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.

GVP Weekly Volcanic Activity Report for September 29-October 5, 2010

October 7, 2010, 11:11 AM

New reports of volcanic activity from around the world! Thanks again to Sally Kuhn Sennert for putting together these reports for the Global Volcanism Program.

Some highlights:

Colombia It was a busy week, volcanically-speaking, in the South American nation. We're talked about Nevado del Ruiz and the GVP mentions that the volcano has also shown changes in "deformation and geochemistry", which for the latter I assume means from the gases being released (but it could be water as well). Over at Nevado del Huila, the active summit dome produced plumes that reached up to 7.5 km / 25,000 feet along with incandescence and hot rock falls as part of a partial dome collapse (spanish).

Chile Planchon-Peteroa continues to produce ash plumes that reach as high as 3-6 km / 10-20,000 feet. Changing winds have raised considered of ash fall (spanish) in communities near the volcano, but ONEMI says there is no real danger (spanish). The volcano remains on Yellow Status - you can check out the latest SERNAGEOMIN report here (spanish - follow Region del Maule - Reportes - 2010)

Guatemala Fuego continues to experience explosions - and even an occasional lahar. This continues the pattern from earlier this summer. Pacaya also produced weak steam plumes as part of its continuing activity.

Kuril Islands It has been a while since we talked about Sarychev Peak - a big newsmaker in 2009 - but the volcano does continue to be active. Ash plumes were detected from the island volcano by satellite. Currently, remote sensing by satellite is the only monitoring for the remote volcano, which lacks any seismic monitoring.
