A lava dome began erupting just from the center of the summit crater, Dietrich said. Scientific core samples indicate eruptions about 4,000 and 4,300 years ago, with additional eruptions before that. In this case, it would have taken the audible sound waves about seven hours after the explosion to be heard in Alaska, according to Fee.

Tectonic Setting of the Alaska Peninsula . So yeah, this is pretty unique, he said. These occur without warning and typically generate small clouds of volcanic ash that are a hazard in the immediate vicinity of the volcano, though more significant ash emissions are possible.
