Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

In the South Indian Ocean: Tropical Cyclone “Carlos” (04S) continued moving west south-west over the south-west Indian Ocean, slightly weakening, but remaining a Tropical Storm. Its centre is located approximately 300 km south south-west of the south-western coast of La Reunion (France). Over the next 24 hours, it is forecast to continue moving south-west, strengthening. Local media reported at least 4 000 people left without power, several flights cancelled and schools closed throughout La Reunion.

Singapore – Flash floods were reported in various parts of Singapore including the Orchard Road area as heavy rains hit the island on Wednesday (Feb 8) evening.

DR Congo – Two people died on Tuesday in the Democratic Republic of Congo’s capital Kinshasa after torrential rains caused flooding in some parts of the city. The city’s wet season normally runs from October to May, and it is mostly of the impoverished districts of the capital that are hardest hit by flooding as they sit near the Ndjili and Matete tributaries of the giant Congo River.

Anthrax in Zambia – Update

In a follow-up on the anthrax outbreak in Western Province, Zambia, local media report six additional fatalities in the past five days. According to Sikongo Health Director Fredrick Siyunda, the six victims contracted anthrax after eating tainted meat from cattle. This brings the human death toll due to anthrax in Western Province to eight since the outbreak began.

Roundup of Global Volcanic Activity – New Activity for the week of 1 February-7 February 2017

Chirinkotan | Kuril Islands (Russia) : On 6 February SVERT noted that the Aviation Colour Code for Chirinkotan had been lowered to Green (lowest level on a four-colour scale).

Cleveland | Chuginadak Island (USA) : On 3 February AVO reported that recent satellite data indicated that a new lava dome had been extruded, and partially filled Cleveland’s summit crater. The new dome is about 70 m in diameter, similar in size to previous lava domes that have developed on the crater floor. Since explosive activity has sometimes followed lava-dome extrusion, AVO increased the Aviation Color Code to Orange and the Volcano Alert Level to Watch. Weakly elevated surface temperatures were identified in several satellite images during 6-7 February, consistent with the presence of a lava dome that began forming in late January.

Takawangha | Andreanof Islands (USA) : On 3 February AVO stated that the seismic swarm that began at Takawangha on 23 January continued but at a decreased rate and intensity. The rate of earthquakes peaked at 190 events on 24 January, and since then had steadily declined; 2-8 events per day were recorded from late January to 3 February. Most of the events were located 7-8 km ESE, at shallow depths. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory.

Piton de la Fournaise | Reunion Island (France) : OVPF reported that seismicity and inflation at Piton de la Fournaise significantly increased on 2 January. Based on seismic data, an eruption began at 1940 on 31 January. Visual observations on 1 February confirmed that the active vent was located about 1 km SE of Château Fort and about 2.5 km ENE of Piton de Bert. Lava fountains rose 20-50 m above the 10-m-high vent, and ‘a’a lava flows branched and traveled 750 m. Two other cracks had opened at the beginning of the eruption but were no longer active. Tremor levels decreased in the early hours of the eruption; RSAM values then fluctuated at mid-range, and lava-fountain heights were variable (between 20-50 m). On 2 February two lava fountains at the vent were visible, and lava flows had traveled an additional 500 m E. The vent was 128 m long and about 35 m high at the highest part. The next day RSAM levels were more stable, at a value which was half of what it was at the beginning of the eruption. On 4 February OVPF noted that significant fluctuations of volcanic tremor were detected for more than 24 hours, with intensity levels reaching those observed at the onset of the eruption. Higher levels of seismicity continued through 7 February. Poor weather conditions prevented visual observations during 4-7 February.
