Energizer volcano keeps on going

Chaiten seems to have a lot of juice left. But conditions seem to be changing as it starts a new round of rumbles. It would have been nice to have this one fulled kitted out with monitors, to see it first inflate, and then slowly exhaust itself. And who knows what these latest earthquakes mean? Is the interior chamber starting to collapse in on itself? Is there any lava left or did it all fizz away like a Mentos and Diet Coke?
