Introduction
Deformation at active volcanoes spans a wide range of frequencies, from permanent changes up to cycles of 100s of Hz. Scattering and anelasticity attenuate the high-frequency signals rapidly, making their detection difficult. The dominant range of frequencies observed with seismological methods, between about 0.5 and 5 Hz, has been well recorded for many decades, beginning with analog recordings. Studies of discrete events and longer-duration tremor in this so-called long-period (LP) band have led to significant advances in understanding of volcanological processes, but studies of events with lower frequencies have only been possible since the use of instruments that can record them has become widespread.
Very-long-period (VLP) seismicity with frequencies below the LP band has been observed at nearly every type of active volcano, including those with activity limited to hydrothermal systems. As with LP seismicity,...
