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.

Alert status at the Philippines' Taal raised

April 8, 2011, 11:46 PM
Taal

Very brief update as I spent all day in the Department of Geological Science at Michigan State and gave a talk so, I'm a bit exhausted (but thanks for a nice visit). However, I did see this news on Taal: PHIVOLCS has raised the alert status at the Philippine caldera to Level 2 and warned of the potential of an eruption. The evidence of a potential eruption include:

  • Increasing seismicity that appears to also be getting shallower, with 21 earthquakes in the last 24 hours, all within 1-4 km of the surface (and some directly under Volcanic Island in the Taal caldera lake.
  • Carbon dioxide emissions have risen to 4,760 tonnes/day in late March, a four-fold increase from a month earlier.
  • The volcano has inflated in February.
  • Steaming has intensified at vents in the caldera as well.

All of these signs have PHIVOLCS concerned (and rightly so) that magma might be rising towards the surface. The Philippine government has put the Main Crater, Daang Kastila Trail and Mt. Tabaro off limits as a result of this increased alert status.

Taal has been restless for the better part of a year now, but no eruption as occurred there since 1977 - if you're curious about the results of a potential eruption, please check of the PHIVOLC hazard map for Taal. The volcano sounds like it is well worth watching if these indications of an eruption continue.
