The USGS estimates that 10 million tons of CO2 was released over the 9 hour eruption of Mount St. Helens in 1980. That’s a pretty huge number, but passenger vehicles in the USA alone emit as much CO2 as a Mt St. Helens eruption happening somewhere in America every 3 days.

In what life was probably like prior to the coming of the year 2000, every man and his dog is coming up with a theory for how the Earth will end come 2012. After already curbing fears that a giant “killer solar flare” will wipe out planet Earth next year, NASA has again weighed in, this time explaining that a supervolcano will not have a supereruption during 2012.
Probably. Let’s get to that later.
Scientists who witnessed the eruption of a deep sea volcano during a 2009 expedition report that the volcano was taking place near a tear in the planetary crust that is mimicking the birth of a subduction zone.
Mount Tambora, the volcano that caused the most deaths in known history (71,000) may explode again soon…
One of the tallest and one of the most active volcanoes in the world, Mount Etnain in Sicily is erupting again, spewing lava and ash into the air.
Hawaii’s Kilauea volcano had an eruption and lava overflow this week. For more, check out the Guardian video below:
Southern California’s Salton Sea may be one of many factors involved in setting off earthquakes in the region, specifically along the southern San Andreas Fault, and may in fact have already triggered large earthquakes over the past thousand years.
These two photos – one false-colour the second natural-colour – are some of the first detailed pictures of the erupting vent and lava flows from the Nabro Volcano, located along the border between Eritrea and Ethiopia.
After midnight local time on June 13, 2011, the Nabro Volcano in the Southern Red Sea Region of Eritrea erupted after a series of earthquakes hit the Eritrea-Ethiopia border region, ranging up to magnitude 5.7. The image below shows what the stratovolcano looked like before it erupted.
In early June the Chilean Volcano called Puyehue-Cordón Caulle erupted, sending a massive plume of ash around the Southern Hemisphere, stalling flights out of many airports and causing havoc for millions of passengers. NASA Satellite imagery captured the plume as it made its way around the world.
Below, are images from the eruption and of the ash plume that ended up disrupting air travel in Iceland, followed shortly by Greenland, Scotland, Norway, Svalbard and a small part of Denmark, Northern Ireland, northern England and Northern Germany.
Despite the news yesterday that, due to improved volcanic ash safety regulations and differences in the weight of volcanic ash from Grimsvotn compared to Eyjafjallajökull, flight cancellations and disruptions from the Iceland volcano Gromsvotn were likely to be minimal, it seems that the volcano is affecting flights in Europe now.
The Grimsvotn volcano continues to erupt at the same levels as it has since Saturday, the eruption is reportedly “much bigger and more intensive” than Eyjafjallajökull eruption last year and 10 times bigger than Grimvotn’s eruption in 2004. However, it is not expected to have nearly the same effect as the Eyjafjallajökull eruption (and the 2004 Gromsvotn eruption had little effect). Why?
I covered the eruption of the Grimsvotn volcano in Iceland last night as the news broke and just wrote an update on the status of the eruption and a local flight ban that has been instituted. BUT, I know what you all really want — VIDEOS.
I reported last night that the Grimsvotn Volcano eruption in Iceland yesterday was unlikely to cause much chaos for international flights. News is now that Iceland’s authorities are putting a temporary flight ban in place, but that the same prediction remains.
Yeah, this is something I’ve thought about a lot, and read psychological articles on — it’s not new. But with the eruption of the Icelandic volcano, Grimsvotin, on top of the hysteria (or mocking of hysteria) regarding Rapture, this question has flooded my thoughts and left me in wonder again.
Iceland’s most active volcano, the Grimsvotn volcano, has erupted, MSNBC reports. 18,000-foot high white plumes have shot into the air, according to scientists. 50 or so small earthquakes (the largest of which was 3.7 on the Richter Scale) followed.
Over the last decade, geologists have speculated that based on certain evidence in the surrounding environment, these undersea volcanoes are capable of explosive eruptions. No one’s been able to prove it though. Until now.
One of Earth’s most active volcanoes, Kilauea, surged to life on March 5 of this year, spewing fresh flows of lava out the opening of a new fissure and starting off a forest fire that has burned for much of this month. NASA’s Advanced Land Imager (ALI) onboard the Earth Observing-1 (EO-1) satellite captured the following false-color images of the area.
One of Indonesia’s most active volcano’s has erupted, sending lava and searing gas clouds tumbling down its slopes.
The major earthquake that just hit Japan, may have just triggered the some volcanoes in Russia. While reports are still vague on the incident there is a strong correlation between the two incidents. In Russia there are reports that earthquakes where felt during the eruption.

Apart from the major disruption in flight traffic and the economy, the Icelandic volcano eruption promises in the short-term to disrupt upper atmospheric circulation patterns and temperatures, with an additional impact due to sulfuric acid “nucleation” and subsequent acid rain. But the medium to long-term impacts of continuous, or increasing, volcanic eruptions is a matter of on-going scientific debate.
