Influence of near-source volcano topography on the acoustic wavefield and implication for source modeling

G Lacanna, M Ripepe - Journal of Volcanology and Geothermal Research, 2013 - Elsevier
In near-source conditions (< 5km), the atmosphere is often assumed to be fully transparent
to acoustic waves and to have a small effect on the acoustic wavefield. As a consequence …

Influence of near‐surface volcanic structure on long‐period seismic signals and on moment tensor inversions: Simulated examples from Mount Etna

C Bean, I Lokmer, G O'Brien - Journal of Geophysical …, 2008 - Wiley Online Library
Long‐period (LP) seismicity on volcanoes is thought to be associated with moving fluids or
resonating fluid‐filled conduits, hence LP moment tensor (MT) source inversions might have …
