Volcano Futures

Now that the volcanic ash cloud is easing off from Europe and airports are re-opening, it's time to look ahead a bit. The first question is, will the Eyjafjallajökull (.OGG) volcano's ash cloud visit the US? According to Discovery News, the answer is: not likely. This article also provides good current answers, as best scientists know, to other questions such as "How long will this volcano keep erupting?" (could be months), and "Will the ash cloud cause cooling in Europe?" (nope). New Scientist looks at the question of whether planes can fly safely through volcanic ash clouds — and concludes there's a lot we don't know. "Ever since a Boeing 747 temporarily lost all four engines in an ash cloud in 1982, the International Civil Aviation Organization has stipulated that skies must be closed as soon as ash concentration rises above zero. The ICAO's International Airways Volcano Watch uses weather forecasting to predict ash cloud movements, and if any projections intersect a flight path, the route is closed. But although it is certain that volcanic ash like that hanging over northern Europe can melt inside a jet engine and block airflow, nobody has the least idea about just how much is too much. After a week of losing millions every day, airlines are starting to ask why we can't do better."

  1. Volcanoes are Earth's pimples by BadAnalogyGuy · · Score: 4, Insightful

    You geeks should probably have a clear concept of how volcanoes work. It's like a gigantic pool of molten sebum seething and swelling just under the surface of the earth. When this sebum reaches a vent or finds a weakness in the skin, it erupts pus and bacteria all over. In some areas, these "pimples" are very common. Many can be found on or near the so-called Ring of Fire.

    After erupting, the area is still tender and prone to subsequent eruption, but a treatment of peroxide and salicylic acid can help clear it up and prevent infection.

    As I was saying, just because one volcano calms down on one side of the Earth, another volcano may be getting closer to eruption on the other side (Yellowstone). If you think pimples on your face are bad, wait until you get one on your ass.

    Had they permitted a plane to fly, and it crashed, the outcry of permitting a plane to fly when we knew about the risks posed by volcanic ash...

    But this wasn't even volcanic ash, it was volcanic glass, the effect would be sandblasting the engine while in operation. The safe option was to keep planes on the ground.

    Fly or stay grounded - either way, whiners will whine.

  3. Why can't we do better? Are you fucking kidding? by Chas · · Score: 4, Insightful

    After a week of losing millions every day, airlines are starting to ask why we can't do better.

    Tell you what. Let all the bean counters volunteer to get into a jet and fly back and forth through an ash plume until the engines fail and the jet crashes, killing everyone.

    THEN ask that stupid fucking question again.

    The reason nobody can say is there's no metrics for uptake by a jet and no guarantee that the ash plume is going to be consistent with whatever testbed is set up.

    Honestly, losing millions a day? Do they want to invest a couple billion a year (if not a month) into testing every plausible (and some implausible) ash-to-air-to-engine-intake ratio for every commercial jetliner extant?

    With various air carriers already cutting finances close to the bone, I don't think they really have the money to spend on this kind of research or on remediation methods and practices for overhauling engines on planes after scenarios like this.

    At $10M per and a significant fraction of that just to do a teardown and evaluation I'm not sure that anyone wants to fund that kind of research. Perhaps the government could do it with surplus engines from retired F-16's or something.

    $10M is nothing when they're losing something like $200M per day.

    Well, perhaps it's time that corporate shipping planners got a reminder that if you do just in time shipping & supply with zero buffer, eventually the supply chain will blink or shut down for a week due to uncontrollable acts of nature and you'll be boned.

    I understand that this doesn't apply to live-shipment items like tulips or medical radioisotopes, but I find it disturbing how much of our economy has been reorganized into something resembling a program that will crash if there's so much as a cache miss in the name of efficiency. Then again, I'm very conservative when it comes to matters of economic robustness - the economy of Vinge's Namqem and the food supply for Asimov's Trantor are my idea of worst-case "how in the name of Christ could anyone anywhere have ever thought this was a good idea?!" scenarios.
