Just laying this out there... I check daily for seismic activity in the Caribbean Sea and there are daily "earthquakes" in the vicinity of Puerto Rico. Its everyday 4-5 earthquakes reported in the area. Sometimes up to a dozen. When I zoom out on the map, Alaska and Tonga/Fiji are much the same many days.
