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.

Kirishima eruption in Japan still going strong

January 27, 2011, 8:39 AM

I had a fun time last night speaking to the Licking County Rock and Mineral Club - lots of talk about volcanoes and we spent some time talking about our newest best friend, Kirishima. The impressively-erupting Japanese volcano (see below) has finally made it into the english-speaking media but not in the way I expected. No, many of the articles I saw were referring to the eruption as from the "James Bond" volcano, which at first elicited a "huh?" from me but then realized that yes, indeed, Shimnoe-dake cone was a model for the evil lair of the villain from "You Only Live Twice". Leave it to the news to think that a tie-in to the Bond film is the interesting angle for this event. (Sigh … well double sigh for the articles that call it "smoke" coming out of the vent.)

The volcano is still erupting, producing a significant plume - you can check it out on the Kirishima webcam from the JMA (seventh volcano from the bottom on the right-hand menu). We also have on-the-ground reports from intrepid Eruptions reader and volcano-chaser James Reynolds who is headed to the volcano to see the action firsthand. He reports a lot of ash fall in the southern region of Kyushu. Sei Iijima of Japanese Meteorological Agency, the body that monitors volcano activity, says that this eruption is not a danger to any cities in the region (beyond the nuisance of ash) and that the seismicity at the volcano suggests that no larger event is on the way, however, the eruption as it is may continue. The JMA is characterizing this as a "small eruption" of the volcano and the current alert status prevents people from going within 2 km of the volcano. In fact, no evacuations have even been issued due to this eruption (although some people left on their own). Most of the problems caused by the eruption have been disruptions to air, train and road traffic in and around the area around Kirishima on Kyushu. The plume from the volcano shows up as a small puff on the IR satellite loop for the region as well as the ash continues to cause a VAAC advisory for up to 7.5 km / 25,000 feet. You can an even get an ideal of the sulfur dioxide released in the eruption from this GOME-2 image over the Pacific Ocean (see below) taken earlier today.

There is still lots of great video of the eruption from yesterday and today, including timelapses of the events from two webcams. So far, this eruption is another ideal volcanophile event where life/property seem to be fairly safe, but there are still lots of eyes trained on the volcano to see all the events unfold. I will update with any news from this eruption as it happens today.
