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,…

New activity/unrest was reported for 2 volcanoes from October 2 – 8, 2024. During the same period, ongoing activity was reported for 20 volcanoes.

Seismic activity at Mount Spurr volcano in Alaska remains elevated, with over 900 earthquakes detected so far in 2024, according to the Alaska Volcano Observatory (AVO). Despite the persistent unrest, no major shifts in earthquake frequency or intensity have been observed since the increase in seismic activity was first noted in April.

A small eruption occurred at Nagar Gri mud volcano on Myanmar’s Ramree Island at approximately on October 5, 2024, sending mud approximately 3 m (10 feet) into the air.

Moderate strombolian activity at Stromboli’s North Crater area on October 8, 2024, led to lava overflow, which gradually diminished by the morning of October 9 before intensifying again.

The INGV-Etneo Observatory reported a sequence of volcanic events on Stromboli within an hour on Sunday, October 6, 2024, starting with a high-energy explosion from the North crater at 00:17 UTC. This eruption triggered a lava flow along the Sciara del Fuoco, with ongoing spattering activity observed as of Sunday morning.

Six earthquakes were detected at Mount Adams in September 2024, the highest monthly total since monitoring began in 1982.
