Forecasting eruptions from long-quiescent volcanoes
Forecasts of eruption are uncertain. The uncertainty is amplified when volcanoes reawaken after several generations in repose, because direct...

Comparison of short-term seismic precursors and explosion parameters during the 2016–2017 Bogoslof eruption
In December 2016, the unmonitored Bogoslof volcano unexpectedly began erupting, producing at least 70 explosions over the next 8.5 months. Roughly...

A Review of the Source Characteristics and Physical Mechanisms of Very Long Period (VLP) Seismic Signals at Active Volcanoes
Very Long Period (VLP) signals with periods longer than 2 s may occur during eruptive or quiet phases at volcanoes of all types (shield and...

Spatio-temporal evolution of the magma plumbing system at Masaya Caldera, Nicaragua
Volcanic unrest in calderas can be exhibited through a variety of different mechanisms, such as changes in seismicity and ground deformation, as...
