May 2011
Our paper on the recent Mw9.0 Tohoku-oki earthquake has now been accepted in EPS. See the publications page.


Mar 2011
2011 Tohoku-oki earthquake: W-phase source inversion results are available online at http://eost.u-strasbg.fr/wphase/events/tohoku_oki_2011.


Oct 2010
I'm in Mexico City at the Geophisical institute of UNAM to install a real time implementation of the W-phase algorithm at a regional scale.


Apr 2010
The W-phase source inversion algorithm proved successful real-time operation for the recent Chilean event (Mw8.8). W-Phase solutions coming from different agencies have been presented at the 2010 SSA Annual Meeting.
