Surface displacements in Japan before the 11 March 2011 M9. 0 Tohoku-Oki earthquake

Daily resolution data retrieved from the 1243 ground-based Global Positioning System
(GPS) stations in Japan are utilized to expose surface displacements before the destructive
M9 Tohoku-Oki earthquake (March 11, 2011). Variations in the residual GPS data, in which
effects of the long-term plate movements, short-term noise and frequency-dependent
variations have been removed through a band-pass filter via the Hilbert–Huang transform,
are compared with parameters of the focal mechanism associated with the Tohoku-Oki …
