Description
Science is quick to point out that strange happenings, even remotely, can impact the entire planet, and the eruption of the Pavlof volcano in a remote part of Alaska is quickly pointing out how cause and effect can impact everyone on the planet according to and article published on Christian Science published May 19, 2013. The Pavlof volcano began erupting Monday spewing ash clouds as high as 15,000 feet. By Wednesday the ash clouds had reached heights as far as 20,000 feet. It was at this point the National Weather Service designated this as a “significant meteorological event that could disrupt local air traffic.” If the ash clouds from Pavlof’s eruptions reaches 35,000 feet it will then begin to “disrupt international flights that use Alaskan airspace as a corridor for traffic between” North America and Asia. That is not in the forecast at the moment however, experts believe the eruptions can continue on for a month, at least a few weeks. If it does impact air traffic it can disrupt thousands of different areas in our lives from store shelves being light to loved ones not making it home on time. The video above is about another volcano that erupted midway through 2011 in South America which interrupted airway traffic and caused volcanic ash to be blown halfway around the world.

Description
Pavlof Volcano continues to erupt on the Alaska Peninsula, about 625 miles southwest of Anchorage. The Alaska Volcano Observatory reports a plume of steam, gas and ash reached up to 22,000 feet Sunday and was visible on satellite images drifting southeast over the north Pacific. Trace amounts of ash were reported in Sand Point, a city of nearly 1,000 on Popof Island about 55 miles east of the volcano. The volcano observatory says seismic activity remains elevated at the 8,262-foot volcano that began its latest eruption May 13. The volcano last erupted in 2007 for 29 days.

The  Watchers

 

 

According to AVO (Alaska Volcano Observatory) Pavlof volcano continues to erupt. Lava fountaining at the summit has been observed and photographed, and a continuous ash, steam, and gas cloud generated by the activity extends downwind from the volcano for 50 to 100 km at an altitude of about 6 km (20,000 ft) above sea level.

 

 

This natural-color satellite image, collected by the Advanced Land Imager (ALI) on the Earth Observing-1 (EO-1) satellite, shows Pavlof on May 16, 2013. A brown ash plume blew from the summit towards the southeast, and gray ash from earlier explosions covered the snow on the volcano’s upper slopes. To the northeast, additional ash rose from an ongoing lava flow.

On the morning of Thursday, May 16, 2013 the cloud was carried to the southeast, AVO reports. Satellite images show persistent elevated surface temperatures at the summit and on the northwest flank, commensurate with the summit lava fountaining and resulting lava flow.

 

AVO raised Volcano Alert Level from Advisory to Watch and Aviation Color Code from Yellow to OrangeSeismic activity remains elevated with nearly continuous tremor recorded on the seismic network, the agency reported.

Description
Mexico’s Popocatepetl volcano has blown steam for days, prompting authorities to prepare for possible evacuations, but residents are used to their towering neighbor’s rumblings and keep fearlessly heading to work. Popocatepetl, which means “smoking mountain” in the Nahuatl language of the Aztecs, spewed more steam, gas and ash that rose three kilometers (two miles) above the crater early Tuesday, according to the National Disaster Prevention Center. National civil protection coordinator Luis Enrique Puentes said the volcano was “totally calm” following the eruption, which belched out glowing rocks. While there was no immediate need to evacuate the population, the volcano could erupt again Wednesday, he added. The volcano, which is 55 kilometers (34 miles) southeast of Mexico City, has also rumbled and spewed molten rocks in recent days. Last week, it covered several towns in ash, including the capital of Puebla state.

Authorities have raised the alert level to “Yellow Phase Three,” the fifth of a seven-stage warning system, restricting access to an area of 12 kilometers (7.5 miles) around the volcano and preparing evacuation routes. But people living in the nearby town of Santiago Xalitzintla appear calm despite the activity inside the 5,452-meter (17,887-foot) high volcano, known locally as “Gregorio” or “Don Goyo” and considered a magical rainmaker by indigenous populations. “We go out, we look at it and we go back to sleep very soundly,” said Guadalupe de Santiago, balancing a basket of candy on her head near a church in this town just 12 kilometers (7.5 miles) south of the volcano.

“(The volcano) takes care of us. Look at all the water he’s sending us,” she said as rain fell on her. Hundreds of soldiers were sent to Santiago Xalitzintla and two other towns in case the volcano erupts and forces the evacuation of 11,000 residents in this area surrounded by corn fields and small cattle farms. The soldiers checked the condition of roads in case they need to be used for an evacuation and the two shelters were set up in the state of Puebla to house 5,000 people. Around 4.5 million people live within 50 kilometers (31 miles) of Popocatepetl, which had its last major eruption in 2000, forcing thousands of people to evacuate from surrounding towns.

Description
Thousands of people living in the shadow of this looming Mexican volcano have been placed on high alert following a dramatic increase in seismic activity from the Popocatepetl crater. The 17,886 ft active volcano near Mexico City, known as Popo, rumbled and shook during the night on Saturday, and has been spewing ash, lava and steam in recent days. Officials have closed off an exclusion zone around the cone of the volcano and are poised to evacuate towns in its foothills as experts warned of plumes of steam reaching more than half a mile into the sky above the crater. Authorities have alerted town in two central states as well as the capital, after Mexico’s National Disaster Prevention Center elevated its alert level to Yellow Phase 3 – the fifth rung on a seven-stage warning scale. Should the alert level rise thousands of people could be evacuated from the most vulnerable villages in the shadow of the peak. Shelters have been set up in case authorities are forced to evacuate residents. A seven-square-mile exclusion zone has been imposed around the cone of the volcano, and soldiers and federal police have been deployed to the area amid fears of further, more violent eruptions from Popo. Popocatepetl is an Aztec word meaning ‘Smoking Mountain’. Popo lay dormant for decades until it began putting out small eruptions of ash almost daily in 1994. These eruptions started strengthening two weeks ago and have increased even more this weekend.

Description
Seismic activity is continuing at the Popocatepetl volcano near Mexico City and authorities say they have readied shelters and identified evacuation routes in case they should be needed. Mexico’s National Disaster Prevention Center says there were two explosions at the white-capped volcano between Tuesday night and Wednesday morning. The center says the volcano spewed a plume of steam about a mile (1.5 kilometer) into the sky. Authorities continue to monitor the volcano’s activity but have not ordered any evacuations. Rain has been forecast for the area, however, and authorities say towns nearby could be flooded with ash mud. Popocatepetl has put out small eruptions of ash almost daily since a round of activity began in 1994. The eruptions started strengthening two weeks ago and increased even more this weekend.

Increased volcanic activity at Popocatepetl volcano

 

 

Popocatepetl volcano in Mexico has plumed steam for days, alerting authorities to prepare for possible evacuations. According to CENAPRED (Centro Nacional de Prevención de Desastres) at 6:46 UTC on May 15, 2013 there was an explosion that produced incandescent fragments throwing them around the volcano reaching distances up to 1.5 kilometers from the crater, while also generating a plume of ash more than 3 kilometers high which winds scattered northeast. An episode of spasmodic tremor followed, accompanied by incandescent fragments thrown at distances up to 500m on the northeast slope, and ash emission which winds carry northeast.

During an aerial survey flight by CENAPRED on the morning of May 14, 2013 it was seen that the lava dome has enlarged significantly and is now 350 m in diameter and 50 m thick. But after an explosive event on May 14, 2013 at 2:56 pm UTC it could be observed that the dome had somewhat deflated, although it did not decrease significantly. This situation is possibly the beginning of the dome´s destruction.

 

Last week, it emitted ash covering several towns, including the capital of Puebla state.

Description
Tremors were detected at Pavlof Volcano, 625 miles southwest of Anchorage, according to the Alaska Volcano Observatory. Satellite imagery showed the mountain was “very, very hot,” said John Power, the U.S. Geological Survey scientist in charge at the observatory. The aviation alert level for Pavlof was raised from “yellow” to “orange.” A major ash emission could threaten international flights. Pavlof is 37 miles from the community of Cold Bay, which was notified of the new activity that began about 8 a.m. Monday. Because of clouds, the volcano was not visible to the village of 100. The volcano last erupted in 2007, but residents there said that eruption had no impact on Cold Bay, likely because the winds blew any ash fall away. Ash clouds were visible to residents, however.

Description
An Alaska volcano exhibiting “elevated seismic activity” has spewed ash clouds skyward – as high as 20,000 feet above sea level – an observatory reported Wednesday. As was the case a day earlier, the Pavlof Volcano was on “watch” status on Wednesday because of heightened activity, and it was also under an orange code that relates to how its rumblings might affect planes flying over its summit. Both these alert levels are the second most serious out of four options, according to the Alaska Volcano Observatory. Pavlof is the higher of the two volcanoes, reaching to 8,261 feet, and the one that is connected to the Alaskan mainland. The Alaska Volcano Observatory’s Wednesday update noted persisting “elevated seismic activity” as well as reports of steam and ash clouds. Web camera images show the plume “rising occasionally up to about 20,000 feet above sea level,” the same height at which a pilot on Wednesday reported a “dark ash cloud” stretching east-northeast. The volcano observatory also reported a “diffuse ash plume” on Tuesday night at an altitude of 15,000 feet and visible downwind for up to 100 miles.

Scientists at the Alaska Volcano Observatory were able to get clear views of two restless volcanoes today. The images show that both Cleveland Volcano in the Aleutian Islands and Pavlof Volcano on the Alaska Peninsula are oozing lava.

Cleveland started erupting earlier this month, with six separate explosions sending up multiple ash clouds. The volcano has been quiet since early last week, but the new satellite imagery shows a lava flow coming out of the southeastern side of the crater. The flow is about 100 yards wide, and a mile long.

Mexican authorities raised the alert level for the Popocatepetl volcano near Mexico City on Sunday morning after observing an increased level of explosive activity. The lava dome of Popocatepetl, some 50 miles to the southeast of the capital, may expand and unleash increasingly powerful explosions of ash and lava, Mexico’s National Center for Disaster Prevention said in a statement. The alert level for the towering volcano was raised to yellow phase three from yellow phase two, on orders from the country’s Interior Ministry. It is the third-highest warning on the center’s seven-step scale. This change in activity in the 5,450-meter (17,900-foot) volcano could provoke big explosions capable of sending incandescent fragments out over considerable distances, the center added.

Last Modified: Sunday, May. 12, 2013 – 8:15 pm

 

Seismic activity has increased at the Popocatepetl volcano near Mexico City, leading authorities to alert towns in two central states and the capital.

Mexico’s National Disaster Prevention Center says the white-capped volcano spewed a plume of steam more than a half mile (1 kilometer) into the sky. The volcano shook during Saturday night, sometimes emitting glowing rock over the crater.

The government deployed soldiers and federal police to the area Sunday in the event of a bigger eruption, and officials closed off a seven-square-mile (18-square-kilometer) zone around the cone of the 17,886-foot (5,450-meter) volcano. State authorities prepared shelters.

Popocatepetl has put out small eruptions of ash almost daily since a round of activity began in 1994. The eruptions started strengthening two weeks ago and have increased even more this weekend.

Description
Mexico’s Popocatepetl volcano has spewed ash over several towns in the central state of Puebla, just 55 kilometers (35 miles) southeast of Mexico City, but the country’s capital was spared. The volcano blew a huge stack of smoke that went 3,200 meters (10,500 feet) skyward late Tuesday, but surrounding residents were not in danger, said Jesus Morales, Puebla’s civil protection director. A three-centimeter (one-inch) thick carpet of ash covered nearby towns, forcing people to wear masks. The National Disaster Prevention Center said Wednesday that ash also fell in the state capital of Puebla. The 5,452-meter (17,900-foot) high Popocatepetl is Mexico’s second highest peak after the Citlaltepetl volcano.

 

 

 

 

Mexico’s famous Popocatepetl volcano experienced one of its largest explosions in years, causing its eruption to cover about 30 communities with ash, according to reports.

    A plume of steam and ash is seen rising from the Popocatepetl volcano in San Nicolas de los Ranchos. The volcano has experienced one of its largest explosions in years, causing its eruption to cover covering about 30 communities with ash.

According to Wired’s Eruptions blog, the ash ranges from a light dusting to up to seven centimeters thick.

Popocatepetl means smoking mountain in Aztec. At 17,802 feet (5,426 meters) it is the second highest volcano in North America.

MSNBC reported that the eruption coupled with a plume of steam and ash and increased seismic activity, prompted authorities to raise the volcano’s alert status. Mexican authorities have since advised people to stay at least seven miles away from the summit.

Eruptions Blog author Erik Klemetti, a professor of geosciences at Denison University in Ohio, said that a raised alert level means that local authorities are preparing for potential evacuations should the volcano have a major eruption.

Fox News reported that the National Disaster Prevention Center said that a lava dome is growing in the volcano’s crater and that Popocatepetl could experience significant explosions of growing intensity that hurl incandescent rocks significant distances. Large ash showers and possible flows of mud and molten rocks down the volcano’s flank could also occur.

Albay gov bans activity near Mayon

TheABSCBNNews TheABSCBNNews

Published on May 6, 2013

Albay Governor Joey Salceda is banning all human activity within the six-kilometer permanent danger zone of Mayon Volcano after 4 climbers were killed during an ash explosion.

Salceda said the banned activities include climbing, farming, orchid gathering and ATV tour guides.

He said there was no warning of the steam explosion Tuesday morning but noted that a hard rain had affected the area on Monday.

Volcano tour guide Kenneth Jesalva, who went up the volcano with seven others on Monday, later said four people including 3 foreigners died after being crushed by large rocks brought about by the explosion.

FIVE people are feared dead after one of the Philippines’ most active volcanoes spewed a giant ash cloud, with foreign tourists on its slopes during the eruption, authorities said.

National Disaster Risk Reduction and Management Council chief Eduardo del Rosario said local officials reported that up to 20 climbers and guides, including foreigners, were on Mount Mayon when it erupted.

“Five killed and seven are injured, that is the latest report,” Mr del Rosario said. “We do not have the identity of those killed or injured, whether they are foreigners or locals.”

He said rescuers could not confirm firsthand the reported casualties until they reached the site.

Joey Salceda, governor of eastern Albay province where the 2,460-metre Mayon is located, gave the same number of casualties.

Marti Calleja, a local tour operator, said his company had sought help to rescue five foreigners who had gone to climb Mayon with his outfit’s guides shortly before the explosion.

“It rained like hell with stones. It was sudden and there was no warning,” Mr Calleja said.

The group was trapped about half a kilometre below the crater, Mr Calleja added.

Guide Kenneth Jesalva told ABS-CBN TV network by cellphone from a camp near the crater that the climbers died after being hit by huge rocks.

Philippine Volcano Spews Rocks, Killing 5 Climbers

 

One of the Philippines’ most active volcanoes rumbled to life Tuesday, spewing room-sized rocks toward nearly 30 surprised climbers, killing five and injuring others that had to be fetched with rescue helicopters and rope.

The climbers and their Filipino guides had spent the night camping in two groups before setting out at daybreak for the crater of Mayon volcano when the sudden explosion of rocks, ash and plumes of smokes jolted the picturesque mountain, guide Kenneth Jesalva told ABS-CBN TV network by cellphone.

He said rocks “as big as a living room” came raining down, killing and injuring members of his group, some of whom were in critical condition. Jesalva said he rushed back to the base camp at 914 meters (3,000 feet) to call for help.

Among the dead were three Germans and their Filipino guide, said Albay provincial Gov. Joey Salceda. He said everyone on the mountain had been accounted for at midday, except for a foreigner who was presumed dead.

Eight people were injured, and Salceda said the others were in the process of being brought down the mountain. Ash clouds have cleared over the volcano, which was quiet later in the morning.

“The injured are all foreigners … They cannot walk. If you can imagine, the boulders there are as big as cars. Some of them slid and rolled down. We will rappel the rescue team, and we will rappel them up again,” he said from Legazpi, the provincial capital at the foothill of the mountain.

An Austrian mountaineer and two Spaniards were rescued with small bruises, he said.

Tuesday’s eruption was normal for the restive Mayon, said Renato Solidum, the head of the Philippine Institute of Volcanology and Seismology.

Redoubt Eruption

We may be able to forecast volcanic eruptions a bit more easily. A new study has examined the sequence of seismic events that led up to the eruption of Redoubt and has discovered a little bit more about these explosive events.

We may be able to forecast volcanic eruptions a bit more easily. A new study has examined the sequence of events that led up to an eruption and has discovered a little bit more about these explosive events.

On March 22, 2009, the Redoubt volcano in Alaska erupted, spewing volcanic ash to an estimated 50,000 feet above sea level. These plumes of ash drifted through the skies before falling out of the air near Skwentna and the Chuitna area. Yet before this eruption took place, a series of seismic events occurred. It’s these events that researchers are interested in and which could potentially help scientists predict volcanic eruptions.

Well-established pre-eruption patterns can often include a gradual increase in the rate of seismic activity, a progressive alteration in the type of seismic activity or a change in ratios of gas release. In order to better understand these pre-eruption events, researchers examined the activity leading up to the 2009 eruption.

About six to seven months before the eruption, Redoubt began to experience long-period seismic events, as well as shallow volcanic tremors. These tremors intensified into a sustained tremor over the next several months. After this sustained tremor occurred, shallow, short-period earthquakes happened at an increased rate below the summit. About 48 hours before the actual eruption, researchers noted that both deep and shallow earthquakes rocked the land.

Mount Etna burst into life once more at the weekend as it shot lava, ash and smoke hundreds of feet into the air. Residents had been warned about the imminent eruption as grey smoke has been seen rising from the volcano for days. On Saturday, red hot lava was spat into the air as the volcano violently erupted once more. It is the thirteenth time Etna has erupted this year. Such is the scale of the activity that concerned residents have called on the Government to introduce a state of emergency. Experts said the latest activity posed no risk to local residents or towns. Stefano Gresta, president of the National Institute of Geophysics and Volcanology, said it was ‘very spectacular, but not risky’, according to youreporternews.it.

The airport was only briefly closed and the eruption caused very little disruption. The huge burst on Saturday could be seen by miles around and witnessed by residents of Catania and Taormina. Ash was sent flying down Etna’s slopes and smoke rose more than 3,000ft into the air. Locals said the latest eruption is the most ‘intense’ of the year so far. The eruptions ended shortly before midnight on Saturday, although further bursts of activity were recorded yesterday. A series of minor earthquakes, measuring up to 2.55 on the Richter scale were also recorded. Earlier this month, mayors of towns surrounding the volcano called for ‘urgent’ government action. In a joint statement, the politicians said they wanted a state of emergency to be declared. Mount Etna is Europe’s tallest active volcano. After past explosions, authorities in Sicily have been forced to build dams or dig ditches to divert lava away from people’s homes.
