| Abstract: | Tilt tide measurement data with digital water tube is collected at Hubei Shiyan seismostation from 2007-2010.The results of data analysis indicate that the tilt tide observation for 3 years werecontinuous and reliable,the instrument works normally and stably which has small annual zero drift and change amplitude and so it is with the low noise level.The overall quality nearly reach the international level in terms of data accuracy,continuity and applicability,though the data had been affected by the local s... |
