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 at Gaua

October 16, 2009, 4:39 AM

A 1995 photo of Gaua volcano in Vanuatu.

A few weeks ago I mentioned that there were signs that Mt. Garet, part of the larger Gaua volcano in Vanuatu was potentially showing signs of a eruption - the first since 1982. It turns out that the rumbling and sulfur odors reported by local residents were correct and it appears that Gaua did indeed erupt. The latest report from the Geo-Hazard section of the Department of Geology, Mines and Water Resources in Vanuatu:

After the assessment of the Geohazards team on Gaua volcano from 3-7 October 2009, it is confirmed that Mont Garet volcano is going through an eruptive phase starting from the 27th of September 2009. Seismic records of the seismic station installed on Gaua show that many explosions occurred on Gaua volcano. Volcanic gas flux measurements on October 3rd show that 3000 tons of sulfuric dioxide is released from this volcano each day, this means that a significant quantity of magma is degassing from gaua volcano. The lake letas, localised close to the Mont Garet volcano, is one of the biggest crater lake of South Pacific, its volume reachs 800 million cubic meters which is drained out through the river of the Waterfall.

With this information, the Alert level of this volcano is now raised to
Level 2 on the Vanuatu Volcano Alert Level (VVAL). This means that this
volcano is going through a minor eruption. It is not recommended to
approach the volcano. The danger remains in the red zone area on the hazard
map including all the river outlets in Gaua, especially the river of
waterfall. With the related alert level, a level of response from the
community is required. Geohazards is doing its best with the limited
resources available to continue monitoring this volcano.

No real indication in any of this about ideas of the extent of the eruption - sounds like it is just small explosive events so far - and a lot of sulfur dioxide. Another volcano to keep an eye on to see if the eruption escalates or that this is merely a transient event at Gaua.
