IGSCB 2025-01-08 UPDATE Seismic Station Yakutsk YAKT 12353M002 2000-04-24T00:00:00Z Eastern margin of Siberian platform. SEDIMENTARY NA na Permafrost This station is part of NEDA Deformation Array. NEDA operational control is provided by RDAAC Acquisition/Analysis Center (Moscow, Russia). RDAAC is also IGS Operational Center for NEDA. ******************************************* The GPS reference mark consists of 5/8-11" diameter, vertical stainless steel rod. It is glued into the concrete parapet at the southwestern corner of the roof of Seismic Station Yakutsk. This is 2-story building made from prefabricated concrete. The rod is driven into the parapet to a depth of 100 mm; its top end is 100 mm above the surface of the parapet. Vertical datum of the rod. Antenna is attached to the rod with the UNAVCO compact leveling mount. The antenna and choke ring assembly are protected with the SCIGN hemispherical dome. Mark YAKT is located 37 m to the west of IGS mark YAKZ (IERS DOMES No. 12353M001). YAKT was reoccupied several times since 1996 and showed much smaller seasonal horizontal fluctuations compared with YAKZ.
