Abstract—Seismic disturbances induced by cosmic gravitational radiation are considered. A model with a
spherically symmetric, homogeneous, isotropic Earth and a four-channel adaptive seismic lattice antenna on its
surface is used for calculations in the frequency range from 0.01–0.1 Hz. An integrated estimate of the upper
limit to the intensity of gravitational wave bursts h_up = (1.0 0.1) 10¹⁴ in terms of the dimensionless ampli-
tude of spatial variations in the metric is obtained using digital seismic data obtained over a six-month time
interval. An equivalent recalculation of h_up in terms of the spectral intensity of the gravitational wave radiation
flux density I_g gives a majorizing estimate for the upper limit I_g < 1.6 10⁸ erg/(s cm² Hz).
