Krakatau adds ash as Mayon lava flows persist amid busy Indonesia activity

Thu, 16 Jul 2026 22:26:31 +0000

Multiple Indonesian volcanoes were highly active today, while Mayon in the Philippines kept its lava moving down three gullies. Ash, gas, and steam emissions were also noted at Popocatepetl in Mexico, and steady activity continued at several Andes volcanoes. Compared with yesterday, ash emissions were explicitly reported at Krakatau.

Indonesia
Dukono, Ibu, and Semeru featured frequent explosions with plumes reaching up to 2.3 km at Dukono and 1 km at Semeru. At Krakatau (Level 3 - Standby), ash-and-gas plumes rose about 100 m. Lewotolok logged 157 explosions with low plumes, while Merapi (Level 3 - Standby) produced hot rockfalls traveling up to 1.8 km. Activity also persisted at Lewotobi and Karangetang.

Philippines
At Mayon (Alert Level 3), lava effusion persisted, with flows reaching 3.8 km (E), 3.2 km (SE), and 2.1 km (S), alongside Strombolian bursts and plumes up to 1.8 km. High SO2 emissions (8,050 t/d), frequent rockfalls, tremor, and PDC-related seismicity underscored the activity. Elsewhere, Taal produced plumes to 600 m, while Kanlaon puffed to 500 m and Bulusan showed low-level unrest with 150 m plumes.

Mexico
Popocatepetl released ash, gas, and steam under Yellow Alert - Phase 2.

South America
In the northern Andes, Reventador produced 67 explosions with ash-and-gas plumes to 1 km and incandescent rockfalls, while Sangay registered 11 explosions and thermal anomalies; in Peru, Sabancaya sent ash-and-gas plumes to 500 m.

Bagana Volcano (Papua New Guinea) – Activity Report 9–15 Jul 2026 (New Eruptive Activity)

Thu, 16 Jul 2026 21:59:07 +0000

The Darwin Volcanic Ash Advisory Centre (VAAC) reported that ash plumes from Bagana were visible in satellite images rising to 2.7 km (9,000 ft) a.s.l. and drifting S and SSE on 14 July. A strong thermal anomaly was also identified.

Etna Volcano (Italy) – Activity Report 9–15 Jul 2026 (New Eruptive Activity)

Thu, 16 Jul 2026 21:59:07 +0000

The Sezione di Catania - Osservatorio Etneo (INGV) reported eruptive activity at Etna’s summit craters during 6-12 July characterized by activity along the fissure between Voragine Crater (VOR) and Northeast Crater (NEC) and explosive activity at both NEC and Bocca Nuova Crater (BN). Strombolian activity and ash emissions at vents along the fissure began to decrease during the afternoon of 6 July and ceased during the early afternoon of 7 July. During the rest of the week gas emissions rose from the fissure and the pit crater on the upper E flank of VOR.
Explosive activity and gas emissions continued at NEC. INGV staff conducted a field survey on 11 July and observed modest intra-crater explosive activity at BN with ejected tephra falling back into the crater. Minor and episodic ash emissions rose from the crater and rapidly dissipated.
The Alert Level remained at Yellow (the second lowest level on a four-level scale) according to the Dipartimento della Protezione Civile.
