Researchers at NASA’s Jet Propulsion Laboratory in Southern California identified what triggers large-scale volcanic eruptions and the conditions that lead to them. Using data from the 2018 Kilauea eruption in Hawaii– its largest volcanic eruption in over 200…
A small swarm of shallow seismicity, that began at 11:00 UTC on March 18, 2021, is occurring beneath the upper Ka‘ōiki seismic zone, under Mauna Loa’s southeast flank and northwest of Kīlauea's summit, Hawaii. Mauna Loa Volcano is not erupting;…
Lava activity at Hawai'ian Kilauea volcano is confined to Halemaʻumaʻu with lava erupting from vents on the northwest side of the crater, the Hawaiian Volcano Observatory (HVO) reported at 19:11 UTC on January 5, 2021. Early January 5 (UTC), the lava lake was…
Seismic activity increased on Mauna Loa's northwest flank on December 4, 2020, with M4.1 earthquake and clusters of small, shallow earthquakes occurring closely in time and location. The volcano is not erupting but the rates of deformation and seismicity have…
USGS seismologists have detected deep long-period earthquakes beneath the dormant Mauna Kea volcano in Hawaii at depths of about 20 to 25 km (12 to 15 miles) occurring with surprising regularity every 7 to 12 minutes. While low-frequency earthquakes are not unusual,…
New research reveals that Hawaii's Pūhāhonu volcano is the largest and hottest shield volcano on Earth, although it is barely visible as only a portion of its tip is exposed above the seafloor. Pūhāhonu, a Hawaiian word which means "turtle surfacing for…
The USGS Hawaii Volcano Observatory (HVO) reported increased seismic activity at the submarine Lōʻihi volcano in Hawaii from May 11 to 12, 2020. More than 100 earthquakes were detected, but USGS noted that there is no indication that a submarine eruption has…
Earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels over the past several months, forcing the Hawaiian Volcano Observatory to raise the Alert Level to Advisory and the Aviation Color Code to Yellow. All communities…
Activity at Hawaiian Mauna Loa volcano has risen to levels comparable to a higher period of activity between 2014 and 2017, HVO scientists said. The last eruption at the volcano took place in 1984. While there is no cause for alarm, those signs of higher activity…
While Kīlauea Volcano in Hawaii is not erupting at the moment and rates of seismicity, deformation, and gas release have not changed significantly over the past week, deformation signals are consistent with refilling of the middle East Rift Zone (ERZ) and hazards…
