Volcano Watch — One year of Kīlauea’s episodic summit fountaining: highlighting the hazards
On Dec, 23, 2024, a unique eruption began in Kīlauea’s Halemaʻumaʻu crater, with a style of activity not seen for nearly 40 years. The eruption, characterized by high lava-fountaining episodes, has continued for nearly a year. Hawaiʻi Volcanoes National Park visitors see remarkable views, but the latest episode reminds us how quickly hazards associated with this dynamic activity can change.
Volcano Watch: Kīlauea’s continuing summit eruption
Kīlauea summit has shown little net change in pressurization since the eruption began Dec. 23, 2024, indicating the summit has been in some level of equilibrium. As long as that equilibrium is maintained, the episodic eruption at the summit is likely to continue.
Volcano Watch: The nose knows, and so does HVO gas instrumentation…eventually
It was a dark and stormy night… and the volcano had a secret.
Volcano Watch – Recent intrusions follow pattern of previous events
An intrusion is an injection of magma into rock, that causes ground deformation and seismicity but does not result in an eruption.
Volcano Watch: Hualālai’s Wahapele eruption: cone-building, explosive phreatic activity, and lava flows
While our attention is generally drawn to the Island of Hawai‘i’s most active volcanoes, Kīlauea and Mauna Loa, it is also important to keep watch on the Island of Hawai‘i’s third-most active volcano, Hualālai, which underlies the most populated areas of Kailua-Kona and the central Kona coast.
Volcano Watch: What is a volcano?
In one dictionary definition, a volcano is a vent in the earth’s crust through which rock or lava is ejected. In another, a volcano is a cone-shaped hill or mountain built around a vent. Most volcanologists find both of these dictionary definitions somewhat lacking.
Volcano Watch — Kīlauea’s dynamic landscape: Reflections on the past four years
May 3rd marked the 4th anniversary of the start of Kīlauea’s historic 2018 eruption that covered much of lower Puna with lava flows and dropped the crater floor of the summit.
Volcano Watch – Something new from something old: A new Geologic Map of the State of Hawaiʻi
The original purpose of geologic mapping in Hawaiʻi was to understand the distribution of groundwater and soils to support agriculture. But as geologic maps have been developed over time, they’ve provided basic information on how the Hawaiian Islands evolved, the workings of individual volcanoes, and the relative degree of long-term hazards posed.
Kīlauea
Lava continues to erupt from two vents at the Kīlauea volcano on Hawai’i Island. One of the vents is located along the floor and one is located in the western wall of Halemaʻumaʻu crater.
Kīlauea Eruption Continues with Multiple Vents Along the Crater Floor
Kīlauea volcano continues to erupt, with multiple active vents along the floor and western wall of Halemaʻumaʻu crater.
Volcano Watch: Kīlauea’s Other Rift Zone —Young Activity in the Southwest Rift Zone
The newly enlarged Halemaʻumaʻu Crater is currently filling with lava from an eruption that began in December of 2020. The frequent summit and East Rift Zone eruptions often seem to overshadow Kīlauea’s Southwest Rift Zone, which extends southwest from Halemaʻumaʻu to the coast about 5 km (3 mi) southeast of Pāhala.
