GPS Velocities

The GPS velocities used in our inversion are from an updated velocity field of 151 global stations by (Steblov et al. 2003). We include data from additional campaign stations from central Sakhalin (Kogan et al., 2003) and the Kamchatka peninsula (Bürgmann et al., 2005), and from sites in northern Japan that are part of the continuous Japanese GSI network in our complete solution. These data were processed using GAMIT/GLOBK by Bob King at MIT and Misha Kogan at Columbia. Processing details can be found in (Steblov et al., 2003).

In addition to our own analysis we integrate GPS-station velocities from published work in the region that help with defining the deformation patterns for the Baikal and central Amurian regions (Calais et al., 2003). We also include selected stations from Zhang et al. (2004) that fell within or near the boundaries of the proposed Amurian microplate. These velocities were combined with our solutions by rotating them into a common reference frame. The sites selected for our inversion are shown in Figure 13.36 and Figure 13.37.
