There were 10 seismometric stations （ including telemetric stations ） and 13 precursor monitoring stations with 17 observation items within the distance of 300 km from the epicenters. There were 18 medium term, short term and imminent anomalies. 7 of them were anomalies in seismic activity and 11 items were precursory anomalies. The proportion of precursory anomalies within the distance of 200 km from the epicenters was 73%.
