It was analyzed the use of the telemetric complexes “Handar” intended for measurement of a sea level fluctuations and real time transfer of the gotten information to a tsunami warning service center computer in Yuzhno-Sakhalinsk where reception, visualization and the analysis of the received data are realized.
For the station located in Severo-Kurilsk situations in typical weather and with increase of long-wave processes energy during the cyclone passage were analyzed. Spectra of the obtained records were compared to spectral characteristics of the tsunamis, registered in the given point earlier. The numerical modeling of long waves propagation in investigated area was executed for interpretation of the obtained results.
The information received from Ust-Kamchatsk finds out significant reduction of tidal amplitude in contrast with earlier observation in the given point. Weak propagation of tidal waves to the location of the sea level gauge specifies its uselessness for registration of waves of a tsunami and necessity of the equipment carrying to more suitable place.
