From Aug. 5th to Aug. 18th, we carried out a campaign GPS survey in Qinghai province. Main purpose of this field trip is to monitor the crustal deformation in this region, collecting data for further research on properties of active crustal faults, lithospheric rheological properties, etc.

This is a cooperative GPS survey between the University of Science and Technology of China (6 PhD and MSc students from Dr. Hu’s research team) and the Hefei University of Technology (Prof. Shuiping Li). We planned to survey more than 40 stations, but because of the surge of the COVID-19 positive cases in Qinghai, we had to cancel the rest of the itinerary. We drove two cars and successfully surveyed 21 GPS stations, including 12 stations installed by Prof. Faqi Diao at the China University of Geoscience, 3 stations from the National Bureau of Surveying and Mapping, and 6 stations newly installed by us.

We have visited station HMAH that is a continuously-operating geodesy station using the Beidou Navigation Satellite System.

We tried to setup a new survey profile across the Kunlun faults. Surveying northern part of the profile was relatively easy. For the southern part, it was difficult to find reliable bedrocks in the Yellow River Source Park of Three-River-Source National Park located. Because of the limited time, we didn’t search further for installation locations, that means, we only had half of the planned profile surveyed.

It was unfortunate that we had to cancel the rest field trip because of the COVID-19. Maybe that leaves us a good excuse to go back soon! Every one of us enjoyed the beautiful scenery in the northeastern Tibetan Plateau!
