Kilauea Volcano Builds Towards Explosive Eruption in Hawaii

The United States Geological Survey reports growing pressure at Kilauea volcano in Hawaii Volcanoes National Park on Hawaii's Big Island. Lava emerged from summit vents on Thursday night, January 22, 2026, as the volcano builds toward its next eruptive episode, potentially episode 41 of the year-long summit eruption. Scientists forecast this could begin between January 23 and 25, based on current inflationary tilt models showing a saw-tooth pattern of ground deformation. Each episode requires more pressurization, indicated by a black arrow on deformation graphs from the Hawaiian Volcano Observatory.

Elevated microseismicity persists, with earthquakes spread widely beneath the summit region, linked to migrating magmatic pressure. The observatory's information statement on January 23 details three possible outcomes. First, the eruption could continue from north and south vents in Halemaumau crater for an unforeseeable time, possibly shifting to continuous lava flow as vents break down. Second, a new vent might form in the summit region or upper southwest rift zone, signaled by tightly clustered earthquakes and shallow crack deformation, similar to episode 30 on August 6, 2025, when a fissure opened in Halemaumau's southwest wall. Third, and least likely, magma could migrate into the east rift zone, causing intrusion or eruption, with earthquakes moving southeast and summit deflation.

No changes in ground deformation suggest magma entering new areas yet, but inflation continues between earthquake swarms. The volcano alert level remains at watch, with close monitoring. Big Island Video News highlights this as part of ongoing summit activity, with all images courtesy of the USGS.

Elsewhere in the US, the USGS released an assessment of undiscovered resources in the Woodford and Barnett shales of the Permian Basin, spanning New Mexico and Texas. It estimates 28.3 trillion cubic feet of gas, enough for 10 months of national supply, and 1.6 billion barrels of oil, or 10 weeks' worth.

These events underscore patterns of volcanic inflation and resource potential in tectonically active US regions. Kilauea's episodic fountaining reveals magma reservoir dynamics, while Permian assessments highlight untapped shale plays amid energy demands. No major nationwide seismic shifts reported this week, but vigilance continues at key sites.
