quote:

In Mexico is een eruptie van vulkaan Popocatépetl eergisteren vastgelegd door een webcam. Op deze fel versnelde beelden zie je hoe de vulkaan een enorme wolk van as en stof uitbraakt.

Omwonenden vulkaan Merapi op de vlucht

De vulkaan Merapi op het Indonesische eiland Java spuwde maandag rook en as. Honderden inwoners van dorpen aan de voet van de vulkaan zijn op de vlucht geslagen.

De vulkaan spuwde de donkerrode as duizend meter de lucht in, maar een uitbarsting bleef uit en de geldende alarmfase werd niet verhoogd.

De bijna drieduizend meter hoge Merapi is de actiefste van de vijfhonderd vulkanen die Indonesië telt. Bij de laatste grote uitbarsting, in 2010, vielen 347 doden.

August 17, 2013 – ALASKA – Seismic unrest is being reported at another Alaskan volcano. Tanaga is a 5,924-foot (1,806 m) stratovolcano located in the remote Aleutian Range of the U.S. state of Alaska. There have been three known eruptions since 1763. The most recent was in 1914 and produced lava flows. According to the Earthquake Report, a swarm of seven earthquakes have struck near the volcano in the last 24 hours- the strongest of which was a 4.7 magnitude. This may suggest magma intrusion under the volcano.

Number 69: Iceland - A small phreatic eruption seems to have taken place yesterday at the ice-covered Kverkfjoell central volcano. The steam-driven (no fresh magma involved) explosion followed a small glacial flood on 15 August the Kverkjökull glacier released into the Volga river and was probably a result of the pressure release during the flood. –Volcano Discovery

Kliuchevskoi (Kamchatka): A new eruption began at 06:30 UTC on 15 August, KVERT reports. Accompanied by strong tremor, strombolian activity has been taking place in the summit crater. Incandescence at the summit of the volcano’s summit were observed at night and a gas-steam plume containing small amounts of ash rose up to 18,000 ft (5.5 km) a.s.l. and drifted to the north-east of the volcano on August 16. Satellite data showed a big and bright thermal anomaly over the volcano on August 15-17. – Volcano Discovery

Indonesia Warns of Rising Volcanic Activity in East Province
JAKARTA, Indonesia—Indonesian authorities have been warning local villagers in East Nusa Tenggara Province about increasing volcanic activities in the area in recent days.

“The people around the areas should continue to practice caution” despite there not having been fresh volcanic activity on Wednesday, said Sutopo Purwo Nugroho, the spokesman of the National Disaster Mitigation Agency.

The agency reported on Tuesday two volcanoes in the East Nusa Tenggara Province have shown “increasing activities.” The volcanoes are subsea Mount Hobalt and and Mount Ili Werung.

It noted Mount Hobalt erupted Tuesday morning, spewing cloud as high as 6,560 feet above the sea level for around two minutes.

“Visually, the water near the volcano turned yellow and bubbly,” the agency said.

Meanwhile, Mount Ili Werung, located on the southern part of Lembata Island, started rumbling just before dusk Tuesday for about an hour and a half.

But the agency said, at least so far, it isn’t necessary for the villagers to evacuate their villages.

Six people were killed in the small Palue Island in the province when Mount Rokatenda erupted on Aug. 10, spewing hot ash and smoke up to 6,560 feet into the air. Nearly 3,000 people were evacuated from the area in the island since it first rumbled in October 2012.

East Nusa Tenggara is about 1,297 miles east of Indonesia’s capital city of Jakarta. Just west to the province is West Nusa Tenggara Province, famous for the Mount Tambora, whose eruption in April 1815 is cited as the largest volcanic eruption in the world in recorded history. The precise death toll from the eruption remains unclear, but it is believed to be at least 71,000. The eruption caused a “volcanic winter,” a reduction in temperature cause by volcanic ash and droplets of sulfuric acid. It made 1816 known as the year without summer due to the effects of the weather in North America and Europe.

Vulkaan in Peru blijft rook spuwen
De Ubinasvulkaan in het zuidwesten van Peru blijft rook en as spuwen. De vulkaan is al een hele week bijzonder actief en daar lijkt niet snel verandering in te komen. Integendeel, vulkanologen verwachten dat het tot een echte uitbarsting zal komen. "De rook en as die we nu zien zijn typische verschijnselen die een uitbarsting aankondigen", zegt Pablo Masias, een Peruviaanse vulkanoloog. De 150 inwoners van het dorpje Querapi, aan de voet van de vulkaan, zijn uit voorzorg geëvacueerd. De Ubinas wordt beschouwd als een van de actiefste vulkanen ter wereld. Sinds de 16e eeuw kwam het al meer dan 20 keer tot een uitbarsting. In 2006 spuwde de Ubinas een rookwolk 9 kilometer de lucht in.
