Thrust earthquakes in outer disturbed zones

 Two thrust earthquakes this week.  First, a big one in the Philippines.  Then a smaller one north of Cuba.


The size of this one is defined by the aftershock zone.


The Cuba earthquake most likely won't have aftershocks.  These earthquakes can pack a punch close to the epicentre.  


Damage for weak construction, but a lot of buildings stood.  This is typical for 20 cm/s.  All buildings should ride through this level of ground motion.  We won't get recordings here.
