Extended Data Fig. 7: Investigating spatial extents of the pre-Tohoku-oki-earthquake wobbling using the Nevada Geodetic Laboratory’s IGS08 PPP solutions.
From: Months-long thousand-kilometre-scale wobbling before great subduction earthquakes
The map shows the locations of two groups of stations used in the investigation into spatial extent of the unstable period observed before the Tohoku-oki earthquake. The time series show the average (median) deviation from median velocity at each station of the two groups in the above map for each directional component, where the median velocity of each station is determined between 1 January 2006 and 8 March 2011.
