Математические проблемы в геотехнологиях
The problem of an exact location of a different type of seismic sources - earthquakes, nuclear and industrial explosions is one of key in modern seismology. In the basis it the solution of an inverse problem of restoring of parameters (geographical coordinates, depth, power, time in the epicenter) source on datas of registration of seismic signals with the help of a seismic net or seismic group (set of sensor) lies. Thus the problem of reducing of inaccuracy of a location is one of basic. The main difficulty in the accurate determination of the seismic source's parameters is associated with a substantial horizontal and vertical nonhomogeneity of the Earth's crust and upper mantle. The indicated phenomenon is the reason of origin of fixed errors of a seismic source location. Other difficulty in the solution of a considered problem is stipulated by presence of signals from events of diverse nature that are of interest, for example, nuclear explosions. In this case earthquakes, industrial explosions , industrial noise are background in relation to useful event (in the given example to a nuclear explosion). It is enough to note, that the annual amount of such events registered only by a seismic net of Altai - Sayn region, is calculated in thousand. The following milestones in the solution of a problem of a seismic source location are selected: a detection, identification, measurement of times of entrances of seismic waves, definition of parameters of the epicenter and display it on a numeral georaphical map. In the given operation the problems of construction of the automized technology of the solution of listed problems are esteemed.
