I just keep thinking to myself..what goes up, must come down, right? How does this apply? When subduction events occur, large volumes of solid rock
are thrust down deeper into the earth. Eventually the rock mass liquifies and is again extruded to the surface (under the water in this case).
Eventually the rock cools, and the process repeats itself in time. So in this case, it's 'what goes in, must come out.'
So how much rock was subducted by the continuing procession of 5.0+ earthquakes in SE Asia? That's the question...
What other explantions apply to the growing, rising magma column under the US? The West coast is presumably the destination, as there must be
extensive channels and chambers beneath the Rainier system. SE Asia has what is probably one of the largest, if not the largest system of subteranean
magma chambers. I shudder to think that they may actually have filled up during the series of events we all witnessed.
If they're full..then that's a tremendous amount of material, just itching to come back up. Unfortunately we don't have any way of measuring the
content or even the relative fullness of the magma chambers. They could be filled with sluggish, gas-poor magma, or they could be full with explosive
gas-rich magma..hell, they could be almost completely empty, and all my concern would be for nothing. Who knows?
