As a mean to assess the risk dam structures are exposed during earthquakes, we employ an abstract mathematical, three dimensional, elasto-acoustic coupled wave-propagation model taking into account (i) structure itself, embedded (ii) its surrounding topography, (iii) different material soil layers, (iv) seismic source as well (v) reservoir lake filled with water treated acoustic medium. case st...

The paper studied the vibrations of buildings on sliding foundation with dry friction under action real earthquakes at intensity 8 and 9 MSK-64 scale. It was developed a unique algorithm for calculating displacements, velocities, accelerations, shear forces resulting from simultaneous horizontal vertical components seismogram record. four-story nine-story set three earthquake records. shown tha...

in exploration seismology, estimation of elastic parameters of rocks using seismic amplitudes is considered as inverse problems. nowadays, model-based and more generally optimization-based algorithms are of the most common methods of seismic inversion. these algorithms which are known as deterministic methods, are suffering from two main problems; first, vertical resolution of outputs is very l...

We have built user environments that simplify and provide interactive access to data, models, and compute resources as well as integrate various distributed computational services to study earthquake waveforms utilizing 3D models and compute resources within the Geosciences Network (GEONgrid) and national computational grids, such as TeraGrid. These data and computing services are implemented u...

The Moho discontinuity is one of the fundamental boundaries on Earth, separating crust from upper mantle. Arrival times seismic reflection and refraction data are used to estimate depth Moho, but nature remains illusive. We present a synthetic seismogram modelling study for suite possible velocity models oceanic lower transition zone (MTZ). For modelling, we have 45-km long multichannel streame...
