A strong swarm of earthquakes hit the Reykjanes Ridge region of the Central Mid-Atlantic today. A series of moderate to moderately strong earthquakes also occurred in the region in the Greenland Sea and in association with a possible sub-glacial eruption of Katla. The antipodal region was also active with moderate earthquakes in the region of New Zealand.

The Reykjanes Ridge was at solar noon when a strong geomagnetic storm hit with Kp up to 8 and AP 20 for the day. This is the latitude and longitude which is most likely to be affected by sudden commencement geomagnetic storms such as this. At the same time two C-class solar flares occurred and probably added to the triggering effects of the geomagnetic storm. The area was also under stress from the Post Tropical cyclone Ophelia which passed near the epicenters of these events late yesterday and early today. The combination of these triggering stresses probably forced these earthquakes at this time. This had been anticipated in this summary yesterday where we noted in this regard:


"A possible geomagnetic storm coming today or tomorrow may tip the scale back towards an active seismicity pattern globally. The previous such storm did not have the effect of triggering large earthquakes but a number of moderate earthquakes did occur in unusual and expected localities and these indicated a pattern of (unexpectedly) moderate triggering from that storm. A large earthquake is considered likely with about a 50% probability in the next two days if this storm should occur. Such an event is, as always, most likely along the geomagnetic equator or at high latitudes." (October 4-5, 2010)

The M 5.6 in the Reykjanes Ridge swarm today was the strongest in that region in at least three years. A similar event of M 5.5-5.6 occurred on April 28, 2009 and another on September 27, 2010. The events at the end of September 2010 were likewise triggered by Hurricane Igor which passed through that area several days before that swarm. Igor had a path very similar to that taken by Hurricane Ophelia.
