Some of the IGS stations placed in Japan are providing data after the magnitude 9.0 earthquake that hit Japan on March 11th, 2011. We have processed data from those stations with magicGNSS, to evaluate the site displacements due to the earthquake and its aftershocks. They are shown in the following graphic:

The pre- and post-earthquake coordinates have been computed with static PPP (GPS only, as most of the sites do not provide GLONASS data) using 1 day of data (March 10th and 15th, 2011, respectively).

Note that due to the aftershocks, the coordinates on March 15th may not be considered truly static, yet the results are considered very illustrative of the magnitude of the event.

The location of the sites is shown in the map. Click on the icons to see the corresponding displacements. We also include the location of the epicenter.
