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.

Another sizable earthquake in Christchurch, New Zealand

February 21, 2011, 8:11 PM

Last year, the city of Christchurch in New Zealand experienced a M7.2 earthquake. Luckily that earthquake was centered in a relatively unpopulated area outside the city in the middle of the night. On Monday, however, a potential aftershock of the September 2010 earthquake struck closer to the city during midday, a potentially much more dangerous mix. The new earthquake was a M6.3 (preliminary) at ~5 km depth and initial reports of the earthquake suggest a lot of damage in the city (top left and below). There is already some impressive video that seems to have captured one of the aftershocks of this new earthquake as it happened as well. You can see the webicorder of the region here as well. GNS New Zealand does have an excellent image showing the shockwave of the earthquake as it was received across the country (see below) - the stations are listed north (top) to south (bottom), with the signal from the main earthquake and aftershocks.

More updates as I find them ... and please post any you find as well. Until then, let's hope that this earthquake isn't as bad as it seems it could be.

UPDATES (note, you can see a running news feed from the NZ Herald)

More UPDATES:

Sadly, this new earthquake in Christchurch brings home some very important lessons when it comes to earthquakes: (1) magnitude doesn't control the level of destruction; (2) location and depth of the focus are vital for understanding the level of destruction; (3) time of day can greatly effect the casualties in an earthquake. Had this earthquake struck during the night like last September's earthquake, the death toll might have been smaller - individual homes tends to survive better than larger office or professional buildings. Truly a sad day for New Zealand.
