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.

Wednesday Whatzits: Redoubt returns to normal and swarms at Long Valley

September 30, 2009, 4:31 AM

The big geology news right now is the M8 earthquake in American Samoa that generated a killer tsunami (which made it all the way to the Bay Area in California).

Mammoth Mountain in California's Long Valley region.

In more benign, volcano-related news:
  • The aviation alert level at Redoubt in the Alaska has been returned to Green/Normal, which means that for all intents-and-purposes, the eruption that started earlier this year is over. The new dome totals ~91 million cubic yards of lava, slowly adding back to the north side of the volcano.
  • Eruptions reader Doug C. pointed out to me that there was a couple small earthquake swarm (see the update for 9/28/2009 and 9/29/2009) this week at Long Valley/Mammoth Mountain in California. The earthquakes were all fairly small, in the M1 range - and deep, at ~20 km / 12 miles depth. Just shows that there might be magma burbling around down there somewhere, but this doesn't seem like much beyond some transient noise (and the alert level stays at Green/Normal).
