Publisher Summary This chapter summarizes the new facts surrounding the spatial
variability of the b-value—the slope of the frequency-magnitude distribution (FMD) …

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 …

The frequency‐magnitude distribution of earthquakes, characterized using the b‐value, is
examined as a function of space beneath Mount St. Helens (1988–1996), and Mt. Spurr …

The recent eruption of the Cumbre Vieja Volcanic Ridge in La Palma started on September
19, 2021, after a series of seismic swarms and lasted 85 days. Seismic swarms showed a …

The seismic and deformation patterns observed on Mount Etna before and during the 1991–
1993 eruption, the third largest since the seventeenth century in terms of lava volume, are …

Seismic energy release during the precursory, eruptive and declining stages of volcanic
activities provides various information about the mechanisms of volcanic eruptions and the …

Recent seismological studies of the Cameroon Volcanic Line show that Mt. Cameroon is the
most active centre, so a permanent seismic network of six seismographs was set up in its …

Seismic activity is a common feature of volcanic eruptions. The majority of volcanic
earthquakes are small; their magnitudes do not exceed 2 or 3. At the same time, significant …

We use seismic b-values to explore physical processes during the Augustine Volcano 2005–
6 preeruptive earthquake swarm. The preeruptive earthquake swarm was divided into two …

This paper reports the present state of seismological research at Mt. Etna. A schematic
classification of the earthquakes that occur on the volcano is proposed, based on both …
