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.

Seismicity increases at Machín in Colombia

December 8, 2009, 6:12 AM

I just picked up on this story over on the Volcanism Blog, but I want to post it here too. Machín, in Colombia, has experienced a sharp increase in seismicity at the volcano - maintaining the Yellow status for the volcano. 54 earthquakes were recorded at the volcano over the weekend, prompting the INGEOMINAS to raise the alert status. The volcano had a swarm in 2008 that did not lead to any eruption - but remember, better to be safe than sorry. If Machín were to erupt, it would join Galeras and Huila as erupting volcanoes in Colombia.

Not much is known about Machín, located only 22 km / 14 miles from the city of Ibagué (pop. ~500,000). The last known eruption (well, dateable eruption) was in ~1180 A.D. (+/- 150 years) and over the last 4,000 years, the volcano has produced at least seven eruptions. Typically they are explosive events, producing ash falls, pyroclastic flows and lahars - par for the course for the Colombian volcanoes.
