Volcanic activity saw notable shifts today: the Philippines’ Mayon intensified, Indonesia’s Semeru was raised to Level 3, Colombia’s Purace dropped to Yellow, and ash from Guatemala’s Fuego reached nearby towns. Elsewhere, regular explosions persisted at Sabancaya and Santa Maria, while continuous tremor continued at Taal. Lewotolok’s activity eased even as monitoring still detected numerous explosions.

Indonesia
Semeru (Level 3 – Standby) was elevated after monitoring registered 119 explosions and several rockfalls. Eruptive activity at Lewotolok eased, though 254 explosions were still detected. Low plumes and rockfalls accompanied ongoing activity at Ibu, Merapi, Marapi, and Dukono. Unrest persisted at several others on Levels 2–3, including Raung and Kerinci.

Philippines
At Mayon (Level 3), lava effusion, dome-collapse rockfalls, and minor Strombolian bursts were accompanied by frequent PDC-related seismic signals. Plumes at Kanlaon rose to 800 m, while low-level unrest persisted at Taal with plumes to 300 m and continuous tremor since 21 January.

Mexico
Popocatepetl (Yellow Phase 2) produced gas-and-steam emissions and a M2.4 VT earthquake.

South America
Purace stepped down to Yellow as ash emissions and seismic energy declined and a crater thermal anomaly faded. Peru’s Sabancaya sent ash-and-gas up to 1 km with a handful of quakes; in Ecuador, activity increased at Sangay while eruption at Reventador continued.

Other
Guatemala’s Fuego lofted ash to about 700 m and produced ashfall in San Pedro Yepocapa, Panimache Uno and Dos, Morelia, and Santa Sofia. Nearby Santa Maria saw up to four explosions per hour with incandescent rockfalls, and weak gas rose from Pacaya. In Costa Rica, Poas featured a largely dry Laguna Caliente with low tremor and minor fumaroles, while Rincon de la Vieja and Turrialba remained at Level 2; Irazu stayed calm.

Explosive Andean and Indonesian volcanoes stood out today, led by Sangay and Fuego, while Mayon’s effusion persisted in the Philippines. Notable shifts from yesterday include Semeru’s alert lowered to Level 2, Poas now Aviation Yellow, Piton de la Fournaise listed as a continuing eruption, and ash reported at Sangay and Purace.

Indonesia
Lewotolok produced 648 seismically detected explosions. Semeru recorded 121 explosions and four rockfalls (Level 2 – Alert). Ibu registered 124 explosions with low gas plumes, while Merapi sent two hot rockfalls up to 1.8 km. Low plumes persisted at Dukono and activity at Marapi stayed modest; several other Indonesian volcanoes remained in unrest, and Tangkuban Parahu held at Level 1 – Normal.

Philippines
Mayon displayed lava effusion and dome growth with minor Strombolian bursts; 317 rockfalls and seismically detected pyroclastic density currents were noted (Alert Level 3). Kanlaon emitted plumes to 300 m. Taal produced plumes to 450 m and experienced a continuous tremor episode beginning at 0900 (Alert Level 1).

Mexico
Popocatepetl continued with gas-and-steam emissions (Yellow Alert – Phase 2).

South America
In Ecuador, Sangay generated 374 explosions, ash-and-gas plumes to 1.5 km, and a small SE-flank lava flow confined near the crater, while Reventador produced 94 explosions with ash to 1 km and thermal anomalies. Peru’s Sabancaya sent ash-and-gas plumes to 1 km alongside a dozen internal earthquakes, and Colombia’s Purace produced a single ash emission to 300 m amid ongoing tremor and degassing.

Africa
Piton de la Fournaise was classified as a continuing eruption (Alert 2-1).

Other
Guatemala’s Fuego was very active with up to 10 explosions per hour, plumes rising as high as 4.7 km above the vent, and incandescent ejecta causing rockfalls and audible booms. Santa Maria produced up to two explosions per hour, plumes to 800 m, and nighttime crater incandescence with rockfalls. In Costa Rica, Poas remained at Level 2 – Warning and is now Aviation Yellow, while Rincon de la Vieja and Turrialba stayed at Level 2 – Warning.
