In the South Indian Ocean: Tropical cyclone (tc) 11s (Eleven), located approximately 700 nm east-northeast of Mauritius, is tracking west-northwestward at 10 knots.


Jakarta, Indonesia – Several areas in Jakarta have faced flooding after heavy rain on Tuesday evening caused the Ciliwung River to burst its banks in some areas. Seven districts and eight subdistricts in South Jakarta and East Jakarta have been affected by floods, with the water level between 10 to 100 centimetres high, the Jakarta Natural Disaster Mitigation Agency (BPBD) stated on Wednesday.


Wildfires – USA

Emergency crews on Tuesday struggled to contain deadly wildfires that have scorched hundreds of square miles of land in four states and forced thousands of people to flee their homes ahead of the wind-whipped flames. The fires have killed at least seven people.

The fires were burning in parts of Kansas, Oklahoma, Texas and Colorado, and warnings that fire conditions were ripe were issued for Iowa, Missouri and Nebraska, as powerful thunderstorms moved through the nation’s midsection overnight, spawning dozens of tornadoes, according to the National Weather Service.

In Kansas, wildfires have burned about 625 square miles of land, said Katie Horner, the spokeswoman for the state’s Department of Emergency Management. She said the largest evacuations were in Reno County, where 10,000 to 12,000 people voluntarily left their homes Monday night. She said 66 people from the area were in shelters Tuesday in Hutchinson, which is 40 miles northwest of Wichita, as crews continued fighting fires that started over the weekend.

In Colorado, a fire in rural Logan County burned more than 45 square miles, forced the evacuation of three schools and threatened as many as 900 homes. The Logan County Emergency Management Office said at least four structures, including three homes, were destroyed.

Meanwhile, authorities issued mandatory evacuations and closed part of Interstate 75 as a wildfire burned more than 6,000 acres in Florida’s Collier County.


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

Chirinkotan | Kuril Islands (Russia) : Based on satellite images, SVERT reported that on 1 March an ash plume from Chirinkotan rose to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted 165 km E. The Aviation Colour Code remained at Yellow (on a four-colour scale).

Etna | Sicily (Italy) : INGV reported that Strombolian activity at Etna’s New Southeast Crater (NSEC) cone had gradually intensified beginning at 1700 on 27 February. Lava overflowed the vent, quickly traveled down the S flank, and then slowed after reaching the gently sloping terrain. The flow spread SSW, towards the old cone of Monte Frumento Supino. During 27-28 February frequent Strombolian explosions ejected incandescent lava fragments up to 200 m above the vent. During a field survey on 28 February INGV-Osservatorio Etneo staff observed sporadic emissions of vapor and brownish ash from several vents within the NSEC. A new pyroclastic cone around the vent had grown higher than the highest points on the SEC (Southeast Crater) or NSEC. The lava flow slowly advanced on top of the snow, and by 1 March was about 1.5 km from the vent. By the late evening, activity declined, and the volcanic tremor amplitude rapidly diminished.

Klyuchevskoy | Central Kamchatka (Russia) :KVERT reported that a thermal anomaly over Klyuchevskoy was identified in satellite data during 25 February and 1-2 March. At 1340 on 2 March a gas, steam, and ash plume recorded by the webcam rose to altitudes of 8-9 km (26,000-30,000 ft) a.s.l. and drifted 110 km NE and NW. The Aviation Colour Code was raised to Orange (the second highest level on a four-colour scale).

Pacaya | Guatemala : INSIVUMEH reported that during 2-3 and 6-7 March weak Strombolian explosions at Pacaya’s Mackenney cone ejected material 5-10 m above the crater rim. Crater incandescence was visible at night and at dawn during 4-5 March.

Piton de la Fournaise | Reunion Island (France) : OVPF reported that the 28-day eruption at Piton de la Fournaise, beginning on 31 January and ending on 27 February, produced less than 10 million cubic meters of lava.
