| Abstract: | A magnitude 8.1 earthquake occurred to the west of the Kunlun Mountains′ Pass on 14 Nov. 2001 at 17h 26m (Beijing Time). The epicentral position is 36.2°N, 90.9°E. Rather obvious short-term and imminent anomalous information had been recorded by the digital deformation observation instruments (the volumetric strainmeter, the water-tube tiltmeter and the extensometer) at the Xuzhou Seismic Station prior to the earthquake. An attempt is made in the present paper to analyse these anomalies. |
