Predicted Surface Deformation Data Source availability

A map of the cumulative surface deformation associated with all
Seattle/Southern Vancouver Island slow slip events from 1997 to
2007, predicted from GPS inversions and projected into ERS
line of sight. Additional slow slip events in Oregon and northern
Vancouver Island are not shown. The black outline shows the proposed
supersite area. From Matt Pritchard and Stephen Holtlkamp.
