This study analyzed data from vertical pendulum tiltmeters, water-tube tiltmeters, extensometers, borehole strainmeters, and gravimeters at three stations within 100 km of the epicenter prior to the MS6.8 Luding earthquake in Sichuan province. The results revealed that pre-earthquake observations from some instruments exceeded two times the mean square deviation, and the distance from the epicenter influenced the duration of the anomalies.
