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.

Ash explosions from Bromo and Anak Krakatau in Indonesia

January 27, 2011, 9:45 AM

If the eruption at Kirishima wasn't enough to keep us occupied, Bromo in the Tengger Caldera has ramped up its activity significantly. Last fall, the volcano had a few explosive events that disrupted air travel near the volcano but all of Bromo's activity was overshadowed by Merapi. Earlier this year, we got some snaps of the area near Bromo from Dr. Philipp Ruprecht, showing both the ash fall from the previous eruptions and the strong plume from the vent. It appears that new ash eruptions have started to issue from Bromo - and along with these lava flows cam enough ash to divert flights headed towards Bali. The Darwin VAAC has issued an ash advisory for a large swath of the Indian Ocean to the south-to-southeast of Bromo up to ~5.5 km / 18,000 feet. It sounds from the reports that internationa flights are not likely to resume for at least another 24 hours but domestic flights are unaffected. The description of the eruption sounds like strombolian-style explosions that have reached ~200 meters, but the details are scant.

In a little older news, another Indonesia volcano has been erupting explosively over the last week as well. You can see a bunch of up-close-and-personal video of eruptions at Anak Krakatau from last week (January 20), showing the strombolian rumblings at the volcano. PVMBG, the volcano monitoring body in Indonesia, has Bromo at orange alert status and Anak Krakatau at yellow. Indonesia definitely continues to be a busy place for erupting volcanoes (which is no great surprise).

UPDATE: Here is a video of the current activity at Bromo (link courtesy of Eruptions reader Sherine)
