| 摘 要： | The Yutian earthquake with Ms7. 3 happened on February 12, 2014. The precursor monitoring ability is weak in that area. We found tendency anomalies and middle- and short-term anomalies from metal pendulum tilt measurements in Hotan seismic station before the earthquake. And we also compared the anomalies with that of the Ms7. 3 Yutian earthquake on March 21, 2008. The tendency anomalies measured by the metal pendulum tiltmeter appeared since 2012 as tilting eastward. While the middle- and short-term anomalies were characterized by acceleration, pause and rapid change of tilt rate in two directions. The tendency anomalies of metal pendulum tilt records are the same before the two earthquakes. They both happened in the east direction. However, there are differences in duration, characteristic and earthquake intervals for the middle- and short-term anomalies.
