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.

Redoubt, oil and corporations: a tale of volcanic mitigation (or lack thereof)

January 31, 2009, 10:35 AM

The Anchorage Daily News has an excellent article today on the Drift River Oil Terminal, a depository for oil collected from the platforms in the Cook Inlet. This oil terminal stores at least 1,000,o00 barrels of oil (see article for why we're not sure) and sits, well, at the base of Redoubt (see map below from Anchorage Daily News) on the floodplain of the Drift River (~25 miles from the vent). 

Now, this oil terminal was more-or-less destroyed during the last episode of volcanism at Redoubt twenty years ago when the terminal was wiped out by floods resulting from the eruptions. Not only did this cause the retrieval of the oil left at the terminal to be an immense problem, but it shut down production in the Inlet for 10 days ... and we all know what this kind of news does to gasoline prices.

You would think that after this event, Chevron (who owns the terminal) would have thought better of building there again because, well, not only is Redoubt a volcano, but it is a fairly active one at that. I mean, its not like (for arguments sake) building an oil terminal at the base of Mt. Jefferson in the Cascades, that hasn't erupted in a thousand of years. However, from what the ADN reports, Chevron has only: (1) possibly started to move oil away from the terminal since the ramping up of seismicity and (2) added a dike that "steer waters away from the facility if another monstrous flood occurs."

I wish we knew more about what is being down about the oil terminal, because it could be a great example of when volcanic mitigation is ignored ... or alternately, if Chevron is actually doing something about it, when it is paid attention. It doesn't take a team of experts to realize that the placement of the terminal in a flood plain at the base of an active volcano might not be the best location in the Inlet. Combine that with the fact that, although a flood took out the facility in 1990, there is no guarantee that other volcanic hazards with a little more "oomph" might not be able to reach the facility, dike or not. The Drift River Oil Terminal is one of those situations where a little forethought into its placement might save Chevron and the country a lot of hassle and worry.

As for the current state of Redoubt, as of noontime (Pacific) on 1/31/09, AVO reports "Seismicity remains relatively unchanged since 3:30 PM AKST yesterday afternoon. It is still well above background." The wait continues!
