Kamchatka
The Shiveluch Volcano erupting in Kamchatka has spewed ash nine kilometers high, the Kamchatkan territorial emergency situations department reported on Tuesday. No ashfall has been reported from towns nearby.

"The volcanic event occurred on Tuesday afternoon. The ash cloud stretched northwest, bypassing populated areas," the report said.

No ashfall has been reported from towns nearby, it added.

Nevertheless, rescuers advised tour operators to avoid paths around the volcano, for which a red alert has been issued.

Shiveluch is the northernmost active volcano of Kamchatka situated 45 kilometers away from the town of Klyuchi in the Ust-Kamchatsky district with a population of approximately 5,000.

It is also one of the largest Kamchatkan volcanoes. Shiveluch became active in May 2009 and got a fissure that is almost 30 meters deep in its dome.

Klyuchevskoy
With a pillar of fire stretching up into the clouds, this spectacular image captures the moment a volcano erupted in remote Russia. The stream of lava rose up to a kilometer above the summit of Klyuchevskoy, one of the active volcanoes on the Kamchatka peninsula in the east of the country. The volcano, which erupts around every two years, is one of the largest on-land active volcanoes, according to the U.S. Geological Survey. It stands at 15,584f t on the north end of a belt of 30 active volcanoes.

Comment: From the recent chain reaction on the 'Ring of fire':
Kliuchevskoi on the Kamchatka Peninsula: Kliuchevskoi on the Kamchatka Peninsula in Russia had a busy weekend after its busy week - and a lot of the action was caught on the webcams pointed at the volcano or by satellite. For much of Friday and into Saturday (October 18-19), the volcano continued to produce some vigorous lava fountains and lava flows, mixed in with Strombolian explosions that sent bombs down the slopes of the volcano. This activity was significant enough to cause some aviation alerts even over the western Aleutian Islands.

People in Naxxar, Madliena, Mellieha and in Gozo said this evening that they could (faintly) see the latest eruption of Mt Etna in Sicily.

The distance between Mount Etna and the tiny island state of Malta is about 312 km and this is indeed a very rare sight. During explosive Etna eruptions in the past Malta has suffered from ash plumes fallout on several occasions.

In 2002 Mount Etna made a heavy physical presence in Malta when ash from the volcano crossed the Mediterranean and coated the country in an insidious film of black fine dust after a volcanic plume was swept there by north to north easterly winds from Sicily.

The volcano at Mount Sinabung at Jakarta, Indonesia, erupted six times early Monday, shooting volcanic ash 2,000 meters into the sky. Thousands have been evacuated from the region since the Sinabung volcano began erupting sporadically in September. 5,000 people were evacuated from the area the day before the eruption on Monday, bringing the total number of evacuees to 11,000. There have been no casualties so far.

The Sinabung is just one of 35 active, erupting volcanoes in the world, according to a categorized list on Volcano Discovery. Of the 35 currently erupting volcanoes in the world, seven are in Indonesia. Most of Indonesia is situated along the "Ring of Fire" -- a horseshoe shaped ring around the Pacific where most earthquakes and volcanic eruptions take place.

Here's a map of the Ring of Fire and the 35 volcanoes that are experiencing sporadic eruptions and other active volcanic activity. Click here to see what sort of volcanic activity that volcano is experiencing.

Six new eruptions in the morning sent lava and searing gas tumbling up to 1.5 kilometres down the slopes of Mount Sinabung in North Sumatra province. Volcanic material spewed as high as 2,000 metres into the air a day after authorities had raised the volcano's alert status to the highest level.

About 15,000 people have been evacuated from 17 villages in the danger zone five kilometres around the crater, National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said. The evacuation zone was expanded from three kilometres.

Beautiful but deadly: Villagers sit on a truck as they evacuate to a safe spot, while Mount Sinabung spews ash into air at Aman Teran village in Karo regency, North Sumatra on Sunday. The volcano continued to emit volcanic ash, creating an 8,000-meter plume of ash, as thousands of residents remained in temporary shelters out of fear of more eruptions.
Karo administration spokesperson Jhonson Tarigan said Sunday that the number of villagers displaced continued to rise as Mount Sinabung erupted again on Saturday evening.

"There has been a 100 percent increase in the number of those displaced. The number is now at least 11,618 from 19 villages," he said Sunday.

Jhonson said to handle the evacuees, the Karo administration had prepared 26 shelters with supplies. Of the total, 22 are already full.

Volcanology and Geological Disaster Mitigation Center (PVMBG) head Hendrasto said Mt Sinabung's most recent eruption prompted the body to raise the volcano's status on Sunday to the highest level, "siaga" or "red alert".
"This is Sinabung's highest level of activity. The intensity of the eruptions continues to increase," said Hendrasto.
He said that at 2 p.m. local time on Sunday, Sinabung was continuing to spew a column of ash up to 8 kilometers high.

Black 'hail' rains down on Italian town after eruption


The Extinction Protocol
Mon, 25 Nov 2013 05:11 UTC

An Italian photographer has filmed a town being blanketed in stone and ash as it fell from the sky like hail stones after Mt Etna erupted again on Saturday. Footage shows the town covered in inches of black ash spewed out by the volcano and pushed hundreds of kilometers across the Strait of Messina from Sicily to the mainland. It rained down from dark cloud above and spread over the town's streets and cars.

Some residents used umbrellas to shield them from the chunks of ash that were almost 2cm in size.

Mt Etna has erupted several times this year, one as recently as Saturday 16 November, but its last major eruption was in 1992. There were no evacuations from yesterday's eruption, but a highway was closed for half-an-hour and four air corridors that service Sicily's Catania Airport, south of the volcano, were closed for some time.

Comment: Can you see the normalcy bias in action? People are just walking about as usual, using umbrellas to shield against the rocks/ash as though the danger is and will remain benign.

Why have 10 major volcanoes along the Ring of Fire suddenly roared to life?

The Pacific Ring of Fire.
Ten major volcanoes have erupted along the Ring of Fire during the past few months, and the mainstream media in the United States has been strangely silent about this. But this is a very big deal. We are seeing eruptions at some volcanoes that have been dormant for decades. Yes, it is certainly not unusual for two or three major volcanoes along the Ring of Fire to be active at the same time, but what we are witnessing right now is highly unusual. And if the U.S. media is not concerned about this yet, the truth is that they should be. Approximately 90 percent of all earthquakes and approximately 80 percent of all volcanic eruptions occur along the Ring of Fire, and it runs directly up the west coast of the United States. Perhaps if Mt. Rainier in Washington state suddenly exploded or a massive earthquake flattened Los Angeles the mainstream media would wake up. Most Americans have grown very complacent about these things, but right now we are witnessing volcanic activity almost everywhere else along the Ring of Fire. It is only a matter of time before it happens here too.

Sadly, most Americans cannot even tell you what the Ring of Fire is. The following is how Wikipedia defines the "Ring of Fire"...
The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes.
An easy way to think about the Ring of Fire is to imagine a giant red band stretching along the perimeter of the Pacific Ocean.

And yes, that includes the entire west coast of the United States and the entire southern coast of Alaska.
