Kilauea Volcano Expected to Resume Lava Fountaining This Weekend as USGS Monitors Activity

The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) says the summit of Kilauea volcano on Hawaii’s Big Island has been erupting episodically since December 2024 and remains at an advisory alert level. Forecast models indicate a new lava‑fountaining episode could begin between July 25 and July 29, with no unusual activity reported along the East or Southwest rift zones.

At the same time, HVO’s annual GPS survey of nearby Mauna Loa shows the summit continues to inflate slowly. Twenty‑two benchmarks were measured this year, confirming a pattern of summit uplift and outward movement while the flanks shift slightly downward and away—about 2.9 inches of movement per year. Seismic activity and gas emissions remain low, and an eruption at Mauna Loa is not expected in the near term. The ongoing measurements help scientists detect subtle changes that could signal future unrest, keeping Hawaiian communities informed.
