Global Volcano Activity:

The lava lake at Kilauea volcano on Hawai’i within Halema‘uma‘u crater remains at high levels, although the inflation-deflation cycle has now entered deflation and the lake level has slightly dropped. Elevated earthquake activity continues to appear beneath the upper eastern rift zone.

In Mexico, Popocatépetl’s activity has increased again with about 2-3 explosions per hour. Some of these produce ash clouds rising up to 2 km height. An explosion during the night of 25-26 Oct ejected numerous incandescent bombs to the upper outer flanks of the volcano.

Fuego volcano in Guatemala has mainly had effusive activity the past days with the lava flow towards the Ash Canyon increasing in length again to now about 600 m.

During 25-26 Oct, Sakurajima volcano in Japan had 2 relatively strong explosions sending ash to more than 3 km altitude (10-11,000 ft).

Elevated surface temperatures were detected at Cleveland volcano in the Aleutian Islands, perhaps related to a new phase of lava dome growth. Seismic activity remains elevated at Iliamna and Little Sitkin volcano, but there have not been any other signs of activity recorded.

In Kamchatka: Shiveluch volcano’s lava dome continues to grow slowly and explosions could occur any time. According to video data, the volcano is steaming and there is incandescence above the dome. Seismicity is moderate, and satellite data show a thermal anomaly. A hot spot continues to be visible at Karymski volcano, seismicity is moderate and KVERT reports a possible small eruption with ash to 3,000 ft / 4 km altitude yesterday. Moderate seismicity, a visible weak steam plume and a thermal anomaly detectable on satellite data suggest that mild strombolian activity continues in the summit crater of Klyuchevskoi volcano. A thermal anomaly remains visible at Bezymianny although KVERT has not detected seismic activity recently. Activity at Kizimen has decreased over the past weeks, but incandescence, steaming and moderate seismicity continue to be registered, confirming that the lava dome remains active.

Alaid volcano in the Northern Kuriles continues to show a thermal hot spot and steaming could be observed from neighboring Paramushir Island.

The submarine eruption of Havre Seamount in the Kermandec archipelago discovered 9 Aug has been confirmed by direct observation. NZ scientists used multibeam sonar to map the seamount and found evidence of a new volcanic cone, 240 m tall and reaching withing 1,100 m below sea level, built on the side of the large submarine caldera of Havre volcano.

The tree disease which killed 90% of Danish ash trees has spread to the British countryside. Ash dieback has been found in the wider environment at sites in East Anglia, and there are fears it could wreak the same kind of damage as Dutch elm disease in the Seventies. The Chalara fraxinea fungus, which causes leaf loss and crown dieback and can lead to tree death, wiped out 90 per cent of ash trees in Denmark in seven years.

Global volcanic activity:

Popocatépetl’s activity in Mexico remains stable with about 2 weak explosions per hour. Most of these only produce steam plumes, only the stronger ones are accompanied by weak ash plumes. Crater glow is visible at night and a significant SO2 emission indicates that magma continues to rise in the volcano.

Explosive activity from Fuego volcano, Guatemala is increasing in favor of effusive. Since yesterday, there have been 13 weak to moderate explosions with ash rising up to 1000 m. The lava flow towards the Ash Canyon is still active and now 400 m long.

A mild ash explosion from the Santiaguito lava dome [Guatemala] occurred this morning with a weak plume rising to 3100 m altitude. Activity otherwise remains mainly effusive. The thick block lava flows that descend from the summit are still weakly active and produce avalanches of rocks detaching from their fronts.
