We have another earthquake along the Panama fracture zone (PFZ) plate boundary. There are numerous sub-parallel transform (strike-slip) faults in this region. The most recent earthquake is a M = 5.7 and is plotted as the most southerly orange dot in this map. Orange denotes a hypocentral depth of 0-33 km. There was a swarm further to the north in May of 2014.
Here is a zoomed in view (“larger” scale than the above maps). One may observe the north-south oriented ridges in the sea floor. These are the various faults associated with this plate boundary. There appear to be 4 or 5 major faults.
Today’s M = 5.7 earthquake is just to the south west of the M = 5.1 from 1/31/15 plotted on this map. I discussed the PFZ on an earlier post.
Here is the moment tensor from this M = 5.7 earthquake. It matches the earlier quakes and, with the knowledge of the faults in the region (the PFZ), I interpret this earthquake to be right lateral strike slip.
