"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

As Turrialba Volcano erupts again, scientists warn of increased health risks, economic damage

Lindsay Fendt

5 hours ago

At 4:55 a.m. Sunday, ash spilled from the crater of Costa Rica’s Turrialba Volcano for nearly an hour. Though the ash barely left the crater, located about 67 kilometer northeast of the capital San José, the wind carried it into the Central Valley — for the umpteenth time in recent months.

The eruption comes less than a week after the volcano shot a tower of ash 2.5 kilometers into the air, shutting down Juan Santamaría International Airport for the third time since March.

Since Turrialba Volcano re-awoke last October, volcanic ash has dirtied homes, damaged crops and mucked up travel plans. With its frequent eruptions, the volcano has gone from an interesting diversion to a nuisance for nearby residents and visitors.

And experts say the worst is yet to come.

Future eruptions, they say, could jeopardize the health of humans and the environment. They could also cause serious economic damage.

“There is a very high possibility that [the volcano] will reach a higher level of activity,” said Lidier Esquivel, the chief investigator of risk management for the National Emergency Commission (CNE).

Scientists with both the Volcanological and Seismological Observatory of Costa Rica (OVSICORI) and the National Seismological Network (RSN) expect Turrialba’s eruptions to gradually increase over the next few months until the volcano is erupting on a near weekly basis. Scientists have also confirmed that lava has reached the surface.

“The volcano is already throwing lava, it is fragmented lava that is creating the ash,” Guillermo Alvarado, coordinator for volcanic and seismic threats and monitoring for the Costa Rican Electricity Institute, said during a volcano roundtable event last week.

Alvarado said these lava fragments actually create a natural form of glass, which when inhaled can pose serious health risks to both animals and humans. Children, the elderly and people with pre-existing respiratory problems are especially at risk when breathing in ash.

“At this point there have been very few serious health problems to arise, but ash can cause respiratory problems, throat problems and burning in the eyes or skin.” Esquivel said. “As more people are regularly exposed to volcanic ash, we expect to see these problems in a larger portion of the population.”

TIMELINE: A history of major volcanic eruptions in Costa Rica

The ash can also kill plants, contaminate water supplies and damage electronic equipment.

The ash has already done its fair share of damage. Within 5 kilometers of the volcano, ash and acid rain have killed off crops, damaged homes and contaminated rivers. Three schools in the area have been forced to close each time the volcano erupts. And there have been reports of some residents developing respiratory problems.

If conditions continue to worsen, the area may have to be evacuated. 

While the immediate vicinity of the volcano is the most vulnerable to ash damage, emergency officials are growing increasingly concerned about the rest of the country.

“With the right wind, depending on the weather, some of these volcanic episodes will bring ash over San José and the surrounding metropolitan area,” Esquivel said. “This will happen more often if the eruptions increase.”

San José’s greater metropolitan area houses more than half of Costa Rica’s population and virtually all of the country’s industry. According to Esquivel, the city’s high concentration of electronic equipment is at great risk for damage as the presence of ash becomes more frequent.

The National Emergency Commission is preparing for the worst case scenario, where Turrialba’s explosions become much stronger, similar to those of the Irazú volcano in the 1960s, which regularly showered San José with ash. 

“We can’t predict with 100 percent certainty what will happen on any given day,” Esquivel said. “All we can do is be prepared.”

In Costa Rica, Turrialba volcano spits ash and smoke

The Turrialba volcano has spewed a fresh column of smoke and ash that reached Costa Rica's capital, San Jose, 60 kilometers away, authorities say. Its previous rumble had come just last Thursday.

The moderate eruption, which included rocks around the crater area, hit at about 2100 UTC on Monday, raising eyebrows but not great alarm about 40 miles away, in Costa Rica's capital, San Jose, the Volcanic and Seismic Center reported.

Accompanied by a strong smell of sulfur and a coating of ash falling from as high as 2.5 kilometers (1.5 miles) in San Jose, the eruption of the the 3,340-meter (10,950-foot) volcano lasted about a half hour.

Inactive for 130 years, Turrialba rumbled back to life in the 1990s. In late October last year, the volcano erupted with great force, spewing ash and magma.

It has rumbled ever since. An eruption in early March (pictured) shut down Juan Santamaría, the main international airport, for nearly two days. Monday's eruption did not look like it would lead to flight cancellations.

UPDATE: Costa Rica's Turrialba Volcano erupts, forcing capital airport to temporarily close

UPDATE, 8 p.m. on Monday: 

The ash from Turrialba Volcano has forced operators of the Juan Santamaría International Airport, outside Costa Rica’s capital city of San José, to temporarily close, affecting at least seven inbound flights. According to Silvia Chaves, a spokeswoman for Aeris, the company that operates the international airport, seven inbound flights are either delayed or cancelled until further notice. That number could change in coming hours, she said. No outbound flights have yet been affected.

Did she blow? NW submarine volcano likely just erupted

http://www.seattletimes.com/seattle-news/science/did-she-blow-nw-su...

A new seafloor observatory operated by the University of Washington is providing unprecedented detail about the possible eruption of a submarine volcano off the Northwest coast.

Beginning Thursday, April 23 — the day after the workshop ended — the new sensors recorded 8,000 small earthquakes in a 24-hour period. The volcano’s caldera, which had been swelling rapidly from an influx of magma, collapsed like a deflated balloon.

“All the alarm bells were going off,” said Oregon State University volcanologist Bill Chadwick, who along with a colleague predicted last year that the volcano would erupt in 2015. “It was very exciting.”

https://translate.google.com.ar/translate?sl=es&tl=en&js=y&...

reported by the National Service of Geology and Mining of Chile

Chile: The National Geology and Mining (Sernageomin), run by the National Network of Chile Volcanic Surveillance, reported today that the third Calbuco volcano began eruptive pulse so the red alert is maintained at 20 kilometers around the massif. They are working to evacuate nearby villages.

For now, they consider that the ash could reach the area of ​​El Bolson, to extend toward the Atlantic coast in Peninsula Valdes as published by news portal Patagonian weather.

At 13:10, Sernageomin reported that the volcano had started his third eruptive pulse stage that had been predicted.

VAAC Buenos Aires estimated the height of the plume at 16,000 ft (5 km) altitude.

Ash Fallout from Chile's Calbuco Volcano Threatens Local Water Supply (Apr 27)

A state of emergency has remained in effect for miles around Chile’s Calbuco volcano, as officials pledged to help thousands of residents faced with thick ash, the threat of contaminated drinking water and the possibility of lava flow tied to last week’s eruptions.

Chilean television showed some residents wearing masks as they tried to clean volcanic ash from the roofs of their houses and from the streets. Many of the 6,000 people who were evacuated from towns surrounding the volcano in southern Chile had not been allowed to return to their homes as of midday Monday.

Authorities also warned of possible contamination of drinking water supplies and farm crops due to the toxic content of the volcanic ash. The volcano had been inactive since the early 1970s before erupting Wednesday and Thursday.

Officials said a state of emergency remained for a 13-mile radius surrounding the 6,200-foot Calbuco volcano, about 650 miles south of the capital, Santiago, in the Los Lagos region. Rain could trigger mudslides and overflow rivers.

Chile’s National Geologic and Mining Service estimated that the volcano had so far emitted 210 millon cubic meters of ash, which covered areas in the immediate Chilean area of Los Lagos but also fell on the Argentine side of the border.

Lava from Sumatra's Sinabung Volcano Destroys Village (Apr 28)

Mt. Sinabung erupted again on Tuesday night with a series of strong pyroclastic flows, forcing hundreds of residents to flee from Gurukinayan subdistrict, Payung district, Karo regency, North Sumatra.

The largest lava flow reached 5 km away and destroyed the evacuated village of Guru Kinayan on the southern slope of the volcano.

The flows, at least 9 in total, resulted from the partial collapse of the recently emplaced lava lobe on the steep upper flank.

More on the Calbuco eruption in southern Chile.

Volcano Calbuco in southern Chile erupted with little warning for the first time in more than four decades on April 22, sending a thick plume of ash and smoke 30,000 feet into the sky.

As night fell, about 4,000 people had so far moved out of the area, an evacuation radius of 20 kilometers had been established and classes were canceled in surrounding towns, authorities said.

Winds blowing northeast were pushing the column of ash and smoke toward Argentina.

"In this situation, with the eruption column so high, the main risk is that it collapses, falls due to gravity because of its own weight and causes a pyroclastic flow," Gabriel Orozco, a vulcanologist with Chile's geological and mining service, said on local TV.

A pyroclastic flow is a superheated current of gas and rock that can destroy nearly everything in its path and travel at speeds upwards of 200 to 300 kilometres per hour.

Canadian-born Trevor Moffat, who lives in Ensenada, some 10 kilometres from the volcano, said the eruption happened without warning. Volcano Calbuco's last known eruption was in 1972 and the most recent major eruption happened in 1961.

"It sounded like a big tractor trailer passing by the road, rattling and shaking, guttural rumbling ... we left everything there, grabbed my kid, my dog, got in the car with my wife," said Moffat, who was driving to nearby Puerto Varas at the time.

"All the neighbours were outside, a lot of young people crying. Armageddon-type reaction."
