Mānoa: Hawai‘i’s two most active volcanoes share a magma source
Using a nearly 200-year record of lava chemistry from Kīlauea and Maunaloa, earth scientists from the University of Hawaiʻi at Mānoa and colleagues revealed that Hawaiʻi’s two most active volcanoes share a source of magma within the Hawaiian plume.
Volcano Watch — Petrologists gather to discuss challenges and goals in understanding Kīlauea chemistry
In May of this year, a group of volcano geochemists and petrologists (scientists who study the chemistry, textures, and origins of volcanic rocks) met in Hilo to discuss how to improve our understanding of magma storage and evolution at Kīlauea.
Volcano Watch: A decade later, remembering the Pāhoa lava flow crisis
Over the past few years, eruptions of Kīlauea volcano on the Island of Hawai‘i have happened in remote regions and lava flows have not directly threatened communities. However, the approaching anniversary of a lava flow crisis a decade ago reminds us that eruptions on Kīlauea have the potential to cause damage and island-wide disruption.
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: Magnetics, magma and monitoring — new technology for old questions
Earth’s magnetic field surrounds us every second of the day, everywhere on the planet. Anyone who has picked up a pocket compass and seen the magnetic needle quickly align itself has seen the action of this ever-present invisible field. But can we harness the magnetic field to forecast volcanic activity? Emerging technology in the field of “quantum” science may aid us in doing so.
Volcano Watch: HVO and collaborators continue seismic survey across active volcanoes of Hawaiʻi
The permanent HVO seismic network consists of nearly 100 stations located across the island. HVO scientists use these stations to monitor the location and character of seismic activity, paying particular attention to signals that might herald migrating magma or potential eruptive activity.
Volcano Watch: STEM and suction solutions at HVO
Volcano Watch: Staff at HVO study volcanic processes and associated hazards in Hawaiʻi, with the emphasis and end goal of protecting life and property. The backbone of the observatory is the monitoring network, consisting of a diverse array of instruments located on the flanks of the volcanoes. These instruments relay data back to the observatory, providing information on the behavior of Hawaiʻi’s active volcanoes.
