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.

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 the changes in temperature, rainfall, ice mass, sea level, and many other variables recorded by weather measuring devices. The trends are undeniable: the Earth is […]
In July of 2012, the Haida Salmon Restoration Corporation in conjunction with American businessman Russ George, carried out an audacious and completely unauthorized ocean fertilization experiment. Approximately 100 tonnes of iron sulfate were spread across the surface of an ocean eddy, some 300 kilometers off the west coast of Canada’s Queen Charlotte Islands. When details of […]
Some volcanoes ‘scream’ at ever-higher pitches until erupting — the ‘scream’ being the harmonic tremors that often accompany the earthquakes which typically precede volcanic eruptions, according to new research from the University of Washington and the USGS. The new findings are the result of a new analysis of the March 2009 eruption of Alaska’s Redoubt […]
The two most active volcanoes in Alaska (in recent years) — Pavlof Volcano and Cleveland Volcano — are now both erupting. As of now, the activity is at relatively low levels, but the potential is there for larger eruptions, or a general intensification of activity. Mount Pavlof (Pavlof volcano) is situated near the western end […]
The beautiful nearly-symmetrical Cleveland Volcano in Alaska has now awoken again after a short rest, last erupting in 2011. The remote stratovolcano began erupting on Saturday with a series of three large explosions and has since then been releasing a continuous plume of ash, gas, and steam, into the atmosphere. These releases, particularly the ash, […]
There have been two types of volcanic eruptions for some time now – explosive or effusive. An explosive eruption is marked by a violent and explosive eruption, such as the Mount St. Helens eruption of 1980. An effusive eruption is marked by the outpouring of lava onto the ground. However, new research has uncovered a previously undocumented type of eruption […]
New studies conducted by researchers at the U.S. Geological Survey have found that tsunamis pose a risk to the East Coast of the United States. Researcher Uri ten Brink noted that, “although the risk is small,” a variety of sources could actually trigger a tsunami on the East Coast. Brink also stated: “Hurricane Sandy showed […]
The volcano that was featured as Mount Doom for the Lord of the Rings trilogy is causing the New Zealand Department of Conservation some angst, with department measurements indicating the increasing likelihood that Ruapehu will erupt. Subsequently, the Department of Conservation issued a warning to climbers and trampers in the region, recommending that they do not […]
An international team of researchers has just discovered that aerosols even from comparatively small volcanic eruptions can make it into the high atmosphere when assisted by weather systems such as monsoons. Once in the high atmosphere, aerosols are capable of affecting global temperatures for a short time. If they don’t make into into the […]
An undersea volcano located 250 miles off the coast of Oregon gave off clear warning signals just hours before erupting last year, according to researchers from Oregon State University. The research is from the same team that correctly predicted the eruption of the same volcano, years in advance, before its 2011 eruption. The researchers had […]
Super-volcanos form and erupt much more quickly than previously thought, according to a new study from researchers at Vanderbilt University. Super-volcanos and super-eruptions are referred to as super because of their massive scale, more than 100 times the size of an eruption like Mount St. Helens. They release tremendous amounts of gas, ash, and […]
A new forensic approach that links changes deep within a volcano to surface observations has just been described by scientists in a new study published in Science. The research may help develop volcanic prediction of great accuracy. Using chemical analysis the researchers directly linked seismic observations of the Mt. St. Helen’s eruption in 1980 […]
There is growing evidence that some of the Earth’s most catastrophic geological events were triggered by changes in the climate. The melting of ice sheets and changes in sea level served as triggers to some of the world’s largest earthquakes and volcanic eruptions, according to British geologist Bill McGuire. The best evidence of climatic […]
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.
Why Are We Fascinated with Short-term Destruction & Fear (i.e. Volcanoes, Rapture) but Oblivious to Long-term Harms (i.e. Global Warming)?
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.
