Pele’s show continues
Kilauea volcano has erupted more than 4.2 billion gallons of lava since its current summit eruption began Sept. 29.
Volcano Watch: What’s that rising from the lava lake?
The past year has seen fluctuating lava lakes, ephemeral lava fountains, craggy spires, and drifting “islands” reminiscent of pre-1924 Halemaʻumaʻu activity at the summit of Kilauea. The recent activity has USGS Hawaiian Volcano Observatory (HVO) scientists reflecting on prior observations and how they compare to recent activity.
Kilauea eruption enters second week
Kilauea volcano’s summit lava lake rose another 3 feet between Wednesday and Thursday, the Hawaiian Volcano Observatory reports.
Kilauea volcano eruption continues
Kilauea volcano’s summit lava lake continued to rise Wednesday, one week after the start of the most recent eruption within Halema‘uma‘u crater.
Kilauea volcano summit lava lake rising
Kilauea volcano’s summit lava lake rose by 3 feet between Monday and Tuesday, the Hawaiian Volcano Observatory reported Tuesday morning.
Kilauea alert level lowered
The Hawaiian Volcano Observatory Monday lowered Kilauea volcano’s alert level, noting less vigorous lava fountaining, reduced emissions and no indication of activity migrating outside the summit caldera.
Kilauea eruption persists: Lava lake continues to grow; emissions still elevated
Kilauea volcano’s summit eruption persisted for a fifth day Sunday with lava continuing to erupt from multiple vents within Halema‘uma‘u crater.
Volcano Watch: A new eruption in Halema‘uma‘u
Kilauea volcano is erupting again. Wednesday afternoon, lava returned to Kilauea’s summit within Hawaii Volcanoes National Park after a 4-month hiatus. A new line of fissures sliced through the solidified crust of the 2020–21 lava lake in Halema‘uma‘u at 3:21 p.m. HST.
Kilauea volcano eruption continues, lava lake growing within Halema’uma’u crater
The eruption within Halema’uma’u crater, at Kilauea volcano’s summit within Hawaii Volcanoes National Park continued Thursday morning.
Video: Lava fountaining inside Kilauea volcano
Lava is seen fountaining inside Kilauea volcano in Hawaii Volcanoes National Park on Wednesday in this video from the U.S. Geological Survey.
Kilauea once again erupting
Kilauea volcano is again erupting, the Hawaiian Volcano Observatory said Wednesday.
New HVO buildings would include research center at UH-Hilo, field station at HVNP
Hawaii Volcano Observatory’s scientist in charge said Tuesday progress is being made toward its new facilities.
Volcano Watch: Observations and impacts of the 2017-18 Vanuatu eruption
The Pacific is home to dozens of active volcanic systems including the massive Hawaiian shield volcanoes Kilauea and Mauna Loa. Most basaltic shield volcanoes in the Pacific are related to the hotspots that created the Hawaiian Islands and many of the Polynesian and Micronesian island chains.
Volcano Watch: How does HVO determine which regions are most threatened by lava flows?
Most residents of the Island of Hawaii live on one of four potentially active volcanoes and probably have wondered about the threat of lava flows at one time or another. Interestingly, determining future threats relies on knowledge of the past. The long-term likelihood of an area being invaded by lava in the future, is estimated in two different ways based on the history of lava flow activity.
Volcano Watch: The MILEAGE project — mapping Kilauea’s gas emissions
Large quantities of volcanic gases, such as carbon dioxide (CO2), sulfur dioxide (SO2), and hydrogen sulfide (H2S), are released into the atmosphere during volcanic eruptions. But even between eruptions, smaller amounts of the same gases continue to escape and can provide important clues about the current state of the volcano and the underlying magma. But to measure them, you first must identify where gas is coming from.
Volcano Watch: Eruption? Intrusion? What’s the difference?
We know that when a volcano erupts, molten red rock makes it to the surface, while during an intrusion it doesn’t. The difference between the two processes, if we depend on seismicity (earth shaking) or deformation (changes in ground surface) instrumentation, is not obvious. The events during the start of either are identical. But we can’t be certain that an intrusion will lead to an eruption.
Volcano Watch: New Kilauea summit intrusion draws comparison to past activity
Late Monday afternoon, earthquake activity picked up at Kilauea’s summit. At about 1:30 a.m. HST on Tuesday, that activity intensified, and it became clear that seismicity and increasing deformation were indicating a new intrusion of magma. The seismicity extended southward from Halema‘uma‘u crater, to an area south of the Kilauea caldera.
HVO detects renewed earthquake, deformation activity at Kilauea summit
Scientists with the U.S. Geological Survey’s Hawaiian Volcano Observatory said Friday morning that earthquake activity and ground deformation has resumed beneath the southern part of Kilauea summit caldera within Hawaii Volcanoes National Park.
