no surface rupture onshore, fault slip beneath offshore

Francisco "Paco" Gomez, prof at U. Missouri, just gave me an OK to mention that he just did an interferogram (comparing before and after satellite (images? radar?)) that shows the fault slip was farher west and partly offshore. He and his student also have not seen evidence from 40 cm resolution post-quake satellite for onshore surface rupture. We also heard this from another geologist expert on Haiti (who is there now).

I mapped the offshore fault that I posted on seismic profile as "unnamed fault".

I had posted a couple of days after the quake that the part of the GeoEye post quake satellite that was linked as a Google layer showed no sign of surface rupture in the east, south of Port au Prince. Must be because the fault did not break there, even at depth.
