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.
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.
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.
New activity/unrest was reported for 6 volcanoes from October 16 – 22, 2024. During the same period, ongoing activity was reported for 27 volcanoes.
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 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.
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.
New activity/unrest was reported for 3 volcanoes from October 9 – 15, 2024. During the same period, ongoing activity was reported for 17 volcanoes.
A gradual increase in volcanic unrest was observed at Spurr volcano in Alaska over the past couple of months, prompting the Alaska Volcano Observatory (AVO) to increase the Volcano Alert Level to Advisory and the Aviation Color Code to Yellow on October 16, 2024. Spurr is located about 120 km (75 miles) west of Anchorage.
A volcanic tremor lasting 10 hours and 30 minutes was observed at Taal volcano on Saturday, indicating sustained magmatic or hydrothermal activity beneath the surface. Such prolonged tremors are often associated with the movement of magma, volcanic gases, or fluids, which can cause increased pressure within the volcano’s system. This could lead to further unrest,…
