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.

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.

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 […]

  Super-volcanos form and erupt much more quickly than previously thought, according to a new study from researchers at Vanderbilt University.

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?

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.

But the medium to long-term impacts of continuous, or increasing, volcanic eruptions is a matter of on-going scientific debate.
