"By mid-August, Sakurajima Volcano—one of Japan’s most active—had erupted ash at least once every week during 2010. On August 19, 2010, an ash plume was sighted at 9,000 feet.."

Java, Bromo volcano erupts. 25 thousand people at risk
by Mathias Hariyadi
One of the mountains favoured by tourists in Indonesia is once again active. Local authorities prohibit access, because of the amount of ash, which is destroying crops and tourism industry. The people must cover their faces with a mask to guard against the heat. Jakarta (AsiaNews) - Mount Bromo in East Java province, a tourist destination of exceptional interest, is active once again. Its eruption threatens the livelihoods of about 25 thousand people. Located in the district of Probolingo, the mountain offers wonderful scenery. And nearby is another place of great beauty: a desert of sand home to a Hindu temple and a caldera volcano. Tourists are mainly attracted by the spectacle of sunrise over the mountain sides. Mount Bromo is a vital resource for the local economy. Residents of the area are largely employed in tourism: accommodation for hikers, guides, small restaurants, renting horses and jeep tours. But the rapid growth in eruptive activity is disrupting the lives of three districts, thousands of people are forced to wear masks, to protect their face from the heat. The latest reports say that the main roads leading to the mountains are covered in thick ash. Frequent rainfall in the month of December together with the ash has made the roads very slippery. Local authorities have banned access to tourists for security reasons. The eruption is destroying the local economy. Residents income comes primarily from the sale of vegetables to markets in the area. Farmers have already suffered damages in recent months from the eruption of Merapi. According to an estimate from state agency Antara at least 25 thousand people are seriously affected by the eruption, and are in danger of being put out of work and a livelihood.
Tungurahua, Ecuador Volcano, Sends 300 Fleeing From Truck-Sized Rocks
QUITO, Ecuador — Ecuador's Tungurahua volcano hurled truck-sized pyroclastic boulders more than a mile Friday in a powerful eruption that prompted at least 300 people to flee their homes, authorities said.
Schools were closed for a third straight day as ash showered down on a dozen towns in the sparsely populated area surrounding the 16,480-foot (5,023-meter) volcano.
Thundering explosions could be heard miles from Tungurahua, which is on the Andes cordillera 84 miles (135 kilometers) southeast of Ecuador's capital, Quito.
A state Geophysics Institute scientist monitoring the volcano from a nearby observation post said by phone that incandescent boulders were landing up to 1.2 miles (2 kilometers) beneath crater level.
"The smallest blocks are that size of an automobile while the biggest reach the size of a truck, which cause impact craters up to 10 meters (33 feet) wide as they hit the flanks," the scientist, Silvana Hidalgo, told The Associated Press.
She called the eruption level "moderate to high."
Civil defense officials reported an intense shower of ash east of the volcano, including in Banos, a tourist destination three miles (five kilometers) away that is popular for its hot springs.
The volcano has been active since 1999. At least four people were killed and thousands evacuated in eruptions in July and August of 2006.
Two Russian Volcanoes Spew Ash
Two of Far East Russia’s most active volcanoes threatened aviation and wildlife during eruptions that spewed ash above the Kamchatka Peninsula.
Ash from Shiveluch soared nearly five miles high near some key trans-Pacific aviation routes.
RIA Novosti reports an eruption of Kizimen volcano brought hazardous conditions to areas inhabited by wild animals, including some endangered species.
The news agency said reindeer were leaving their normal habitat because their usual winter food supply of moss was buried beneath a thick crust of ash-covered snow.
Experts from the Krontosky Nature Reserve told reporters that reindeer numbers may be reduced to less than 1,000 as a result of the eruption.
Four at Once: Volcano Quartet Erupts on Kamchatka
Volcanic eruptions are hardly a rarity. It seems that a new one goes off every few weeks or so somewhere in the world. But a string of four volcanoes
That, though, is what has taken place in recent weeks on the Kamchatka Peninsula in Russia's far east. Four different cones and mountains, all within 180 kilometers (110 miles) of each other, have been active simultaneously since late November. Given that volcano experts don't believe that the four volcanoes are being fed from the same magma source, the parallel eruptions would seem to be the geological equivalent of winning the lottery.
And, as a photography team from the Moscow-based Airpano discovered, the phenomenon presented a fantastic opportunity to produce some awe-inspiring images and videos. Indeed, the quartet of lava and ash-spewing peaks are so close to one another -- they lie within 180 kilometers (110 miles) of each other -- that that the film crew recently visited all of them in a single day
That volcanoes erupt in Kamchatka is, of course, hardly news. The peninsula, which has a total land mass that is slightly larger than Germany, is one of the most active parts of the infamous "Ring of Fire," the zone of volcanic and seismic activity that encircles the Pacific Ocean. Three tectonic plates -- the North American Plate, the Okhotsk Plate and the Pacific Plate -- collide beneath Kamchatka, with the peninsula's coastal range boasting 30 active volcanoes.
All four of the volcanoes now erupting have shown significant activity in recent years. Most recently, Tobalchik began spewing lava on Nov. 27 of last year, creating the impressive lava flows visible in the 360 degree video taken by Airpano. Shiveluch, the northernmost of the four, prefers shooting columns of ash high into the air, which it has been doing on a regular basis during the last four years since a magma dome in its crater exploded. Besymjanny awoke with a bang in the 1950s following 1,000 years of dormancy and has been active since then, with huge clouds of ash rising on a regular basis. Finally, the southernmost of the quartet, Kisimen, has been erupting regularly since 2010, and there is concern that it could perform a repeat of the violent explosion which sheered off half of the mountain some 1,300 years ago.
