Evolution of magnetotelluric,total magnetic field,and VLF field parameters in Central Italy:relations to local seismic activity
Magnetotelluroc tectonomagnetism VLF waves
2015/9/28
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and rob...
Non-parametric analysis of a single seismometric recording to obtain building dynamic parameters
damping fundamental mode singledegree-of-freedom ambient vibration
2015/9/2
We propose a simple time-domain, non-parametric method to estimate the damping at the fundamental frequency of a building. The method aims at obtaining quick-and-dirty data on large sets of buildings,...
Equivalent Medium Parameters for Numerical Modeling in Media with Near-Surface Low Velocities
Equivalent Medium Parameters for Numerical Modeling Media with Near-Surface Low Velocities
2014/4/10
We have developed a methodology to discretize an isotropic velocity model with low velocities near the free surface for full waveform numerical modeling. The method modifies the near-surface minimum v...
