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.

More details on the Ethiopian eruption

November 6, 2008, 8:36 AM

Sounds like we're beginning to get a better idea of what is erupting in Ethiopia. Ghezahegn Yirgu, a geologist at Addis Ababa University, reports that Dalla Filla Dalaffilla Volcano is the source of the eruption. Again, the eruption is being characterized as "lava flows" rather than an explosive eruption, which may be surprising considering the amount of volcanic gases being released (see Boris Bechnke's highly useful comment). However, some mostly effusive eruptions have released a lot of volcanic gases in the past - see Laki, Iceland in 1783 - so a preponderance of flows at Dalla Filla Dalaffilla would not be shocking. 

Now, there is surprisingly little information I can find about Dalla Filla - in fact, it doesn't even appear in the GVP database or, for that matter, almost anywhere on the internet. The volcano is located, according to the article linked above, about 20 km north of Erta Ale, so it is in a region of active East African Rift volcanism. The map above (from the USGS) shows all the volcanoes in the area that have known eruptions since 1800, so unless Dalla Filla is being confused with Dallol, it might be the first eruption of the volcano in quite some time. I'll update once I can find more information on Dalla Filla (and feel free to comment here if you know more than I).

REVISED (11/6/08): Apparently, the volcano in question is Dalaffilla, which shows up in the GVP website (Thanks Ole and Ron). There isn't much information on Dalaffilla, except that, surprisingly, it appears to be a silicic volcano. The reports I've read so far seem to indicate that lava flows have spread out over a large area, which would suggest a low viscosity (i.e., basaltic) lava. Thanks to the Eruptions readers who dug out some great information.
