India – A massive landslide in Manikaran Sahib Gurdwara in Himachal Pradesh, India has claimed the lives of at least 8 people and injured 10 others.

Uruguay – Following a period of drought, Uruguay has been hit by two weeks of heavy rains causing floods that have forced a record 5,132 people, mostly children and elderly, to leave their homes and take refuge in government-assisted shelters where they are provided with food and accommodation, according to Uruguay’s news agency El Pais. While to date no casualties have been reported, the number of evacuees is expected to rise. Two weeks of heavy rains have caused the country’s rivers Olimar, Yi and Uruguay to rise above the level defined by authorities as safe and have provoked floods in different provinces. The floods come after a period of drought that forced Uruguayan authorities to limit the use of drinking water late July.

Hungary – A downpour in Budapest triggered flash floods in the Hungarian capital, disrupting electricity and snarling public transport.


Wildfires – USA – Overview

Wildfires continue to rage along the United States’ West Coast, endangering people and property and stretching thin the resources available to fight them.

The National Interagency Fire Center (NIFC) reports about 30,000 wildland firefighters and support personnel are fighting wildfires in 10 states. And it appears to be only getting worse – on Tuesday, 16 new large fires were reported, mostly in Idaho and Montana.

The total number of large active fires stands at 88, with 21 in Idaho, 17 in Washington, 16 in California, 14 in Montana and 11 in Oregon.

The NIFC has requested 200 active duty military personnel to help battle the wildfires.

The year-to-date acres burned is now about 7.1 million acres. This is the earliest the number of national acres burned has been more than 7 million in the past 20 years. About 72 percent of the current year-to-date acres burned are from the large fires in Alaska earlier this summer. The NIFC reports active fires are spread over 1,186,753 acres.


Roundup of Global Volcanic Activity

Karymsky (Kamchatka): The volcano had an explosion this morning that produced an ash plume that rose to 15,000 ft and drifted SE.

Sakurajima (Kyushu, Japan): Activity has actually decreased and been relatively low at the volcano during the past days. However, the risk of a major eruption remains according to the Japan Meteorological Agency who maintains alert level 4 (preparation for evacuation).

Karangetang (Siau Island, Sangihe Islands, Indonesia): Thermal signals from the volcano have been increasing over the past days, suggesting that the lava output at the summit crater has increased. This could again again to dangerous pyroclastic flows if the lava dome or lava flows become unstable on the steep upper flanks of the volcano. Such flows can easily reach inhabited areas. During the past months (at least since May) the volcano has been constantly active with a weakly alimented lava flow on the upper southern flank, which has been generating frequent incandescent rock falls. It decreased during July, but a new phase of more violent activity might be in the making now and could make new evacuations necessary. Alert level of the volcano remains at 3 (out of 4).

Raung (East Java): It seems that at least some activity has resumed again. Several observers reported a light ash plume rising from the volcano and drifting SW.

Dukono (Halmahera): Ash emissions from the volcano continue to be intense. This morning, an ash plume extended 50 km ENE.

Colima (Western Mexico): Explosive activity continues with sometimes relatively strong eruptions every few hours.

Popocatépetl (Central Mexico): Activity at the volcano, relatively low at the moment, has remained more or less unchanged. Lava is slowly being extruded in the inner summit crater and occasionally produces small explosions and less vigorous degassing events (“exhalations”). CENAPRED reported yesterday: “In the last 24 hours the seismic records of the survillance system of Popocatepetl volcano registered 9 very-low-intensity exhalations. Through mounted cameras on the volcano, the cloudy conditions not allow to observe the volcano continuously, and it was noticed that some of these were along with emissions of steam and gas.

Santiaguito (Guatemala): Activity at the Caliente lava dome remains essentially unchanged. Some explosions produced ash plumes of up to 500 m height and the eastern blocky lava flow remains weakly active.

Pacaya (Guatemala): Weak strombolian activity continues inside the Mackenney crater and produces small plumes of gas and light ash. Glow is visible at night.

Fuego (Guatemala): Activity has decreased during the past days. INSIVUMEH reported only few and relatively weak explosions occurred during yesterday.

Turrialba (Costa Rica): After 3 months of relative quiet, a small eruption occurred at the volcano on Saturday (15 Aug). At 01:47, an explosion of gas and ash generated a plume that rose 500 m. The activiy was preceded by more than five hours of sustained volcanic tremor and increased seismic activity since early on 14 Aug.

Cotopaxi (Ecuador): During the night and this morning, some relatively small explosions occurred at the volcano, producing plumes of up to 700 m height.

Tupungatito (Central Chile and Argentina): A volcanic-tectonic earthquake of magnitude 3.2 Richter occurred under the volcano yesterday. The epicenter was at 8.2 km depth 25 kilometers northwest of the main crater. This might announce a period of unrest at the volcano. SERNAGEOMIN keeps alert level at “green”, but with “special attention”, according to a newspaper article. Tupungatito, the northernmost historically active volcano of the central Chilean Andes, is located on the Chile/Argentina border 99 km east of Santiago capital. It is one of the country’s more active volcanoes. Since 1829, frequent small explosive eruptions have been recorded, last in 1986.
