More earthquakes hit the Costa Rica-Panama border area

A series of quakes hit the southern border area between Costa Rica and Panama today, the strongest two quakes of magnitudes of around 5.5 and 5.0 at 11:45 and 11:48 local time.
Today's earthquakes in the Costa Rica - Panama border region
The epicenters were 15 km west of Puerto Armuelles (Panama) and 4 km north of Laurel in Costa Rica.
Both quakes were widely felt in up to 200 km distance. Strong shaking was felt in areas close (within 20-30 km) to the epicenter, while light to very weak shaking could be felt in a much wider area.
So far, there have been no reports of significant damage or injuries related to the earthquakes.
In addition, 8 aftershocks of magnitudes between 3.3 and 4.6 have been registered in the area, all felt as well.
The obvious concern is whether the cluster of quakes is going to continue and lead up to a larger quake or if most of the seismic tension has been released.
Costa Rica and Panama are in one of the seismically most active parts of the world, as they are just east of the tectonic boundary where the oceanic Cocos Plate is subducting (descending) underneath the Caribbean Plate, at a rate of 75 mm per year. The collision between the two constantly generates stress along the margin, which is being released in many small and sometimes larger earthquakes of magnitudes 6-7. One of the largest quakes in the area in recent decades was a magnitude 7.1 on 3 April 1983, at about 50 km to the northwest in Costa Rica.
If you were or still are in this area during the quake help others with your feedback and file a quick report here.
