Abstract:
The nature of long-term vertical crustal movements observed in the southern Primorye is oscillatory and related with the subduction zone processes. Vertical postseismic displacement velocities ranging from 7 to 14 mm/yr have recognized up to January 2014 at a set of GPS stations located ~1000 km westward away from the Tohoku earthquake epicenter. They have still been continuing. Vertical coseismic crustal offsets were not detected in the far-field zone. Change of the sign of the earth’s surface tilt in the far field zone might be used as a long-term precursor of catastrophic earthquakes in the subduction zone. For more reliable and detailed understanding of the relationship between geodynamic processes in the far-field and subduction zone it is extremely important to perform more dense continuous GPS observation in the region under study.
