"Of course all volcanoes will explode, as this is going to be a very severe pole shift. What about the months and years preceding the pole shift? It is no secret that Mammoth Lake and the caldera of Yellowstone are warming up, and the populace has been prepared for these occurrences by the movie Volcano where there, in the middle of LA, lava is bubbling up. In fact, there is a fault line running from the approximate San Diego/LA area, up into the Sierras, and this is liable to rupture rather violently during one of the quakes that precedes the pole shift by some months. Volcanic eruptions from that area in the Sierras can be expected. Will Mount St. Helen erupt? All volcanoes that have been active within the memory of man will begin spewing and burping and oozing, and many that were not expected to become active will reactive. "   ZetaTalk - Feb 15, 2000

Ecuador's Tungurahua Volcano Buries Locals With Ash (Nov 19)

Residents from communities near Ecuadors Tungurahua volcano faced a massive cleaning operation after the volcano erupted, covering houses and fields with smoke and ash.

Authorities issued an orange alert as emissions reached 2,500 metres above the crater.

In nearby Queros, one of the most affected communities, officials registered 10kg of ash per square metre.

As he swept the street near his house, resident Luis Vaca said the volcanic material was damaging crops. Ash is falling everywhere; its strong, especially in the countryside where its falling more heavily. Its damaging the crops. It would be good if the president came to visit us, he said.

Volcanologist Patricia Mothes confirmed that eruptions have been substantial. These accumulations of ash that have been falling are the greatest masses of ash that we've registered in the past five years, she said.

Most residents are staying off the streets to avoid breathing in the ash while schools in the provincial capital of Ambato, have been closed.

Indonesia's Mt Sinabung volcano erupts again

http://news.asiaone.com/news/asia/indonesias-mt-sinabung-volcano-er...

MEDAN - Mount Sinabung in Karo regency, North Sumatra, erupted forcefully once again on Wednesday and may threaten the opening of the Lake Toba Festival by Tourism Minister Arief Yahya in Berastagi, also in Karo, slated for Thursday.

No casualties were reported following the eruption, but pyroclastic flows drifting to the southeast affected a number of villages that have long been abandoned by residents.

"The current wind direction is directed to the southwest, but if it blows to the east the Lake Toba Festival will be disrupted as the spread of ash would reach Berastagi," Mt. Sinabung Observation Station staff member Deri Hidayat told The Jakarta Post.

Deri said the volcano discharged the clouds at 1:47 a.m. and 9:28 a.m.

He added the pyroclastic clouds, which drifted as far as 3.5 kilometers, affected Bekerah and Simacem villages.

He said both villages had long been left empty as they were inside a designated danger zone.

Deri added that Mt. Sinabung had also emitted volcanic ash to a height of 2,000 meters toward the southwest. He said the spread of ash could disrupt the Lake Toba Festival if the wind changed direction in coming days.

He said volcanic activity could increase within the week, adding that the volcano could discharge a bigger volume of pyroclastic flows and ash.

"The biggest eruption took place on Tuesday, when the volcano discharged pyroclastic clouds 13 times, compared to only twice today," said Deri.

According to him, the potential for pyroclastic flows remained great due to a lava dome buildup on the southeastern section of the peak.

Deri said the lava dome could collapse anytime and trigger huge pyroclastic flows.

Consequently, added Deri, his office had recommended that the regional administration evacuate human settlements within the danger zone.

Since an eruption in September 2013, volcanic activity at Mt. Sinabung has never entirely ceased. Thousands of residents moved away at that time, only returning home last month after the volcano showed decreased activity.

The eruptions have killed at least 17 people and destroyed thousands of houses and hectares of farmland.

Flights Out Of Bali Still Limited As Volcano Continues To Spew Ash (Nov 15)

People would normally be afraid for their lives if they are stuck in a place where an active volcano is continuously spewing ash and preventing them from going back home. Not in Bali.

Thousands of tourists were stranded on three Indonesian islands after ash from an erupting volcano forced the closure of airports and blanketed villages and farmlands.

Mount Rinjani on Lombok Island blasted ash and debris roughly 3,500 metres into the air on Wednesday, said Sutopo Purwo Nugroho, the National Disaster Mitigation Agency spokesman.

Airlines Virgin Australia and Jetstar have been taking people home with recovery flights. All flights had to be cancelled the whole weekend of Nov. 14 and 15 due to another bout of ash cloud emission. Virgin Australia has already stated that its priority is bringing Aussies home from Bali rather than risk more people going into the holiday destination.

"As Mt Rinjani continues to erupt and flying conditions remain unpredictable in the days to come, our priority is to bring guests home from Bali, rather than fly more guests in who could potentially be delayed in returning home due to ongoing eruptions," Virgin Australia said in a statement.

Likewise, Jetstar also made an announcement of the airlines' flight activities in their website. "All flights on Sunday, 15 November from Australia to Bali have been cancelled... The movement of the ash cloud is highly unpredictable and flights are subject to change based on assessment of safety to fly and local approvals from airport authorities," it announced.

Offshore mud volcano erupts in Sea of Azov (VIDEO)
Published time: 27 Oct, 2015

https://www.rt.com/news/319795-mud-volcano-azov-sea/

An abandoned autumn beach looking out on the Sea of Azov became a popular sightseeing attraction over the weekend, after mother nature created an incredible mud volcano, which formed a wide, flat island just a few dozen meters away from the shore.

Spewing a slurry made of water and gases mixed with sand and dirt, the mud volcano shot several meters into the air as it started forming an artificial island on Sunday, just off the coast of the Taman Peninsula.

The act of nature was recorded by local beach strollers who witnessed the mud volcano, most typically formed after hot water below the earth's surface begins to blend with mineral deposits, pushing the mixture to the surface. But unlike an actual volcano, the muddy imitation produces no lava.

Guatemala issues orange alert over erupting Fuego Volcano

http://tribune.com.pk/story/989179/guatemala-issues-orange-alert-ov...

GUATEMALA CITY: Emergency service officials in Guatemala on Tuesday issued an orange alert over increasing eruptions from the country’s southeastern Fuego volcano and ordered the evacuation of a nearby hotel.

The 12,346-foot high colossus, whose name means “fire” in Spanish , showed heightened activity overnight, sending columns of ash high into the sky, spilling lava down its side and provoking small tremors.
Fine ash was falling on at least six villages and on the town of San Pedro Yepocapa, in the indigenous province of Chimaltenango, a state spokesman for the Disaster Reduction National Coordination Committee, David de Leon, told reporters.

The country’s Seismology and Vulcanology Institute urged authorities to consider taking precautionary measures for air traffic.

Peru's Ubinas Volcano Erupts Again (Nov 5)

Ubinas volcano registered a new explosion today and sent ashes over local communities in the Moquegua region of southern Peru.

The Volcanological Observatory of the Institute of Geological Mining and Metallurgy (Ingemmet) reported that the eruption has sent ashes over Querapi, Ubinas, Escacha, Tonohaya, Sacohaya and San Miguel villages.

The explosion was recorded at 12:15 p.m. today and emitted a moderate plume of ashes and gases that reached about 2,000 meters above the crater of Ubinas volcano.

The ashes dispersed over a distance of 10 kilometers to the southeast toward the mentioned villages.

About 600 families live near Ubinas volcano within a radius of 12 kilometers. In situations such as these, authorities advise that locals protect themselves with masks and goggles and guard water supplies from contamination.

Flights to Bali Canceled by Volcanic Eruption (Nov 3)

Volcanic ash is again wreaking havoc on Bali holidaymakers, with hundreds of flights in and out of Denpasar cancelled.

By Wednesday, that had resulted in the cancellation of 692 flights, both domestic and international, leaving many travelers stuck on the island or unable to reach it.

Two other airports in the region -- one on Lombok and the other in Banyuwangi in East Java -- have also been closed for the same period as Denpasar, Barata said.

Days after the Indonesian island volcano Mount Rinjani erupted, the blast has deterred travel to and from the area for many people, pro golfers included. Jessica Korda, Beatriz Recari, Azahara Munoz and So Yeong Ryu were all stuck on Bali, a nearby island, as ash, smoke and debris left the surrounding area unsafe for air travel.

That meant Recari and Munoz were unable to make it to Japan for the first round of the Toto Japan Classic and were forced to withdraw.

The eruption has intensified considerably over the past few days. Activity takes place from a lateral vent on the Barujari cone inside the volcano's caldera, producing continuous ash emissions and feeding a new viscous lava flow. The lava flow has been advancing more than 500 m in two lobes towards the NE.

This current more intense phase of the eruption seems ot have started in the early afternoon of 2 Nov, when ash emissions became large enough to produce a plume that drifted westwards and reached Bali, where the airport of Denpasar was shut down. The plume was almost 400 km long this morning and the shut-down of the airport has been causing significant flight disruptions. When it can be reopened will depend on whether ash emissions continue and the prevailing wind direction in the coming days.

On Lombok island itself, the rumblings from the eruptions are heard in many areas. Access to the summit area of Rinjani has been closed and a 3 km exclusion zone around the caldera rim is in place. Several villages on Lombok reported ash falls.

An Unexpected Eruption From Chile’s Lascar Volcano

LASCAR, IN THE northern Andes of Chile, erupted unexpectedly today, producing a small plume of light grey ash that reached 2.5 kilometers (~8,200 f... above the volcano (see above). The fact that there seemed to be little in the way of precursory activity (earthquakes, increased gas emissions) from Lascar suggests that this blast may have been a phreatic explosion driven by water flashing to steam in the volcano’s summit crater or conduit.

Due to this minor eruption, the SERNAGEOMIN has raised the alert status at Lascar to Yellow, although the volcano is in a fairly remote part of the Chilean Andes—the Global Volcanism Program reports only ~8,100 people living within 100 kilometers (62 miles) of Lascar.

It has been over 2 years since Lascar last did anything and its last major eruption of Lascar was in 2005. However, it has produced some spectacular eruptions in the recent past, including the 1993 eruption that was a VEI 4. As with any of these small blasts, volcanologists will watch Lascar to see if this is a sign that it is awakening or merely a blip. Based on images on the Lascar webcam, the eruption appears to have waned rapidly (see below).

The SERNAGEOMIN maintains two webcams pointed at Lascar, although only one is running right now.

Costa Rican Volcano Spews Ash; Latest in a Continuing Series of Eruptions

Costa Rica's Turrialba volcano released a column of gas and ash into the sky on Tuesday in the latest of a series of eruptions at the site in central Costa Rica.

The eruption, which occurred at about 8:30 Tuesday morning, is a continuation of a series of eruptions which have been generated since the end of the week, geologist Floribet Vega told the International Business Times.

“Today's [eruption] was a little bit stronger, not extremely bigger that it sent ash to the central valley, but it's a little bigger than what we have seen,” she said.  

Costa Rica’s National Emergency Commission told QCostaRica.com that the volcano was especially active over the preceding weekend, with at least 26 eruptions accompanied by seismicity.

The Turrialba Volcano National Park, about an hour’s drive from the capital in San Jose, has been shut since 2009 due to the increased activity at the site, the IBT reports.

Although significant emissions of ash have been reported at the volcano in recent years, magma has rarely been observed at Turrialba's crater.

"When there is a magmatic eruption, we're not going to find that a high proportion of material has been moved around,” said volcanologist Geoffroy Avard. “We're going to find a majority of material which is fresh and young and very little material which has been moving around. So the proportion is going to be the opposite of what we have today.”

Volcanic Activity Summary (Oct 26)

Explosion at Aso volcano early on 23 Oct 2015

Eruption at Turrialba yesterday morning (OVSICORI-UNA webcam)

Cotopaxi volcano today

Eruption at Tungurahua volcano yesterday

Aso (Kyushu): While the volcano continues to degas strongly and has intermittent, mostly small ash emissions, a stronger explosion occurred again early on 23 Oct around 6 am local time. An ash plume rose approx. 1.5 km above the Nakadake crater and dissipated quickly. Alert level remains at 3 out of 5, and an exclusion zone of 2 km around the crater is in place.

Bagana (Bougainville Island, Papua New Guinea): Ash emissions occurred from the volcano yesterday, suggesting ongoing mild explosive activity. VAAC Darwin reported a low-level plume extending 50 km northwest from Bagana.

Batu Tara (Sunda Islands, Indonesia): A volcanic ash plume at 5,000 ft (1.5 km) altitude extending 80 km west of the volcano was reported by VAAC Darwin this morning.

Soputan (North Sulawesi, Indonesia): The volcano is calm at the surface, but seismic activity shows it is at unrest and might erupt again soon. Deep volcanic quakes (5-10 km depth) and shallow tremors has been more frequent (10 -15 times per day) since 3 oct - 22 October. This suggests there is probably magma raising up slowly, but there are still no glowing spots visible.

Dukono (Halmahera): The volcano continues to erupt continuous, loud, roaring jets of gas and small amounts of spatter from vents at the bottom of the deep crater.
Ash plumes are regularly being reported by VAAC Darwin.

Turrialba (Costa Rica): After several months of relative calm, the volcano began to erupt ash plumes again since 23 Oct. Some of the explosions have been relatively strong and caused very small pyroclastic flows limited to the crater area. The origin of these emissions are likely phreatic explosions, i.e. caused by overheated ground water flashing to steam. Whether this is the case or at least some fresh magma is involved is unclear. Seismic activity, which could suggest the rise of new magma, has been reported to have picked up recently.

Cotopaxi (Ecuador): No significant changes have occurred during the past days. The activity remains characterized by intense degassing and occasional mild ash emissions mixed into the plume.

Tungurahua (Ecuador): Mild to moderate ash emissions, with ash plumes rising 1-2 km above the crater, have become more frequent over the past days, suggesting the volcano's activity has started to picking up. An explosion at 04:33 yesterday morning was seen ejecting incandescent material that rolled down the western flank to up to 1 km distance.
Light ash fall occurred later in Chacauco, Cotaló and Manzano. The ash was reported to be black and red in color and sugary in grain size. The first (color) suggest that it is from new magma (as opposed to typically gray-brown colored ash from pulverized older rock). The volcano observatory also reported an increase in seismic activity associated with fluid movements. One possibility is that the volcano (after all, one of the world's most active ones) enters a more vigorous phase of activity in the near future, as often occurred in the past.
