A short-lived phreatomagmatic eruption took place at Taal's Main Crater at 21:18 UTC on July 6, 2021 (05:18 LT, July 7), generating a grayish plume that rose 300 m (985 feet) before drifting southeast. On July 4, sulfur dioxide (SO2) gas emission reached an…
A large explosive eruption took place at Azerbaijani Ignatiy Stone Bank mud volcano in the Caspian Sea, about 10 km (6.2 miles) from the Umid gas field and 30 km (18 miles) from the coast, at around 17:45 UTC (21:45 LT) on Sunday, July 4, 2021. This region has…
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…
A new powerful paroxysmal episode started at Etna's Southeast Crater, late July 1, 2021, and lasted approximately 120 minutes. This was the 5th paroxysm since June 25 and the first since June 28. Strombolian activity at the Southeast Crater resumed at 22:40 UTC…
New activity/unrest was reported for 3 volcanoes from June 23 to 29, 2021. During the same period, ongoing activity was reported for 11 volcanoes. New activity/unrest: Rincon de la Vieja, Costa Rica | Sarychev Peak, Matua Island (Russia) | Suwanosejima, Ryukyu…
A phreatomagmatic eruption took place at Taal volcano, Philippines at 07:16 UTC (15:16 LT) on July 1, 2021, generating a short-lived dark plume up to 1 km (3 300 feet). Anomalously high volcanic SO2 gas emission preceded the eruption, averaging 14 241 tonnes/day and…
An increase in volcanic activity was reported near the Fagradalsfjall eruption site in Southwest Iceland on Saturday, June 26, 2021. If the development continues, authorities said lava will flow sooner than expected over Suðurstrandarvegur road, a key road that…
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…
A powerful phreatic eruption took place at Rincon de la Vieja volcano, Costa Rica at 11:40 UTC (05:40 LT) on June 28, 2021. The event lasted about 3 minutes, ejecting dense column of gas and steam, with some amount of ash, up to 4.2 km (14 000 feet) above sea level,…
