Storms and Floods

Malaysia – The situation in flood-hit Pahang has worsened, with more than 20,000 people evacuated to relief centres and a man and his son feared to have drowned. The two, were moving their belongings to a boat at about 8.30pm in Sungai Isap when they fell into the floodwaters.

Large swathes of the UK are braced for a storm bringing with it gale-force winds, possible travel disruption and the risk of some coastal flooding. Worst hit will be Scotland, where 80mph winds are expected, and the north and east of England. The combination of high tides, gale-force winds, large waves and a tidal surge would bring a risk of significant coastal flooding. In some places sea levels could be as high as those during the devastating floods of 1953 – although flood defences built since then meant many parts of the country were now better protected.

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): The New SE crater remains restless. As the following time-lapse video of the past 24 hours shows, there is occasional weak lava extrusion from effusive vents on the upper flanks, and rarely glow from the summit vent suggesting that the magma column is relatively still high inside the vent and sometimes produces deep-seated strombolian explosions.

Ambrym (Vanuatu): NASA astronaut Mike Hopkins captured a great space image of the active Marum and Benbow vents of Ambrym volcano on 2 Dec. Both vents contain active lava lakes.

Santa María / Santiaguito (Guatemala): Explosive and effusive activity have continued with little variation. Explosions sent ash plumes up to 700 m above the crater, and block lava effusion continues mainly at the eastern side of the Caliente dome where weak to moderate constant avalanches occur.

Pacaya (Guatemala): No changes in activity have occurred. Mild strombolian explosions continue from the Mackenney crater. Tremor and explosion signals are visible on the seismic recording.

Fuego (Guatemala): The observatory reports no significant changes. About 30-35 small to moderate explosions occurred during 3-4 Dec, often with strong shock waves that rattled windows and roofs in up to 6 km distance. Ash plumes rose to about 4.2 km altitude (500 m height) and produced light ash falls in W and SW directions (Morelia, Panimache and other villages). At night, incandescent avalanches from the crater are visible.
