Comparison on co-seismic responses of water tube tiltmeter and vertical pendulum tiltmeter at Hegang Seismic Station
摘要
Abstract
Analyzing co-seismic responses recorded by water tube tiltmeter and vertical pendulum tiltmeter in Heilongjiang Province, we consider that the co-seismic responses of water tube tiltmeter and vertical pendulum tiltmeter recorded are different for the earthquakes with different epicentral distance. Numerical stability of the water tube tiltmeter is better than that of vertical pendulum tiltmeter, but responsive sensitivity of vertical pendulum tiltmeter is better than that of water tube tiltmeter. Co-seismic responses of both instruments recorded are accociated with magnitude, focal depth, epicentral distance.关键词
