| Abstract: | By analyzing the accumulated data of digital quartz horizontal pendulum tiltmeter in recent years,it is found that several hours before the occurrence of most moderate-strong and long-distance earthquakes,the observed data of the east-west component of the tiltmeter are serrated,and the solid tide curve is distorted and accompanied by obvious jitter.These studies have certain reference value for anomaly identification and earthquake prediction. |
