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.
