The concept that there may be a causal relationship between solid-earth tide stresses and earthquakes and volcanic eruptions has been aired for some time, but without sufficient example in the field. Recently, S.R. McNutt and R.J. Beavan have been able to demonstrate such a correlation at the Pavlof volcano located along the Alaska peninsula. The three criteria required to evaluate such a correlation are the following. A statistical number of events, a constant accumulated strain, and a limited focal region are the criteria noted by A. Ryal et al. (Bull. Seismol. Soc. Amer, 66, 1821–1846, 1976), and McNutt and Bevan think the first and last of these are met at Pavlof.
