Storms and Floods

Tropical Storms

In the Atlantic:

Tropical storm Jerry forms located about 1240 mi (1995 km) E of Bermuda. Not a threat to any land.

In the Western Pacific:

Typhoon Wutip was located approximately 175 nm northwest of Da Nang, Vietnam. The final advisory has been issued on this system.

Tropical depression Sepat is located about 84 nm north of Chichi Jima, Japan.

Tropical storm Fitow is located approximately 430 nm north-northwest of Koror, Palau.

Typhoon Wutip – 3 Chinese boats sink. At least 70 people have been reported missing. Five boats carrying more than 150 people encountered strong winds from Typhoon Wutip on Sunday in the South China Sea. A rescue operation is under way and reports say 14 people have been found.

The storm was expected to make landfall in central Vietnam on Monday and thousands have been evacuated there. The boats ran into strong winds near the Paracel islands, around 330km (200 miles) from China’s southern coast. Two of the boats, from southern Guangdong province, sank on Sunday, and contact was eventually lost with a third boat. At least 10 ships and six planes are involved in rescue operations. Officials have advised local fishing boats to berth to avoid rough waters.

On Monday, Vietnam was anticipating widespread flooding and landslides – Typhoon Wutip is said to be the most powerful to hit the country this season. The country’s weather forecaster is expecting the typhoon to bring heavy rain and sustained winds of up to 93mph (150km/ph). More than 40,000 villagers from areas that were expected to be affected by the typhoon have been moved to safety.

NewsBytes:

Rock slide in Colorado on Monday – 5 buried and killed. Some of the rocks involved in the slide were “half the size of a car”. Boulders exceeding 100 tons crashed into a viewing area a half-mile up a popular day hike area. The slide left a football-field-sized gash below Mount Princeton.

An EF-1 tornado touched down near Puyallup, Washington, USA, causing damage to buildings and tipping a train off its tracks.

Weeks of heavy rains that began in mid-August have left much of Mauritania’s capital city, Nouakchott, and six of the surrounding regions under water, creating “unprecedented” damage according to the Department of Civil Protection.

Disease

Wild poliovirus in the Horn of Africa – update

Three suspected cases of wild poliovirus type 1 (WPV1) from South Sudan are currently being investigated. All three patients are girls, two of whom are approximately two-years-old and one is eight-years-old. All had previously been immunized with oral polio vaccine (OPV).

Volcanos

Roundup of Global Volcanic Activity:

Monte Albano (Italy): A second (and much more violent) geyser-like fumarole or mudvolcano recently appeared off shore near Fumiciono, approx. 100 meters out from the beach in the area where the new port of Rome is being built. It is an underwater vent that produces fountains of upwelling sediment-rich water driven by strong degassing from the sea floor.

Gorely (Southern Kamchatka): KVERT has no seismic data due to technical problems. The volcano continues to produce strong degassing, but has not erupted.

Klyuchevskoy (Kamchatka): Activity remains strong. A small explosion this morning produced an ash plume rising about 700 m above the summit and drifting 50 km to the east. The lava flow remains active and can be seen on webcam images at night.

Kizimen (Kamchatka): Activity (extrusion of lava at the summit) continues, but has decreased recently, as incandescent rockfalls have become more rare. Seismic activity remains “moderate” (KVERT) and strong degassing can be seen. About a week ago, the prominent spine at the summit dome collapsed.

Karymsky (Kamchatka): KVERT reported an explosion that produced an ash plume rising to 5-6,000 ft (1.5-1.7 km) altitude and drifted 30 km ESE. Seismic activity is moderate and a thermal hot spot at the summit is visible on satellite data.

Shiveluch (Kamchatka): Activity continues at moderate levels with little changes. The viscous lava dome remains active and produces occasional small ash explosions and avalanches.

Tolbachik (Kamchatka): No seismic or surface eruptive activity has been recorded recently. The eruption can probably by now be regarded to be over, but KVERT maintains Aviation Color Code yellow.

Bezymianny (Central Kamchatka Depression): The strong seismic activity of nearby Klyuchevskoy volcano obscured the seismicity of Bezymianny, which likely remains active with slow extrusion of its lava dome. Video data showed a moderate gas-steam activity of the volcano (KVERT).

Rabaul (Tavurvur) (New Britain, Papua New Guinea): Activity continues. The latest NOAA satellite image data shows increased SO2 emissions.

Ulawun (New Britain, Papua New Guinea): A relatively strong eruptive phase seems to be occurring at the volcano. An ash plume rose to 12,000 ft (3.6 km) altitude last evening and a significant SO2 plume is visible on satellite data.

Batu Tara (Sunda Islands, Indonesia): Relatively frequent larger strombolian to vulcanian explosions continue to produce ash plumes regularly spotted on satellite data. The ash plumes reach altitudes of about 7,000 ft (2.1 km).

Dukono (Halmahera): Ash emissions have been seen on satellite data during the past days, confirming significant ongoing explosive activity.

Copahue (Chile/Argentina): New ash emissions started last night. The increase of activity also manifested itself in visible incandescence since the night of 26-27 Sep. The volcano had been quiet since the last time similar ash emissions and some incandescence were spotted in mid August. Sernageomin has not (yet) commented on this new activity.
