Further pilot whale strandings - eastern coast of CanadaPilot whales stranded recently at the southwest tip of Nova Scotia, about 50 miles north of Cape Sable Island near Port Maitland. http://www.cbc.ca/canada/nova-scotia/story/2009/12/24/ns-pilot-whales.html http://thechronicleherald.ca/NovaScotia/1159713.html Using the SEAQUAKE THEORY as a basis to explain this mass stranding, I did an earthquake search and found 4 suspicious earthquakes epicenter along the Reykjanes Ridge about 850 miles south of Reykjavik, Iceland and ~50 miles north of Minia Seamount. These four shallow events occurred one after the other over a period of one hour. The number of seismic stations reporting 2nd event in this swarm was 277. This leads me to believe the event was stronger than 5.3 (closer to mag. 6 Mb). I often find suspicious swarms as the likely cause of injury in deep diving whales. My guess is that the first event cause slight injury and makes the pod vulnerable to a second and third event. I believe quakes in this stretch of the ridge axis are volcanic/tectonic in nature and far more likely to generate dangerous vertical traveling pressure waves in the water column. The epicenter was located ~2,100 miles upstream from the stranding beach. This was likely a larger pod that got separated at sea by a storm--many smaller groups went ashore over a period of 7-8 days rather than one large mass stranding. This was also the same event suspected as the cause of an anomalous increase in the strandings of pelagic dolphin on Cape Cod starting on December 15. These animals also went ashore in small groups indicating that the same storm might have separated them also.
