Hi Paula and John Wakabayashi
Thank's a lot for your coments which are certainly very helpful. I fully agree with your remarks on the preservation of past ruptures since the involved active regional fault is fundamentally of strike-slip nature and recent floods might have eroded-covered event recent and small ones. also on the the dual threat of ground deformation owing to fault displacement as well as ground deformation owing to strong ground motion from the earthquake.Paleoseismological trenching has not been excaved at the site but in another location a few kilometers along strike. The interpretation I mentioned was performed there.
Can you provide me, please, the links or references to the cases of trenches opened just a couples of years after the earthquake, where the rupture was indeed recognized and it was not possible to recognized ant deformation in the trench. Every other type of references will deeply appreciated !!!!.
Cheers,
PS : Several other colleagues mailed me directly !!
