M7.3 earthquake El Salvador

Not much news on this yet.  This is a 'baby' for such a subduction zone, which you can see, could easily rip into an M9.  The PGV on firm ground will be less than 10 cm/s, which shouldn't crack plaster.  But with the general building stock in this area, you might expect minor damage, and some landslides, if the slopes are wet.  Swamps, as usual,, will amplify by at least 10 times.

M7's are great foreshocks for an M9!
