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.

Storms and Floods

Death toll from Hurricane Sandy in the Caribbean rises to 58. Gale force winds are expected to arrive along portions of the US mid-Atlantic coast by late Sunday and reach Long Island and southern New England by Monday morning. Winds to near hurricane force could reach the mid-Atlantic states by late Monday.

Disease

The outbreak of dengue fever on the Portuguese island of Madeira has tripled and now cases are being seen in other European countries linked to travel to the island.

Storms and Floods

Hurricane Sandy kills 29 people on its path through the Caribbean and now targets the US east coast. A tropical storm watch for both the South Carolina and North Carolina coasts has been issued. A hazardous weather outlook warning has been issued for Connecticut. Central Florida is also on alert.

The floods in Chad continue to take a severe humanitarian toll. The number of flood-affected people in Chad has risen to 700,000, up from 445,000 in September while aid agencies estimate the loss or damage of 255,720 hectares of cropland, 94,211 houses and 1,015 schools. Some 70,000 people have been displaced by the flooding.

Levels of radioactive contamination in fish caught off the east coast of Japan near the earthquake and tsunami hit Fukushima nuclear plant remain raised. It is a sign that the Dai-ichi power plant continues to be a source of pollution more than a year after the nuclear accident. About 40% of fish caught close to Fukushima itself are regarded as unfit for humans under Japanese regulations.

Disease

E. coli outbreak in Belfast, Ireland grows to 124 confirmed cases with a further 166 probable cases.

52 cases of Ebola haemorrhagic fever (EHF) have now been reported in the Democratic Republic of Congo (DRC) to date. Of these, 25 have been fatal.

France and Spain join Italy and Switzerland in halting sales of Novartis flu vaccine.

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.

Heavy rainfalls around Tungurahua volcano in Ecuador triggered lahars one of which damaged the Baños-Penipe road.
