抄録

Microtremors with periods of 1 to 10 seconds were observed at 8 points in and around Weihe Basin, Shaanxi Province and in Shanghai City, China, from Marcn 20 to March 26, 1990. A middle-period seismograph with a digital recorder was employed as a mobile observation system. Spectral analysis was made on the observed microtremors.The predominant peoriod was found to be about 5 seconds at almost all stations. Amplitudes of the micro-tremors were 10 or more times larger at points where sediments are supposed to be thick than those observed on basement rocks.The amplitude of the microtremors with a period of about 5 seconds at Quanling, that is located around 1000 km apart from the sea, showed almost the same value as that obtained at Sheshan located about 60 km from the sea. These facts are important to study the origin of the microtremors and their propagation mechanism.
