In Haiti, Chile, Baja, Sumatra -- 4 Big Earthquakes , at http://pjdsharing.blogspot.com/2010/04/haiti-chile-baja-sumatra-4-big.html, I suggested that global warming might be the cause of the series of earthquakes afflicting various nations this year so far.
Now we have to add to that list last week's 6.9 magnitude Tibetan earthquake, and Iceland's volcano!
Six (6) huge geological events in just a few months!
Suggestion: Is it possible that just as there are "tipping points" in the environment -- where, when some of the ice starts melting, ALL of the ice starts melting, for example -- there might be "tipping points" in the geology of the Earth?
In other words, if the glacier-to-Equator flow of water from global warming reaches a rate of "X tons per minute," the braking upon Earth's rotation generated by the redistribution of tonnage to the Equator might be a tipping point where we see a constant stream of earthquakes and volcanoes, worldwide, due to the innate mechanical limits of crustal integrity and viscosity of the underlying magma.
If this is so, are we accelerating the emergence of the super-volcano in Yellowstone?
I'd be interested in what the Yellowstone tiltmeters have to tell us, these days.

Haiti, Chile, Baja, Sumatra -- 4 Big Earthquakes
The 01/12/10 earthquake in Haiti was 7.0 on the Richter scale.
The 02/27/10 earthquake in Chile was 8.8 on the similar Moment/Magnitude scale.
The 04/04/10 earthquake in Baja was 7.2 on the Richter scale.
The 04/07/10 earthquake in Sumatra was 7.7 on the Richter scale.
What's going on?
Simple proposed answer: Global warming.
As CO2 and other greenhouse gasses -- especially methane -- build-up in the atmosphere, they trap heat from sunlight, the average world temp goes up, until it reaches a "tipping point" -- the point at which, on the average, a lot of frozen water, sitting on land, begins to melt.
The ice melts, rivers dump more ice into the oceans, and global rotation generating centrifugal force throws a lot of the new water weight to the Equator.
This is the global equivalent of a figure skater, doing a pirouette, spreading her harms to slow herself down. The increase in mass at the perimeter of a rotating object causes the object's motion to compensate by slowing down.
I.e., the increase in tonnage at the Equator causes the Equator to "put on the brakes" on global spin.
This sets the slowing crust at war with the inside of the Earth, which wants to continue rotating at the previous rate.
That war generates earthquakes and volcanoes worldwide.
