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.

Friday Flotsam: Back from break with Kamchatka, Bulusan and Etna

December 31, 2010, 11:24 AM
Kizimen

I am back from my break - it was a good time in New England, even with the Snowicane that kept us at home for a couple days. I definitely needed the break and considering how little I actually thought about geology most of the time, I think it was time well spent. Now, I just need to start getting my act back together to actually start 2011 on the right foot. I thought for today I'd try to catch up a little bit with any news I missed (well, at least some of the news I missed) and then look for the announcement of the 2010 Pliny for volcanic event of the year on Monday. You still have time to make your voice heard for the 2010 Pliny - so head over and leave your comments/votes for the award.

Some updates!

Kamchatka: Sounds like looking at your comments over my vacation that Kamchatka was being noisy as usual. The latest USGS/SI Volcanic Activity Report did have plenty to sat about Kizimen, Shiveluch and Karymsky. All these volcanoes produced some sort of explosive eruption over the past week, including a 4-km ash plume at Karymsky. Most recently, the activity at Kizimen has been downgraded to "Orange" from "Red", but the NASA Earth Observatory posted a great image of the swirling ash over the volcano on December 30 (UPDATE: and here is another from December 31). Speaking of the Kamchatkan volcanoes, I had neglected to post anything about a recent article I saw about using lightning to detect ash clouds before they show up on radar or satellite images - sounds promising and Kamchatka is a great location to test the tool.

Philippines: Bulusan also made a little noise over my vacation, with a few small explosions reaching ~500 meters / 900 feet and an slight uptick in seismicity. The latest report from PHILVOLC says that the volcano experienced 8 earthquakes over the last day but much of the summit area has been obscured by clouds, so any hope of seem small explosions is limited. The volcano remains at alert status 1 with a 4-km "no entry" zone around the volcano.

Etna/Stromboli: And with Dr. Behcke has been keeping us so well appraised, I sometimes forget to post about the activity in Italy, including small explosions and earthquakes at both Etna and Stromboli over the Christmas holiday. There are some great thermal images made of the explosions from last week on the INGV Catania website where you can see the plume of material bursting from the crater during each event.

Have a safe and happy New Year's (i.e., don't climb into Mt. Bromo) and I'll see you all in 2011!
