As part of the INDEPTH IV passive-source experiment from May 2007 until October 2008, 50 broadband seismographs (35 from GIPP, Germany and 15 from SEIS-UK) were deployed along two profiles across the Kunlun mountains and the Jinsha river suture in northeast Tibet. The aims of the project are to determine the crust and upper mantle structure beneath northeast Tibet, detect the sharpness of any steps in major crustal boundaries (e.g. Moho) and detect how deep major faults penetrate in order to examine the viability of the crustal flow hypothesis. The data from the 35 GIPP seismographs are archived at GEOFON at The data from the 15 SEIS-UK seismographs are archived at the IRIS-DMC at
