Long-term GPS Station Velocities
These vectors (see 30 mm/yr scale at top left) show the long-term average tectonic motion captured by GPS stations in the region.
Nearest GPS/GNSS Stations
Stations within the radius of predicted 1 cm displacement. The Chignik-Shumagin network is an NSF-funded PI network. Contributed daily stations include Alaska Volcano Observatory stations, Alaska Earthquake Center stations, and others.
