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
New activity/unrest was reported for 3 volcanoes from October 9 – 15, 2024. During the same period, ongoing activity was reported for 17 volcanoes.
Spurr volcano alert raised after increased seismicity and ground deformation, Alaska
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.
Taal volcano records 10-hour tremor as magmatic activity continues, Philippines
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,…
The Weekly Volcanic Activity Report: October 2 – 8, 2024
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 unrest continues at Spurr volcano in Alaska with over 900 earthquakes detected in 2024
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.
Nagar Gri mud volcano erupts in Myanmar’s Ramree Island
