[IGSMAIL-6369] Preliminary results on the March 11, 2011 M9.0 Earthquake in Japan on GSI's web page

[Yuki Hatanaka]

Dear colleagues,

I would like to inform you that preliminary results of the crustal
deformation associated with the M9.0 earthquake in Japan on
March 11, 2011 and the fault models obtained by the routine
solutions of GEONET is uploaded on the English web page of
Geospatial Information Authority of Japan (GSI):

http://www.gsi.go.jp/ENGLISH/index.html

Click the items in the "New topics" for detail. I just remark
that the temporal resolution of the three types of the routine
solutions are 6 hours for the quick solutions (Solution ID: Q3),
and 24 hours for the rapid (R3) and final (F3) solutions.
Some amount of post-seismic deformation is, hence, not separated
from the "co-seismic" displacement and models.

According to the Geodetic Observation Center of GSI, at least
3 GEONET stations were damaged by Tsunami and terminated the
observation.  As of March 17, we cannot retrieve data from
25 stations around the epicenter due to the failures of power
or communication line.  IGS stations operated by GSI are safe,
but coordinates of TSKB are affected by the crustal deformation
from the earthquake.

Sincerely,

Yuki Hatanaka
