摘要
Comparative analyzing co-seismic response of water-tube and horizontal pendulum tiltmeters at Yunlong Seismic Station in Yunnan,the results show that both of the water-tube tiltmeter and horizontal pendulum tiltmeter have different degree of co-seismic response to distant,near and local shocks.Usually,the response amplitude recorded by horizontal pendulum tiltmeter is larger than that of water-tube tiltmeter for the same earthquake.And for the same observation system,the response amplitude is proportion to the magnitude of earthquake,and the oscillation time is relevant to epicentral distance and magnitude.
