Chile: Dark ash plume at Planchón-Peteroa

Planchón-Peteroa volcano

A webcam capture from Planchón-Peteroa in Chile, as seen at 4:29 PM (local time) on April 26, 2011.
Eruptions reader Gitta noted a fairly impressive ash plume at Chile's Planchón-Peteroa - at least seen on the webcam. The plume isn't especially tall (see below), at least not from the vantage point of the webcam, but it is rather dark and grey in complexion, suggesting a lot of fractured rock or new magma in the plume itself.

Planchón-Peteroa has been producing intermittent plumes for the past year or so, some as high as 4.6 km / 15,000 feet, but nothing in the way of a large eruption, which the volcano is definitely capable (see the VEI 4 eruption of 1762).

The activity has been fairly low as of late, with no SERNAGEOMIN update (spanish) on the volcano since last October. This current plume is likely just more of the same from Planchón-Peteroa, but at least today, the viewing is very nice to see the activity at the remote Chilean volcano.

Authorities in Ecuador closed schools and evacuated residents in areas near a volcano Tuesday after ashes spewing from its crater fell on homes and farms, state media reported.

Ashes from Tungurahua -- which means "throat of fire" in the native Quechua language -- rose more than 7 kilometers (4 miles) into the air Tuesday, the government news agency said.

Authorities issued an alert as monitors detected six eruptions, ranging from moderate to large, and a significant ash cloud Tuesday, state media said.

San Pedro, Laguna - The water temperature in the main crater of Taal volcano increased over the weekend, a sign that the volcano may be about to erupt.

Volcanologists raised alert level 2 over Taal early this month.

A bulletin released by the Philippine Institute of Volcanology and Seismology (Phivolcs) said the temperature of crater waters rose from 30.5 degrees Celsius to 31.5 degrees Celsius over the weekend.

The Shiveluch volcano has spewed a new plume of ash 7.5 km above the Russian Kamchatka Peninsula. The ash cloud sprawled 143 km to the northwest.

The authorities announced the orange alert level warning aircrafts about volcanic dust and gases in the air. At present, there is no risk to human health.

Shiveluch, is one of Kamchatka's largest volcanoes. It rises more than 3.200 meters above sea level.

Philippines: Intensity 3 quake 'with rumbling sounds' felt near Taal Volcano

Intensity 3 and Intensity 1 volcanic earthquakes were felt in two villages near Taal Volcano yesterday, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.

Phivolcs said in its April 20 bulletin that a total of 13 volcanic earthquakes were detected in Taal Volcano during the past 24 hours.

One of the quakes, which occured at 3:15 p.m. Tuesday, was felt at Intensity 3 in Barnagay Calauit and Intensity 1 in Barangay Pira-Piraso.

Phivolcs said that the tremor was accompanied by rumbling sounds.

In the Phivolcs Earthquake Intensity Scale, Intensity 3 is classified as "weak", but it is felt by many people indoors specially in upper floors of buildings.

Russia: Spewing volcano threatens Kamchatka reindeer

Kizimen
The continuing eruption of the Kizimen Volcano in Kamchatka poses a threat to wild reindeer which are listed as endangered species.

As the volcano continues to spew ash for hundreds of kilometers, reindeer are leaving their traditional habitat for lack of fodder.

Reindeer moss, the animals' only food in winter, is buried under a thick crust of ice and ash.

Experts from the Krontosky Nature Reserve warn that Kamchatka's less than 1,000 reindeer may die out as a result of the eruption.

Kizimen, one of the 29 acting volcanoes in Kamchatka, has been spewing ash since December 2010.

Early winter snow on Mt Ruepehu
Volcanic activity on Mt Ruapehu appears to be slowing according data monitored by GNS Science.

While activity seems to be decreasing overall, and there are no data to suggest an imminent eruption, the volcano remains in a state of elevated unrest above the typical background level.

The Aviation Colour Code remains at Yellow and the Volcanic Alert Level remains at Level 1.

The temperature of Crater Lake is down to around 33-34C from a peak of 41C in March 2011.

Water in the crater of Taal is reportedly heating up while the volcano's emissions of carbon dioxide have risen
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) maintained the Alert Level 2 hoisted over Taal Volcano, as 20 volcanic earthquakes were recorded during the past 24 hours.

Alert 2 status means present activities could eventually lead to an eruption, according to Phivolcs.

Phivolcs said there was a noticeable increase in seismic activity of the volcano. Water temperature at the Main Crater Lake also slightly increased from 29.8°C to 30.1°C.

Phivolcs advised the public to keep away from the Main Crater, Daang Kastila Trail and Mt. Tabaro because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

Indonesia's most active volcano Merapi has seen a new lava dome formation at a diameter of 400 meters recently.

"The dome is resulted from the latest eruption which has expanded to 400 meters in diameter," said Subandriyo, Chief of Volcanology Technology Research and Development Agency (BPPTK) of Yogyakarta, on Tuesday.

According to Subandriyo, the new lava dome is not visible, "because it does not overflow."

Taal Volcano quakes increase in number in 24 hours

According to the most recent bulletin of the Philippine Institute of Volcanology and Seismology (Phivolcs), there were 11 earthquakes produced by the activity of the Taal Volcano today, April 12, 2011. This is 4 quakes more than yesterday's recorded volcanic quakes.

The bulletin added that the carbon dioxide emissions of the Volcano is still in high levels which suggest anomalous gas release from the magma at depth. The Alert Level II hoisted last Saturday has not been lifted due to the increased activity of Taal Volcano.

The Institute had advised the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

In today's episode of TV Patrol, it was reported that there were cracks noted on the walls and floors of the houses and on the roads in Talisay, Batangas which is 10 km away from Taal Volcano. The Phivolcs is still to investigate what caused the cracks.
