Earthquake surface rupture is the result of transformation from crustal elastic strain accumulation to permanent tectonic deformation. The surface rupture zone produced by the 2001 Kunlunshan earth- quake (Mw7.8) on the Kusaihu segment of the Kunlun fault extends over 426 km. It consists of three relatively independent surface rupture sections: the western strike-slip section, the middle transten- sional section and the eastern strike-slip section. Hence this implies that the Kunlunshan earthquake is composed of three earthquake rupturing events, i.e. the Mw=6.8, Mw=6.2 and Mw≤7.8 events, respec- tively. The Mw≤7.8 earthquake, along the eastern section, is the main shock of the Kunlunshan earth- quake, further decomposed into four rupturing subevents. Field measurements indicate that the width of a single surface break on different sections ranges from several meters to 15 m, with a maximum value of less than 30 m. The width of the surface rupture zone that consists of en echelon breaks de- pends on its geometric structures, especially the stepover width of the secondary surface rupture zones in en echelon, displaying a basic feature of deformation localization. Consistency between the Quaternary geologic slip rate, the GPS-monitored strain rate and the localization of the surface rup- tures of the 2001 Kunlunshan earthquake may indicate that the tectonic deformation between the Ba- yan Har block and Qilian-Qaidam block in the northern Tibetan Plateau is characterized by strike-slip faulting along the limited width of the Kunlun fault, while the blocks themselves on both sides of the Kunlun fault are characterized by block motion. The localization of earthquake surface rupture zone is of great significance to determine the width of the fault-surface-rupture hazard zone, along which direct destruction will be caused by co-seismic surface rupturing along a strike-slip fault, that should be considered before the major engineering project, residental buildings and life

This is a multicenter benchmarking study on liver transplantation(LT)for perihilar cholangiocarcinoma(PHC)after neoadjuvant chemoradiotherapy(1).The study comprises of 134 patients from 2014 to 2018 among whom the majority had underlying primary sclerosing cholangitis(PSC).Dropout rate was available from 4 out of 17 centers and was 28%,primarily for oncological reasons(tumor progression and lymph node invasion).All patients followed neo-adjuvant chemoradiotherapy according to the Mayo(88%)or Mayo-like *** grafts originated from brain-dead donors in 61.3%of cases and from living donors in 29.7%of cases.
