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.

Eruption Updates: Bulusan, Lokon-Empung and Kilauea

A couple quick updates on new and ongoing eruptions:

Lokon-Empung, Indonesia: Eruptions reader Ton Van Der AA brought us news about a small, new eruption at Lokon-Empung (Indonesian) in Indonesia. Ruskanda Farid of the local volcano observatory described the eruption as a phreatic event - a stream-driven explosion that shattered old rock at the summit of the volcano. The report mentions increased seismicity and higher temperatures at the summit crater as well. Lokon-Empung, which is actually twin volcanoes called Lokon and Empung (see top left), typically produces VEI 2-3 explosive events every few years, with the last eruptive episode happening in 2003.

Bulusan, Philippines: People have begun to leave the area around Bulusan after the explosions of earlier this week, including 2,000 people moved by the army. This comes with warnings from PHILVOLCS geologist Ed Laguerta that the ash from the eruption might trigger lahars if there is increased rainfall. The ash fall from this and other eruptions have already caused problems with the farmers whose livelihood depends on crops located on the slopes of Bulusan, along with reports of respiratory issues in towns near the volcano.

Kilauea, Hawai`i: We've been following the increased activity at Pu`u O`o and the Halema`uma`u Crater over the last few weeks. The most recent HVO update on Kilauea mentions that a new cycle of inflation started Monday evening. The deflation period that ended at 9:15PM on 2/21/11 was the largest amplitude and longest duration event at Kilauea since 2000. However, the switch back to inflation might suggest a new period of vigorous activity is coming soon.

As always, be sure to check out the available webcams for these volcanoes to see the action.
