DETERMINATION OF THE DISTANCE FROM THE EARTHQUAKE EPICENTER TO THE SEISMIC STATION
Keywords:
engineering seismometric station; seismometer; seismogram; distance; earthquake epicenter; longitudinal seismic wave; transverse seismic wave; velocity of the longitudinal seismic wave.Abstract
According to the data of the Republican Center for Seismic Prognostic Monitoring of the Ministry of Emergency Situations on the magnitude at the epicenter of the earthquake, the depth of the earthquake, the distance from the epicenter to the engineering seismometric observation station and the difference in the arrival time of longitudinal P and transverse S seismic waves determined by the seismograms of this station, it is possible to calculate the velocity of the longitudinal P seismic wave. Knowing the velocity of the longitudinal P seismic wave and the time difference between the front of the longitudinal P and transverse S waves, determined by seismograms, it is possible to calculate the distance from the epicenter of the earthquake to the location of the seismometric station.
