Summary

The Earth's crust and mantle structure in the region Crimea are investigated on the surface waves observations. For this investigation the long-period seismographs have been installed for the triangle of the seismic stations Simferopol, Alushta, Theodosiya. The phase velocities dispersion has been determined on the base of surface waves for the 8 earthquakes. The observed dispersion curves agree with the theoretical ones for the Earth's model with the crust's thickness of 36–40 km and with (in the mantle) the low velocity layer (V s =4.3 km/sec at the depth of about 120 km).

Резюме

Исследовалосъ строение земной коры и мантии Земли в рай оне Крыма по наблюдениям поверхностных волн землетрясений. Для этих исследовани й были установлены длиннопериодные сейсмографы в треугольнике сейсмичес ких станций Симферополь, Алушта, Феодосия. Ъыли определены дисперсионные кривые фазовых скоростей волн Релея для 8 землетрясений. Наблюденные дисперсионные кривые хорош о согласуются с теоретическими для модели Земли с земной корой мощностью 36–40 км. И слоем пониженной скорости в мантии Земли (V s=4.3 км/сек) на глубине порлдка 120 км.
