Parametrization of general seismic potency and moment tensors for source inversion of seismic waveform data

S U M M A R Y We decompose a general seismic potency tensor into isotropic tensor, double-couple tensor and compensated linear vector dipole using the eigenvectors and eigenvalues of the full tensor. Two dimensionless parameters are used to quantify the size of the isotropic and compensated linear vector dipole components. The parameters have well-defined finite ranges and are suited for non-li...

Seismic moment tensor and b value variations over successive seismic cycles in laboratory stickslip experiments

The formation of fault damage due to slip under high normal stresses can rarely be monitored under in situ conditions. To advance our understanding of microfracture processes, we investigated stick-slip events on Westerly granite samples containing the following: (1) a planar saw cut fault and (2) a fault developed from a fresh fracture surface. We examined temporal changes of seismic moment te...

Facies Classifications for Seismic Inversion

Identifying facies for classification for a seismic inversion project is an important step where one balances computational effort and the quality of the results. We propose a new measure to quantify the suitability of a given facies partition based on information theory. The results depend on a user-selected cutoff, and we propose a reasonable value for this constant. We also show the analysis...

Seismic fragility assessment of RC moment resisting frame buildings designed for different editions of Iranian seismic design code

Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...

Evaluation of Cross-correlation Methods on a Massive Scale for Accurate Relocation of Seismic Events

Lamont-Doherty Earth Observatory (LDEO) at Columbia University is evaluating a method of locating seismic sources (earthquakes, explosions) based on the use of waveform cross-correlation (WCC) measurements instead of using the conventional measurements of seismic wave arrival time (phase picks). WCC measurements have been demonstrated to be 10 to 100 times more accurate, where they can be used....
