Haiti earthquake ground motion estimated at 10 cm/s

 Or less.  Looks like the main 'hammer' of the earthquake was directed away from Haiti.  

A building collapsed that had no steel in the concrete.  The building next door is fine.


A rubble house collapsed and there is a nice house beside it.  That house was built on a thick concrete slab with steel.  A house built with steel and concrete should survive 20-30 cm/s.

Haiti better start building right because the next earthquake, most likely in 10 years, will produce 20-30 cm/s.

ps.  an instrument at the US embassy measures it at 5 cm/s.
