Good sized earthquake offshore Panama! Here is the USGS page.
This is probably an earthquake on an oblique high angle reverse fault, based on this early moment tensor. The hypocentral depth is pretty shallow too.
This looks related to the seismicity that plots along the North-South transform fault system that separates the Cocos and Nazca plates. However, it is near a triple junction and could be related to the East-West transform fault, or the subduction zone that strikes to the northwest. Very interesting.
