Petra -

You are correct, the "blister" (its official name is the loaf) as they are calling it is now actually higher than the dome itself. I believe they said it had grown another 30 feet or more over night this morning on the news here in Seattle. There was another steam/ash release this morning and once again the earthquake activity has died down slightly. It will be interesting to see how much more it grows between now and what may ultimately be an explosive event.
