1-Hz PPP displacements at GEONET stations during the 2011 Tohoku Mw9.0 earthquake

The displacements were processed over a period of more than two years with extreme care and obtained using the method of Precise Point Positioning with the PANDA software. For more technical details on the processing method, the reader is referred to Xu et al. (2019, EPS, 71:43).

In total, we successfully obtained the displacements for 1221 stations between 14:45 and 15:30 on March 11, 2011, Japan local time. To our best knowledge, this data set of displacements is probably the most complete among similar data sets for the same event.
