Now it's Japan's Sakurajima volcano: Strong explosions and near constant ash emissions

After a short phase of weaker activity, the volcano began to erupt more violently yesterday with a series of powerful explosions that sent ash plumes up to 15,000 ft (4,5 km). Near-constant ash emissions have been taking place from the Showa crater.

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.

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


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?

Ring of Fire
© Wikimedia CommonsThe 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.

A new island has appeared in the Pacific. A submarine eruption just off Nishino-Shima Island Japan has erupted for the first time in 40 years. The Japanese Navy noticed the explosions as boiling lava met sea water giving rise to plumes of steam and ash.

Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. A steam and ash cloud rose two miles into the sky and the grumbling of the mountain could be heard in towns a few miles away.

In Guatemala the 'Fire Mountain' belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. The explosions and shock waves occurring in the volcano can be felt by residents over 6 miles away. Doors and windows are reported to be rattling, but there has been no damage so far.

In Vanuatu the Yasur volcano is giving some cause for concern. Although the explosions are quite weak the continuous ash that is coming from the mountain is starting to build up on farming land.

Milan - Mount Etna, Europe's most active volcano, has erupted again, showering volcanic ash on towns dotting the mountain's slopes and nearby Taormina.

The eruption Saturday did not force any evacuations, but a highway was closed for half an hour as a precaution. Authorities also briefly closed two of four air corridors serving the nearby Catania airport but air traffic was not interrupted.

Etna erupts occasionally. Its last major eruption occurred in 1992.

A tiny new islet has been created in Japan after a dramatic volcanic eruption in the Pacific Ocean. The news was confirmed by officials on Thursday. It has happened for the first time that the nation has come across such a phenomenon. Smoke was spotted by the Navy to have engulfed 1,000 kilometers (600 miles) south of Tokyo on Wednesday. Birth of the islet was verified later on by Japan's coastguard around the Ogasawara island chain.

Plumes of smoke ash billowing from the 200-metre island can be witnessed through a video. "Smoke is still rising from the volcanic island, and we issued a navigation warning to say that this island has emerged with ash falling in the area", said a spokesman for the maritime agency.

Increasing activity being reported at volcanoes in Guatemala and Vanuatu

Image
Guatemala - Two lava flows are active on the upper slopes of the volcano at the moment, to the Taniluya (south) and Ceniza canyon (SE). The effusive activity started on 11 Nov and increased on 18 November, reaching a length of 600 m. Constant avalanches detach from the flow fronts. At the same time, explosive activity at the summit crater remained at low to moderate levels, with strombolian explosions that produce ash plumes of up to 800 m height and incandescent jets visible from distance. Some of the explosions generate shock waves that can be felt and heard in up to 15 km distance, causing roofs, doors and windows of houses to rattle. Fine ash fall occurred in Panimaché, Morelia abd Sangre de Cristo. -Volcano Discovery

Weak explosions at Yasur
: Geohazards reports that the volcano continues to produce near-continuous ash emissions while explosions are relatively weak at the Yasur volcano on Vanuatu. This phase of ash emissions began on 3 November and are likely to continue into the coming days and weeks. Yasur Alert Level is still maintained at Level 1. Villages and communities located close and far away from the volcano, especially those in the prevailing trade winds direction (NW) are likely to receive ash falls. - Volcano Discovery

Mexico's Colima volcano showing two strong exhalations; ejecting lava down its slopes and ash skyward

Image
On Monday night and Tuesday morning, the Colima volcano showed two strong exhalations; ejecting lava down its slopes and ash skyward, that has reached several villages. Since last Sunday, the Volcan de Fuego de Colima was reactivated after several weeks of apparent calm and until Tuesday registered between 30 and 35 puffs per day, spewing lava down its slopes and ash that reached the people of Cheese, municipality of Cuauhtémoc, Colima, and some towns in the state of Jalisco.

Yesterday at 21:45 hours this morning between 8:00 and 8:30 am, the volcano emitted two strong exhalations heard that reached in the communities closest to the "granite colossus," mainly in the municipalities of Comala and Cuauhtémoc. From the city of Colima there was a big cloud of steam that rose to just over 2 miles. The chief operating officer of the State System of Civil Protection, Melchor Ursua Quiroz, said: "The volcano has been recharged" and in the last two days has been sharp exhalations, which triggered an alert status from monitoring equipment installed before this new volcanic activity.
