- Abstract:
- We calculated the co-seismic coulomb stress changes caused by Liyang MS5.5 earthquake in 1974 and Liyang MS6.0 earthquake in 1979 which resulted in some casualty and property losses,and compared with the distribution of aftershocks to obtain that the direction of seismogenic faults of two Liyang earthquakes should be NW.The epicenter of Liyang MS6.0 earthquake in 1979 located at the area of the static coulomb stress increasing induced by Liyang MS5.5 earthquake in 1974,and the stress values were about 0.01 bar(1 bar=0.1 MPa),which suggest that the Liyang MS5.5 earthquake in 1974 has certain positive effect to the Liyang MS6.0 earthquake in 1979,However,due to the smaller of the stress values changes,it has been unable to cause a direct trigger.
