Volcano Watch: Earthquakes and volcanoes, a recipe for preparedness
Feeling occasional earthquakes is part of the experience of living in the State of Hawaiʻi, especially on the Island of Hawai‘i. The vast majority of felt earthquakes are small, but the less common large earthquakes can be damaging, so it is important to be prepared.
No tsunami threat after two “moderate” Mauna Loa earthquakes, 4.6 and 5.0 M
“The two earthquakes occurred within 24 seconds of each other creating shaking of longer duration and possibly greater intensity than either of the earthquakes would have created on their own,” according to an HVO information statement.
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.

Wednesday afternoon, Sept. 29, lava returned to Kīlauea’s summit within Hawaiʻi Volcanoes National Park after a four-month hiatus. A new line of fissures sliced through the solidified crust of the 2020–21 lava lake in Halemaʻumaʻu.
BREAKING: Kīlauea is Now Erupting
Kīlauea volcano is erupting. At approximately 3:20 p.m. HST on Wednesday, Sept. 29, 2021, the USGS Hawaiian Volcano Observatory detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park.
Kīlauea Advisory Level Remains Yellow: 80 Small Earthquakes Recorded in 24 Hours
“The rate of ground deformation beneath the south part of Kīlauea summit region, within Hawaiʻi Volcanoes National Park, began increasing again on the evening of Aug. 26 and continues at this time. These observations suggest that magma is continuing to be supplied to the ongoing intrusion,” according to the HVO.
