With the emergence of portable broadband seismic instrumentation, availability of digital
networks with wide dynamic range, and development of new powerful analysis techniques …

At an active volcano, long-period seismicity (with typical periods in the range 0.2–2 s)
reflects pressure fluctuations resulting from unsteady mass transport in the sub-surface …

Most of the largest volcanic activity in the world occurs in remote places such as deep
oceans or poorly monitored oceanic island arcs. Thus, our capacity of monitoring volcanoes …

Historically, most quantitative seismological analyses have been based on the assumption
that earthquakes are caused by shear faulting, for which the equivalent force system in an …

Catastrophic landslides involve the acceleration and deceleration of millions of tons of rock
and debris in response to the forces of gravity and dissipation. Their unpredictability and …

The origin of the Papua New Guinea tsunami that killed over 2100 people on 17 July 1998
has remained controversial, as dislocation sources based on the parent earthquake fail to …

Seismic data recorded in the 2–30 s band at Stromboli Volcano, Italy, are analyzed to
quantify the source mechanisms of Strombolian explosions during September 1997. To …

A fundamental goal of volcano seismology is to understand active magmatic systems, to
characterize the configuration of such systems, and to determine the extent and evolution of …

Volcanic seismology represents the main, and often the only, tool to forecast volcanic
eruptions and to monitor the eruption process. This book describes the main types of seismic …

Most studies assume that earthquakes have double‐couple (DC) source mechanisms,
corresponding to shear motion on planar faults. However, many well‐recorded earthquakes …
