Abstract

Volcanic earthquake swarms at Pavlof Volcano, Alaska, correlate significantly with solid earth tidal stress rate for periods just before and just after explosive eruptions. The correlation changes sign systematically during the course of the 1974 minor eruption sequence; pre-eruptive earthquake swarms occur during increasing tidal compression, while post-eruptive swarms occur during increasing tidal extension.
