March of the earthquakes - M7.2 Haiti


This is a classic 'marching' earthquake along a strike-slip fault.  History has them marching all the way to Jamaica.  As well, the upper fault gets activated.

The only place to build a town is on deep sediment basins.  That's why the effects are so strong.

ps.  This is a thrusting strike-slip.  That's why there is that long ridge, being the hanging wall.

pps.  almost 2 cm/s in Jamaica, 1 cm/s in Dom. rep.  probably on rock.
