Increased eruptive activity at Santiaguito volcano prompts safety alerts in Guatemala
The Santiaguito volcanic dome complex in southwestern Guatemala is experiencing increased eruptive activity, with frequent explosions and lava block detachment from the Caliente Dome. The eruptions produce ash plumes reaching 3.5 km (11 500 feet) a.s.l. and dispersing it up to 30 km (19 miles) southwest and south.
Mount Marapi blankets parts of West Sumatra in ash, Indonesia
Mount Marapi experienced four explosions on October 27, 2024, producing thick ash columns up to 4 km (13 000 feet) a.s.l. that drifted westward over populated areas, blanketing them in ash.
Popocatepetl volcano releases high-level ash emissions over Gulf of Mexico
Popocatépetl volcano in Mexico has shown increased activity over the past few days, with significant ash and SO2 emissions recorded since October 24. On October 26, volcanic ash cloud was estimated at approximately 9.1 km (30 000 feet) above sea level, extending about 833 km (517 miles) northeast of the summit into the Gulf of Mexico.
Significant volume of gas plume and volcanic material detected at Nyamulagira, DR Congo
The Toulouse VAAC is reporting the detection of a significant volume of gas and volcanic material over Nyamulagira Volcano in the eastern Democratic Republic of the Congo, starting at approximately 11:15 UTC on October 25, 2024. Volcanic ash cloud was observed rising to 4 km (13 000 feet) above sea level at 13:00 UTC. As a result the Aviation Color Code was raised to Red.
The Weekly Volcanic Activity Report: October 16 – 22, 2024
New activity/unrest was reported for 6 volcanoes from October 16 – 22, 2024. During the same period, ongoing activity was reported for 27 volcanoes.
Magma accumulation under Svartsengi signals new volcanic eruption, Iceland
The Svartsengi volcanic system in southwest Iceland is showing increased volcanic activity due to magma accumulation beneath the surface. Magma is moving into shallow chambers, causing ground uplift and seismic activity. In recent days, seismic activity has slightly increased, with around five minor daily earthquakes along the dike, the most prominent being M1.5, indicating growing pressure.
New sensors deployed to monitor Mount Adams following spike in earthquake activity, U.S.
New temporary sensors were deployed by the USGS and PNSN around Mount Adams this month in response to the volcano experiencing an unusual spike in seismic activity since September 2024.
Kanlaon volcano emits over 3 244 tonnes of sulfur dioxide amid ongoing increased unrest, Philippines
A series of brief ash plumes from Kanlaon volcano painted the sky gray on Saturday, October 19, 2024, with the clouds rising 500 m (1 640 feet) before drifting southwest and leaving traces of ash in the surrounding area.
The Weekly Volcanic Activity Report: October 9 – 15, 2024
