Pavlof and Cleveland volcanoes erupting in Alaska

Astronauts aboard the International Space Station (ISS) photographed this striking view of Pavlof Volcano on May 18, 2013. 

The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites. 

Situated in the Aleutian Arc about 625 miles (1,000 kilometers) southwest of Anchorage, Pavlof began erupting on May 13, 2013. 

The volcano jetted lava into the air and spewed an ash cloud 20,000 feet (6,000 meters) high. 

When photograph ISS036-E-2105 (top) was taken, the space station was about 475 miles south-southeast of the volcano (49.1° North latitude, 157.4° West longitude).

Guatemala Volcano Erupts, 33,000 Evacuated: Erupting Volcano Del Fuego

Guatemala Volcano Erupts & 33,000 Are Evacuated: Photos Of Erupting 'Volcan Del Fuego'

The Guatemala volcano "Volcan del Fuego" erupted Thursday, forcing some 33,000 locals to flee the area, emergency services said.

Ash and smoke were spewed into the sky as the volcano began to erupt. The volcano lies 25 miles southwest of Guatemala City and began to send a cloud of ash into the sky in the early afternoon, Sergio Cabanas, director of emergency response in Guatemala's CONRED emergency agency, told Reuters.

Nearly 8,000 people have already been evacuated and almost 23,000 are awaiting evacuation, he added.

Guatemala has four active volcanoes, Reuters said, and the 2010 eruption of Pacaya covered 25 miles of Guatemala City with ash. Airports were closed and hundreds of families were evacuated.

Cabanas additionally said that 17 villages near Guatemala City were evacuated in the biggest such operation the country has ever seen.

Although the volcano is just six miles from Antigua, a popular tourist destination, Antigua was not in the evacuation zone according to NBC News.

The "Volcano of Fire" has spewed lava that billowed 2,000 feet down its slope, BLIPPITT reported.

"A paroxysm of an eruption is taking place, a great volcanic eruption, with strong explosions and columns of ash," Gustavo Chicna, a volcanologist with the National Institute of Seismology, Vulcanology, Meteorology and Hydrology, said to BLIPPITT.

He said the ash from the volcano was nearly half an inch thick in some areas and the government's disaster agency added that homes and buildings were covered with ash miles away.

This is the fifth time Fuego has erupted this year, but its biggest eruption since 1999, a Guatemalan scientist told NBC News.

Teresa Marroquin, a Guatemalan Red Cross coordinator, told NBC News that the group has set 10 emergency shelters and is sending hygiene kits and water.

"There are lots of respiratory problems and eye problems," she said.

Chinca added that "it's almost in total darkness" near the living mountain.

Galactic 'Supervolcano' Seen Erupting With X-Rays

A galactic "supervolcano" in the massive galaxy M87 is erupting, blasting gas outwards. The cosmic volcano — driven by a giant black hole in M87's center — is preventing hundreds of millions of new stars from forming.

"Our results show in great detail that supermassive black holes have a surprisingly good control over the evolution of the galaxies in which they live," said Norbert Werner of the SLAC National Accelerator Laboratory in Melo Park, Calif., who led one of two studies of M87's black hole and its effects. "The black hole's reach extends ever farther into the entire cluster, similar to how one small volcano can affect practically an entire hemisphere on Earth."

X-ray galaxy

M87 is about 50 million light-years from Earth and lies at the center of the Virgo cluster, which contains thousands of galaxies. M87 is filled with hot gas that emits X-ray light, which is detectable by Chandra. As the gas cools, it can fall toward the galaxy's center, where it should continue to cool even faster and form new stars.

Yet, radio observations from the Very Large Array suggest that in M87, jets of very energetic particles produced by the black hole interrupt this process. These jets lift up the relatively cool gas near the galaxy's center and produce shock waves in the galaxy's atmosphere from their supersonic speed.

Scientists have found that the interaction of this cosmic "eruption" with the galaxy's environment is very similar to volcanic processes on Earth. In particular, the researchers compared it to the aftermath of the Eyjafjallajokull volcanic eruption, which forced much of Europe to close its airports earlier this year.

The energetic particles produced near the black hole rise through the X-ray-emitting atmosphere of the cluster, lifting up the coolest gas near the center of M87 in their wake, similar to the way hot volcanic gases drag up clouds of dark ash.
