Volcanic Watch
Multiple Eruptions Active Across Pacific and South America Regions
Aoba Volcano, Vanuatu experienced a low-level eruption on June 2, 2026 at 2330Z, with volcanic ash plumes rising to approximately 10,000 feet (3,000 m) and moving southwest. The Volcanic Ash Advisory Center (VAAC) monitored the event closely.
Sabancaya Volcano, Peru continued explosive activity on June 3, 2026, with sporadic puff emissions reaching 23,000 feet (7,000 m) altitude. The VAAC Buenos Aires tracked the ash plume moving southward at 10 knots.
Mexico's Popocatépetl and Ecuador's Sangay remained notable activity centers. Popocatépetl emitted ash, gas, and vapor on June 3, 2026, while Sangay in Ecuador registered 356 seismically detected explosions with ash-and-gas plumes up to 800 m. Sangay maintained a Yellow Alert status with persistent thermal signals.
Kīlauea, Hawaii remains at Yellow Aviation Color Code following the end of lava fountain episode 46 at the summit. The volcano is currently not erupting, with the summit eruption in Halema'uma'u paused.
