What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Large eruption at Karkar in Papua New Guinea?

November 25, 2009, 12:13 PM


Karkar volcano as seen from space.

Eruptions reader The Bobs left a note mentioning that there may have been a 'significant' eruption at Karkar in Papua New Guinea. The only place I can find information is John Seach's Volcano Live:

An eruption occurred at Karkar volcano at 6:39 pm on 25th November 2009. The eruption plume reached a height of 45,000 ft. A magnitude 5.1 earthquake hit 90 km SSE of Karkar volcano 7.5 hours before the eruption.

I don't know too much about Karkar, but the GVP says that it is a volcanic island made of a pair of calderas, with the inner caldera formed in the last 1,500 years. Volcano Live mentions a 1997 activity at the volcano (in the form of fumarolic activity), but the GVP lists the last eruption as occurring in 1980. Most eruptions look to be fairly explosive (~VEI 2) from the pyroclastic cone in the inner caldera. Weekly volcano reports from the SI/USGS lists some fumarolic activity from the inner caldera in January 2008.

If the reports are accurate for this new activity, it could definitely be a "significant" eruption. More news as I can find it.

UPDATE 5:30PM 11/23/2009: And more information is found, over at the Volcanism Blog.

UPDATE 6:45PM 11/23/2009: This isn't really an update as such, but I did stumble across these TOMS images of SO2 from a 1979 eruption of Karkar.
