Volcanoes Awakening Globally by Strong Seismicity

Popocatépetl volcano erupts again shooting ash 3km into the sky

The 5,426-meter stratovolcano, Mexico’s most active volcano, erupted overnight ejecting a large column of ash into the air and spewing lava.

The latest eruption forced the authorities to close Puebla airport, located east of the volcano, urging residents to wear masks and avoid inhaling volcanic ash.

About 25 million people live within a 100-kilometer radius of the active volcano.

Popocatépetl Volcano (“smoking mountain” in Aztec) is North America’s 2nd-highest volcano. The massive stratovolcano stands 5,450m high and lies about 65 kilometers (40 miles)  southeast of  Mexico City (19.023°N, 98.622°W) in the eastern segment of the Trans-Mexican volcanic belt.

Bezymianny Volcano on Russia’s Kamchatka peninsula erupts

Posted by msrb on August 20, 2008

PETROPAVLOVSK-KAMCHATSKY. The Bezymianny Volcano on Russia’s Kamchatka peninsula has erupted, Itar-Tass reported.

During the period of unrest, it emitted an ash column with a diameter of about 100 km.

The eruption was forecast prior to the unrest. The Bezymianny Volcano (2,800m high) is one of 28 active volcanoes on the peninsula. Bezymianny erupts explosively once or twice each year. The eruptions can last up to several days.

During its most powerful eruption in 1956, Bezymianny dome exploded collapsing about 280m of its summit (reduced from 3080 to 2800m). It ejected about one cubic kilometer volcanic debris in a very short time. [See VEI below.]

Volcanic Explosivity Index (VEI)

The Volcanic Explosivity Index (VEI) was devised by Chris Newhall of the U.S. Geological Survey and Steve Self at the University of Hawaiʻi in 1982 to provide a relative measure of the explosiveness of volcanic eruptions.

Chaitén Volcano Still Active

Posted by feww on May 14, 2008

*** Breaking News: May 19, 2008 Philippines Taal Volcano Could Erupt Anytime!

Update #2 Chaitén Volcano –

Chile President: Ash-Covered Towns Could Be Permanent Ghost Towns

A segment of the pyroclastic tower ejected from the Chaitén volcano has fallen on the surroundings areas amid the eruptive activities that began 8 days ago.

Chilean President Michelle Bachelet warned that towns surrounding Chaitén Volcano could become permanently uninhabitable. Bachelet’s remarks follows a report by National Geologic and Mining Service (SERNAGEOMIN) which forecast probability the volcano’s collapse at more than 50 percent.

The increased build-up of pyroclastic material in the magma dome made it prone to collapse, SERNAGEOMIN said. An implosion could result in the “complete destruction of everything within a 15 kilometer radius around the peak, an area which encompasses Chaitén, Santa Barbara, and several rural farming villages.”

According to vulcanologist Luis Lara Chaitén volcano could implode releasing a streams of red-hot pyroclastic material which would destroy everything in its path. (Source)

Chile: Volcano activity prompts mass evacuation

Volcanic Activity prompts Mass Evacuation

Thousands of people in the Patagonian community of Chaiten have been evacuated a day after a volcano spewed smoke and ash, its first eruption in about 10,000 years.

The Patagonian township of Chaiten covered in thick-ash, resembled a ghost town on Saturday after thousands of its inhabitants fled the region.

The snow covered 1,200-meter Chaiten volcano spewed a combination of smoke, ash and fire Thursday night, causing small tremors in the Los Lagos region, about 1,200 kilometers south of Santiago.

Chilean government declared a state of emergency, evacuating the residents from nearby villages and the township of Chaiten,which is situated about 10 kilometers from the volcano.

The falling ash is polluting the water supplies and making breathing difficult prompting the authoruities to hand out about 10,000 protective masks.

The Chaiten volcano has “probably been dormant for about 9,000 or 10,000 years but that’s not unusual,” according to a professor of volcanology at the University of Colorado who specializes in the Andes volcanoes.

“I would really worry about the village of Chaiten. I think they would want to get everybody out of there really soon,” he said.

“In southern Peru, the Ubinas volcano shot out gases and ash twice on Friday, covering local homes and crops. There were no immediate reports of injuries.” (Source: Shanghai Daily )
