Volcano Watch: U.S. Geological Survey updates Volcano Observatory Notice to Aviation alerts
Hawaiian Volcano Observatory on the Big Island will issue its first Volcano Observatory Notice to Aviation in the new format when the next Kīlauea fountaining episode begins — and the aviation community will get that information more quickly and effectively than ever before.
UPDATE: Episode 42 of ongoing summit eruption at Kīlauea volcano on Big Island ends after nearly 10 hours
An estimated 15 million cubic yards of lava erupted and covered about 50% of Halemaʻumaʻu Crater floor.
Volcano Watch: Handling the pressure; what gases trapped inside crystals tell us
Hawaiian Volcano Observatory scientists use tiny features within crystals in erupted lava to answer big questions about the underlying plumbing system at Kīlauea volcano on the Big Island.
Volcano Watch: When it rained rocks; tephra falls far and wide during Kīlauea Episode 41
Strong updrafts coupled with light winds blowing to the east and north sent lava fragments — called tephra — from those molten rock geysers over much of Puna, into Hilo and falling along the eastern edge of Kaʻū; learn more now!
Quakes swarm beneath Halemaʻumaʻu Crater within Kīlauea caldera on Big Island
It is yet to be determined if temblor swarms following Episode 40 of the ongoing episodic summit eruption that began Dec. 23, 2024, will impact lava fountaining activity at the surface.
Volcano Watch: Looking back at the 1959 episodic eruption of Kīlauea Iki
While the mid-20th century episodic eruption and current ongoing eruption within the summit caldera of Kīlauea volcano on the Big Island share similarities, there also are several differences.
Volcano Watch: Catching up on Kīlauea; 36 episodes and counting
Fountaining episodes during the past month and a half broke several records for this eruption, including the highest lava fountains, the most volume of lava erupted and the highest rate of lava effusion for this event, which has now lasted more than 10 months.
Volcano Watch: Moving magma — what happens after a dike intrudes a rift zone?
When magma moves into the rift zone of a Hawaiian volcano, there is understandably a lot of excitement and apprehension. How far will the magma go? Will it erupt? But even long after the activity stops — regardless of whether it erupts — the subsurface magma continues to have a noticeable impact on the landscape.
‘Kāholo’: Kīlauea definitely moved fast during Episode 6 of summit eruption
The most recent eruptive event of the Big Island volcano stopped at 12:36 p.m. Jan. 25, but Hawaiian Volcano Observatory says another episode could start within the next 1 to 2 days.
Lava fountains up to 200 feet again as Big Island’s Kīlauea awakens for fourth eruptive episode
Hawaiian Volcano Observatory reported the newest eruptive activity in the Big Island volcano’s summit caldera began at about 9:15 a.m. Wednesday, with a small lava flow exiting the north vent following low-level continuous lava spattering that started at about 5:40 a.m. from the same vent.
