Statistical analysis of Stromboli VLP tremor in the band [0.1?0.5] Hz: some consequences for vibrating structures

open access: yes, 2006
International audienceWe analyze time series of Strombolian volcanic tremor, focusing our attention on the frequency band [0.1?0.5] Hz (very long period (VLP) tremor). Although this frequency band is largely affected by noise, we evidence two significant

Slope stability monitoring from microseismic field using polarization methodology

open access: yes, 2003
International audienceNumerical simulation of seismoacoustic emission (SAE) associated with fracturing in zones of shear stress concentration shows that SAE signals are polarized along the stress direction.
