Methane seeping

Perhaps you've read the various reports this past week on methane being released into the atmosphere from an area of the East Siberian Sea equivalent to more than four times the area of Sweden. Permafrost in the seabed has been previously assumed to act as an effective cap for the enormous amount of methane in the area, which, if released, could lead to an abrupt global climate warming. Man made global warming is being credited with the permafrost problem, of course, with the disclaimer that they don't really know that for sure, however the authors of the accounts don't even question it. But after seeing the affects of the recent Chile earthquake which moved one of its cities 10 ft. and recalling that it wasn't as strong as the Alaskan earthquake of 1964, I'm wondering why the disturbing of the permafrost in the sea has to be attributed to human industry and not to the affects of the most powerful earthquake in recorded history? We visited Alaska in 2001 and you can still see the affects it had on the permafrost and forests.

They can blame human activity all they want, but if this is as serious as as sounds, things will heat up very fast, and we can't do diddly squat about it.

Methane releases from Arctic shelf may be much larger and faster than anticipated (3/9/2010)

Update: "The massive magnitude 8.8 earthquake that struck the west coast of Chile last month moved the entire city of Concepcion at least 10 feet to the west, and shifted other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil. These preliminary measurements, produced from data gathered by researchers from four universities and several agencies, including geophysicists on the ground in Chile, paint a much clearer picture of the power behind this temblor, believed to be the fifth-most-powerful since instruments have been available to measure seismic shifts."

If an earthquake can do that to a city, imagine what it can do to permafrost!
