A new eruptive episode started at Kīlauea’s Halemaʻumaʻu crater at 13:11 UTC (03:11 HST) on September 19, 2025, producing lava fountains over 150 m (500 feet) and a volcanic plume up to 3 000 m (10 000 feet) high. The eruption remains confined to the summit caldera within Hawaiʻi Volcanoes National Park.
The highest levels of volcanic sulfur dioxide or SO2 gas emission were recorded today, July 4, 2021, at an average of 22 628 tonnes/day — representing the highest ever recorded over Taal, PHIVOLCS reports. The previous record was set on June 28, 2021, with 14 326…
Volcanic smog (vog) is a visible haze comprised of gas and an aerosol of tiny particles and acidic droplets created when sulfur dioxide (SO2) and other gases emitted from a volcano chemically interact with sunlight and atmospheric oxygen, moisture, and dust. Called…
High levels of volcanic sulfur dioxide or SO2 gas emissions and tall, steam-rich plumes have continued to be produced from the Taal Main Crater since this past weekend, PHIVOLCS reported on Tuesday, June 29, 2021. Unprecedented SO2 emissions were recorded on June…
Volcanic smog or vog has been observed over Taal Caldera resulting from continued volcanic SO2 gas emission from the Main Crater. High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose as much as 3 km (9 842 feet) high have been…
High sulfur dioxide emissions and other gasses and particles released during ongoing eruption of Hawaiian Kilauea volcano have reached Micronesia, some 4 000 km (2 500 miles) west of the volcano, forcing authorities to issue health alerts. The latest NOAA HYSPLIT…
