The largest of the dacite domes formed the previous summit, and off its northern flank sat the smaller Goat Rocks dome Both were destroyed in the 1980 eruption A few weeks ago, scientists have measured that the lava dome is rising about 5 meters (164 feet) a day, probably preparing the next big blast!.
