 3 p.m. on Tuesday, Sept. 20, 2022, beneath the Kīlauea summit, according to the USGS Hawaiian Volcano Observatory.
4.2 Hawaiʻi Island earthquake part of seismic swarm under the Pāhala area
There was no tsunami threat from a 4.2 magnitude earthquake reported overnight in the Pāhala area of the Kīlauea Volcano on Hawaiʻi Island. The quake occurred at 2:04 a.m. on Thursday, Sept. 8, 2022, about 6 miles ENE of Pāhala, at a depth of 21 miles below sea level.
4.0 Hawaiʻi Island earthquake is part of seismic swarm that began in 2019
There was no tsunami threat to Hawaiʻi following a 4.0 earthquake reported at 3:20 p.m. on Monday, Sept. 5, 2022. The earthquake was located about 7 miles east-northeast of Pāhala on Hawaiʻi Island, at a depth of 20 miles below sea level.
4.0 earthquake at Kīlauea is part of seismic swarm under Pāhala, no threat
A 4.0 earthquake reported at 7:11 p.m. on Monday, Aug. 22, about six miles east of Pāhala on Hawaiʻi Island, is believed to be part of a seismic swarm which has been going on since 2019, according to Hawaiian Volcano Observatory scientists.
Two 4+ earthquakes overnight on Hawaiʻi Island, likely part of “seismic swarm”
Two 4+ magnitude earthquakes that occurred within seconds of each other overnight on Hawaiʻi Island, were likely part of the seismic swarm under the Pāhala area, which has been going on since 2019, scientists say.
HVO: 4.0 earthquake on Hawaiʻi Island ‘appears to be part of a seismic swarm’
An early morning 4.0 earthquake in the Pāhala area of Hawaiʻi Island “appears to be part of a seismic swarm,” according to US Geological Survey’s Hawaiian Volcano Observatory seismologist Jefferson Chang.
4.1 Tremor is Part of Earthquake Swarm Beneath Kīlauea’s Lower SW Rift Zone
A 4.1 magnitude earthquake located east of Pāhala at 2:02 a.m. HST on Wednesday, Aug. 18, is believed to be part of an ongoing seismic swarm under the Pāhala area, which started in August 2019.
Seismic Swarm Continues: More than 100 Earthquakes Recorded
Scientists say it’s likely that high rates of seismicity could continue for several days. Officials say the earthquake swarm has not caused any obvious changes in Kilauea’s magma plumbing system or ongoing eruptions; but that the magnitude 4.3 quake did cause a small rockfall in the active vent located within Halema‘uma‘u Crater at the summit of Kilauea.
