Zusammenfassung |
We obtained the time-lapse cumulative slip before and after
the 29 November 1999, Xiuyan, Liaoning, China, Ms = 5.4 earthquake by
using "repeating events" defined by waveform cross-correlation. We used
the seismic waveform data from the Liaoning Regional Seismograph Network
from June 1999 to December 2006. Two "multiplets" located near the
seismogenic fault of the 1999 Xiuyan earthquake and the 4 February 1975,
Haicheng Ms = 7.3 earthquake, respectively, were investigated. For the
"multiplet" that occurred before and after the 1999 Xiuyan earthquake, apparent
pre-shock accelerating-like slip behavior, clear immediate-post-seismic
change, and relaxation-like post-seismic change can be observed. As a
comparison, for the "multiplet" near the 1975 Haicheng earthquake which
occurred a quarter century ago, the cumulative slip appears linear with a
much smaller slip rate. |
