METHOD FOR DETERMINING CHANGES IN EARTH RADIUS

摘要

FIELD: seismology; earthquake prediction. SUBSTANCE: method involves manufacture of specimen whose initial weight (w₀) and mass (m) are measured during seismically quiet period of the Earth. This specimen is weighed accurate to ±0,01 mcH at time intervals between measurements sufficient for relaxation of microbalance whereupon curve of specimen weight (&Dgr;w) reduction with time versus radius increment (&Dgr;R) of the Earth at given point of earth surface is constructed to determine radius of the Earth. EFFECT: provision for continuous recording of changes in earth radius. 1 dwg
