Regional variations of the intrinsic shear wave quality factor Qµ in both the upper crust and
upper mantle of continents are large, with values in old, stable cratons exceeding those in …

Surficial mass movements, such as debris avalanches, rock falls, lahars, pyroclastic flows,
and outburst floods, are a dominant hazard at many volcanoes worldwide. Understanding …

The structure of the earth has been extensively studied using seismic waves generated by
natural earthquakes and man-made sources. In classical seismology, the earth is …

Seismic measurements take many forms, and appear to have a universal role in the Earth
Sciences. They are the means for most easily and economically interpreting what lies …

We present a new method to estimate stable seismic source parameters, such as energy,
moment, and Orowan stress drop, using regional coda envelopes from as few as one …

ModelHVSR is a user-friendly collection of Matlab® routines performing a number of tasks
related to analysis of microtremor data. Its distinguishing features include: The program may …

Forecasting the location of an eruption is of primary importance for risk management in
volcanic regions. Locating the underground structural changes associated with a potential …

We present a method for locating the source of seismic events on Piton de la Fournaise. The
method is based on seismic amplitudes corrected for station site effects using coda site …

Two seismic wave attenuation factors, scattering attenuation (Qs− 1) and intrinsic absorption
(Qi− 1), can be determined from estimates of two parameters, the reciprocal of extinction …

OpenHVSR is a computer program developed in the Matlab environment, designed for the
simultaneous modeling and inversion of large Horizontal-to-Vertical Spectral Ratio (HVSR …
