Volcano Watch — What do small earthquakes beneath Kīlauea summit mean for the ongoing eruption?
Kīlauea summit region has been remarkably quiet, from an earthquake standpoint, since the current eruption began on the night of Dec. 23, 2024. Since the end of episode 40 on the evening of Jan. 12, however, nearly a dozen small earthquake swarms have occurred involving earthquakes 1–2.5 miles beneath Halemaʻumaʻu and the summit caldera of Kīlauea.
Volcano Watch: Water in Kīlauea, and its role in its eruptions
Volcano Watch: Some of Kīlauea’s past explosive eruptions occurred when magma erupted through groundwater or through a lake in a summit crater.
Volcano Watch — Where does Kīlauea tephra go? The answer is blowin’ in the wind
The spectacular series of Kīlauea eruption episodes over the past six months has been remarkably safe for public viewing, but a simple change in the wind or brief vent collapse could cause dramatic changes in the hazards the volcano presents.
Volcano Watch — How to build a beach: Pohoiki growth over the years
The beach at Pohoiki grew rapidly in the year following the 2018 lower East Rift Zone eruption of Kīlauea and it has continued to evolve since then. The boat ramp was cut off from the ocean, and local warm springs formed in several low-lying areas.
Hirono, colleagues reintroduce volcano warning and monitoring legislation
In 2022, Hawaiʻi Island residents experienced an eruption from Maunaloa for the first time in nearly 40 years and they continue to see new eruptions from the summit of Kilauea. This program, first authorized in 2019, will help scientists at the USGS Hawaiian Volcano Observatory to continue improving their volcano monitoring and warning capabilities through expanded infrastructure and modernized technology.
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.
Volcano Watch: What’s shaking at the summit of Kīlauea
This past week, earthquakes and inflation near Kīlauea’s summit prompted temporary closures within Hawaiʻi Volcanoes National Park. What is happening beneath the surface at Kīlauea, and what does it mean for potential future eruptive activity?
Volcano Watch: Emergency managers and volcano observatories forge important partnerships
On the Island of Hawaiʻi, frequent eruptions foster a close relationship between the USGS Hawaiian Volcano Observatory and the Hawaiʻi County Civil Defense Agency. HVO monitors the active volcanoes and their associated hazards; HCCDA alerts and protects communities from impacts of volcanic events. This relationship, between volcano observatories and their emergency managers, was highlighted recently.
Volcano Watch: Kīlauea magma intrusion a textbook example of dike propagation
From Jan. 31 to Feb. 3, 2024, a magma intrusion into Kīlauea’s flank, southwest of the summit caldera, was the focus of attention at the USGS Hawaiian Volcano Observatory.
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.
Kīlauea eruption has stabilized, alert level dropped from warning to watch
The Keanakākoʻi viewing area is closed due to unsafe air quality. A plume of volcanic smoke contains sulfur dioxide, other gases and shards of volcanic glass that pose a significant risk, according to the Hawaiʻi Volcanoes National Park Service.
Volcano Watch: Reflections of recent eruptions
Kīlauea volcano began erupting within Halema‘uma‘u crater at the summit during the early morning of June 7. The eruption marks another in a series of recent eruptions that the Hawaiian Volcano Observatory has been able to successfully forecast.
Volcano Watch: The 2018 eruption of Kīlauea was big on a global scale
usands of residents. The voluminous lava flow had a major impact on the Island of Hawaiʻi, but how does it compare to other lava flow eruptions on Earth in recent history?
HVO: Kīlauea Under Sea Impacts Explored
The visible part of Kīlauea from the summit to the Lower East Rift Zone makes up only a small portion of the total volcano. Much of Kīlauea lies beneath the sea
Kīlauea Summit Collapse Releases Energy Equivalent to 5.4 Earthquake
The Hawaiian Volcano Observatory reports that a collapse event at Kīlauea summit occurred at 8 a.m. on Tuesday, July 31, 2018.
Explosive Collapse at Kīlauea Releases Energy Equivalent to 5.4 Quake
Hawaiian Volcano Observatory reports that a collapse/explosive event at Kīlauea summit occurred at 11:43 a.m. on Monday, July 16, 2018.
Explosive Collapse Event at Kīlauea Releases Energy Equivalent to 5.4 Earthquake
Hawaiian Volcano Observatory reports that a collapse/explosive event at Kilauea summit occurred at 9:21 a.m. on Monday, July 9, 2018. There was no tsunami generated from the seismic event that released energy equivalent to a 5.4 earthquake.
Ige Signs Request for Federal Individual Assistance in Wake of Volcanic Eruption
The county has estimated that since the recent onset of activity in May, the eruption has destroyed about 455 residential dwellings, 192 of which are primary residences.
Live Stream: Another Ash Plume Expected at Kīlauea Volcano Summit
Scientists with the USGS Hawaiian Volcano Observatory say there has been no explosive event since yesterday morning, but they do anticipate another one within the next few hours.
Lava Claims Hundreds of Homes Overnight, 7.7 Square Miles Covered
Hundreds of homes were claimed by lava in Kapoho Beach Lots and Vacationland overnight. HVO authorities report that most of Vacationland and all but the northern edge of Kapoho Beach Lots was inundated with lava by morning.
