Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

Tropical cyclone 04s (Kate), located approximately 280 nm west-southwest of Cocos Island, Australia, and is tracking southwestward at 04 knots.

Tropical depression 23w (twentythree), forms in the Western Pacific, is located approximately 575 nm southeast of Manila, Philippines, and is tracking westward at 05 knots.


Malaysia – At least five people have been killed in the floods along Malaysia’s east coast, with over 160,000 displaced. Malaysia has announced an extra $142m (£92m) to help victims of the country’s worst flooding in decades.


Roundup of Global Volcanic Activity

Bardarbunga (Central Iceland): The eruption continues, but seems to be becoming slowly weaker. The latest measurement shows the Nornahraun lava field measures now more than 81 square km. Seismic activity under the caldera has been slowly decreasing overall as well. However, the decreasing trend is very weak and the eruption could still continue for many months, or take a new, unexpected evolution at any time. The future, or probably 2015 will tell!

Fogo (Cape Verde): According to local press, volcanologist João Fonseca, responsible for volcanic monitoring and equipment maintenance at Fogo volcano, mentioned that volcanic activity shows signs of decreasing and that the eruption could be approaching its end. Still, the northern lobe of the recently active lava flow to the west remained active during the past days and smaller lobes advanced through more farm land in the Cova Tina area.

Shiveluch (Kamchatka): Explosive eruptions, by explosions and or partial collapse events of the active lava dome continue to occur regularly. On 26 Dec at 04:37 UTC, an eruption was reported to produce an ash plume that rose to 26,000 ft (8 km) altitude and drifted west. (Tokyo VAAC)

Aso (Kyushu): The eruption from the volcano’s Nakadake crater continues with relatively intense and near continuous strombolian activity. Incandescent material is frequently ejected several tens of meters above the crater rim. An ash plume rises a few hundred meters above the crater to up to 1-2 km altitude. A second vent inside the crater produces a dense steam plume and likely has some milder explosive activity as well.

Nishino-shima (Volcano Islands, Japan): The eruption continues well into its second year, steadily enlarging the island with lava flows. During the past weeks, most activity has been concentrated to produce flows towards the north and northwest where the island has been growing considerably. By now, nothing is left of the former small island, result of the 1973 eruption, and the surface of the island is currently about 10 times of what it had been before the ongoing eruption.

Santiaguito (Guatemala): Explosive activity at the Caliente dome has picked up. Explosions with ash plumes rising several hundred meters have become more frequent. The lava flow on the eastern side remains active, according the the observatory’s latest report.

Pacaya (Guatemala): INSIVUMEH reported a week ago that activity decreased and that there are currently no signs of explosive activity from the Mackenney crater. Only a steam and gas plume is being emitted.
