| Abstract: | Some distinct short-term precursory anomalies were found in the level pendulum and vertical pendulum tiltmeter observations at Taian seismostation before the ML4.6 Puyang earthquake.The earthquake took place when the anomalies reached the peak and their trend is in the opposite directions of the epicenter.Because of the existence of many crossing faults between Taian station and Puyang epicentral region,the short-impending anomaly from the tiltmeter at Taian station may be the synthetic effect from the dange of large regional stress field and related faults' movement,it is a"field" anomaly. |
| Keywords: | Puyang earthquake Taian fiducial seismostation short-impending anomaly deformation observation synthetic effect |
