The Lesson of Eyjafjallajokull
Weeks ago the eruption of Eyjafjallajokull (the volcano in Iceland everybody was butchering the name of in the televised news) was international news. This slumbering volcano stirred and belched molten earth and ash into the skies. From there, winds and the jet stream spread this dangerous gaseous soup all over Europe, affecting weather patterns and international travel for days. It was almost impossible to get a flight in or out of Northern Europe at the time. Industry experts project the lost revenues caused by the initial eruption to be $1.7 billion or more. Some speculate it might have been bad enough to literally drive some European air carriers into bankruptcy.
But the eruption is not over. In recent days Ireland and Scotland have been struggling with another ash cloud which may soon, once again, influence larger segments of Europe. While some people might consider this a sign that “the Mayans were right” or as some kind of evidence of a foretold doomsday scenario unfolding before our eyes, I am confident in saying that is simply not true. What we are witnessing is a normal and natural geological process. The process by which the Earth’s mantle is replaced is well documented and easy to understand.
At fault lines and trenches, the crust of the Earth winds up being pushed down into the core. The deeper this material goes the more heat and pressure it is subjected to. Eventually this material is reduced into magma. Magma flows all around and through the planet in various concentrations and densities. Eventually, a local concentration of magma will reach a critical level and trigger a volcanic eruption. This is not a strange or mystical process. It does however seem to be basic geology that is somehow not learned during the course of most people’s elementary sciences.
There are volcanoes all over the world, both dormant and active. Unfortunately, a lack of funding has led to a woeful inability to monitor, track, and even understand the complicated systems involved in volcanic eruptions. It has been deemed more important to fund weapons systems than developing early warning capabilities that might, at the least, help us prepare for and work around volcanic eruptions. Do not think that such an investment would be fool hardy. Eyjafjallajokull is just a “normal” volcano and the impact it has had on Europe’s people and businesses is impossible to deny. The threat that ought to concern humanity lies in “super volcanoes.”
There are at present at least six known super volcanoes, three of them in North America alone. These volcanoes are so massive that if one were to erupt they would belch more than 240 cubic miles of ash, dirt, and magma into the sky. These are eruptions that are large enough to change weather patterns, block out the sun, and potentially even trigger new ice ages. There is currently no “real” way to “prepare” for the eruption of a super volcano. The best you can do is hope that they manage to release their pressure in smaller and less destructive ways (like geysers) than a full scale eruption.
The fact that we are so woefully unprepared to understand and predict, or possibly even prevent, catastrophic eruptions has nothing to do with it being “impossible.” It is instead the fault of people in positions of authority refusing to deal with such situations because it is considered a political liability with little to no reward. I cannot help but wonder what the people of New Orleans think about the decades of negligence on the part of local, state, and Federal officials to deal with the problem of their inadequate levies, preferring instead to “hope nothing bad would happen.”
