Effectiveness of Alpha and Itanium microprocessors for the numerical modeling of vibroseismic monitoring of magmatic volcanic chambers

The paper considers theory, methods and experiments aimed at creation of a monitoring system of active volcanos with the use of powerful vibroseismic sources. We propose a concept of creation of a system for studying the geometry of magma chambers, deep faults in the neighborhood of volcanos, dynamics of eruption...

Increasing of sensitivity of active vibroseismic monitoring method with allowance for wave field nonlinearity

Nonlinear wave processes of radiation and propagation of elastic oscillations in complex subsurface geometries are analyzed in terms of their role in improving the quality of seismic monitoring of geodynamic processes. The efficiency of this approach is illustrated by measuring parameters of seismic waves and analyzing their temporal dynamics with...

Detecting possible impact craters on the Earth's surface using the DEM data processing

A new attempt to the detection of the impact craters and other morphologic structures on the Earth's surface was made using high-tech computational methods. For detection and allocation of such structures, the fast two-dimensional wavelet transformation and the fast nonlinear multiparameter regression analysis for the digital elevation (DEM) data subsets...

Research into periodic signal processing by the median filters

We discuss a specific nature of the phase-synchronized-weighted (Synphase-Weighted) Median Filters when processing frequency-modulated (possibly, swip) signals recorded at a discrete time. It is shown that the response of the Synphase-Weighted Median Filters weaker depends on the filter length than the response of conventional median filters. The conclusions obtained are...
