What Causes Global Warming?

Droughts, lengthy hot spells, heavy downpours, floods, and other extreme weather events are occurring more frequently and intensely every year. Around the world, research teams are analyzing these trends, noting … [Read full article]

Supervolcanoes Will Not End Earth in 2012, Probably

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.

Ancient Lake Linked to San Andreas Earthquakes

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.

Image Down Center of Erupting Nabro Volcano

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.

Nabro Volcano Before Eruption {Photo of the Day}

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.

NASA Shows Chilean Volcano Plume Moving Around the World

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.

Images of Grímsvötn Volcano Eruption

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.

Iceland Volcano Causes Flights of Thousands to be Cancelled

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.

Iceland Volcano Eruption Continues, Volcanic Ash May Hit UK, France, Spain

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?

Grímsvötn Volcano Eruption 2011 {4 VIDEOS}

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.

Iceland Volcano, Grimsvotn, Erupting (not Rapture, but hey..)

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.

Deep Sea Volcanoes Explode Too

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.

Volcanic Activity at Kilauea

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.

Japan Earthquake Triggered Volcano Eruption In Russia?

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.

Mount Etna Erupts

On the 11th of January, Mount Etna, in Sicily, Italy, Europe’s largest volcano, erupted briefly, spewing flames, ash and smoke into the atmosphere and lava down its slopes. The ESA’s … [Read full article]

Volcanoes: The 'X Factor' in Climate Change

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.
