- Abstract:
- Through investigating and detecting the activity of faults in the east margin of the Taoyuan basin,some structure phenomena with seismic geological significance have been discovered. The analyze results show that the Jinsha River Valley faults on the eastern margin of the Taoyuan basin are composed of a group of listric normal faults with stick slip mainly since late-Pleistocene,and its vertical movement rate was 0.6 mm/a since about 45 ka。The NW—NWW strike faults in the basin are a group of normal faults conjugate with the Jinsha River Valley fault,and an earthquake about M7 occurred between 22 ka and 44 ka. The upper limit of the magnitude of the potential earthquake source in the middle section of the Chenghai-Binchuan faults should be taken as 7.5.
