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.

Yet another Indonesian volcano on alert - Mt. Rinjani (Barujari) - UPDATED

Sometimes it is hard to appreciate how many volcanoes lie within Indonesia. However, within the last few weeks, no less than four Indonesian volcanoes have been put on alert to eruption or shown increased signs of activity - Slamet, Kirinci, Anak Krakatau and now Mt. Rinjani (above).

UPDATE 5/3/2009 11AM (Pacific)
: The volcano is erupting according to the Jakarta Globe. Seems like the activity so far is confined to small explosions emitting ash and gases. More info as I find it.

Rinjani is a popular tourist destination on the island of Lombok and lies within the Segara Anak caldera (see below). Half the caldera is filled with a lake and on the east side is Mt. Barujari - this is where the current alert is centered. Seismicity has increased and a team of scientists from the Mining and Mineral Resource office will visit the volcano to assess the situation. The volcano is part of the Mount Rinjani National Park and park officials have now closed off the area near Mt. Barujari from tourists.

Barujari last erupted in 2004, producing explosions from the central and flank vents. You can see lava flows from previous eruptions flowing out into the lake on the satellite image of the caldera (below), such as happened in 1966.
