Beautiful Sunsets Due to Sarychev Peak Eruption

July 1, 2009

The Sarychev Peak eruption, captured by the International Space Station on June 12th, is causing “volcanic lavender” sunsets across Europe and the northern United States.  The Sarychev Peak Volcano blew massive plumes of sulfur dioxide (SO2) and other debris into the stratosphere creating the effect.

Here is the amazing picture of the June 12th eruption taken from the ISS:

Scientists are very excited to have this rare image  in order to learn more about the early stages of powerful volcanic eruptions.

Here is an image of the sunsets the eruption is causing:

Supervolcano Under Mount St. Helens?

According to research by New Zealand scientists, Mt. St. Helens could be a supervolcano.  These scientists believe that Mount St. Helens, Mount Rainier and Mount Adams appear to be linked by a deep column that leads to a pool of what could be molten rock.  This could mean is that all the volcanoes work together to form one supervolcano, with Mt. St. Helens at the center.  That would make it one of the largest supervolcanoes in existence, equivalent to the supervolcano under Yellowstone.  Such a supervolcano would have the potential of a world-changing cataclysmic eruption.   For more information, see the New Scientist.

La Cumbre Erupts in Galapagos Islands

La Cumbre volcano on uninhabited Fernandina Island, one of the Galapagos Islands, began erupting on Saturday after nearly fours of inactivity. While the volcano is not a threat to inhabitants on nearby Isabela Island, it is a threat to the unique wildlife of the Galapagos.  Charles Darwin visited the Galapagos during his voyage on the HMS Beagle and its unique species helped him formulate his theory of evolution.  For more information on the eruption, see here.

Saturday Eruption at Mt. Redoubt

Another significant eruption on Saturday signals that Mt. Redoubt is showing no signs of stopping.  An ash cloud was sent 50,000 feet into the air.  Typically, when Mt. Redoubt enters an eruption phase, it erupts for months.  So, Alaskans are likely to experience many more eruptions by Mt. Redoubt.

First, Mt. Redoubt continued to erupt several times on Saturday, March 28, sending volcanic ash to Anchorage, 100 miles to the northeast.  The ash plume was 45,000 to 50,000 feet high on Saturday.  After the first eruption, there was also strong seismic activity.  The Ted Stevens Anchorage International Airport shut down due to the ash, but reopened on Sunday and is expected to be fully operational on Tuesday.  On Sunday, Mt. Redoubt did not erupt, but it did have low-level tremors.   For more information, see the Associated Press article here.

Second, the Space Shuttle Discovery landed in Florida on Saturday, ending its 13 day mission to the International Space Station (ISS).   Discovery brought Dr. Sandra Magnus back to Earth after four months in space at the International Space Station.  She was replaced aboard the ISS by Koichi Wakata, a Japanese astronaut, who arrived via Discovery. Additionally, a Russian Soyuz capsule with an American tourist on board has docked safely at the International Space Station just a few days after Discovery’s departure.  For more information, see here.

Mt. Redoubt erupted twice this morning again.  The second eruption was described as a major event and sent ash 12 miles into the air, the highest ash plume so far since Mt. Redoubt came to life on Sunday night.  For more information, see here.

Eruptions at Mt. Redoubt Again

Mt. Redoubt erupted twice on today, once around 5:00 am and then again around 10:15 am.  These blasts were much smaller and more brief than the eruptions on Sunday and Monday.  The Alaska Volcano Observatory has lots of interesting information on Mt. Redoubt and other Alaska volcanoes available here.
