UNUSUAL EARTHQUAKE HITS SOUTH OF FRANCE
EARTHQUAKE SUMMARY FOR JULY 07, 2011
An unusually large earthquake hit in the Mediterranean Sea south of France today with M 5.3-5.6. It was felt along the southern coast of France to Sardinia and Italy and was accompanied by a loud rumbling noise for about 16 seconds. An aftershock was heard about 17 minutes later. EMSC reported felt and heard reports from France in Bastelicaccia, Casaglione, Ota, Ajaccio, Pigna, Corbara, Basia, Puget-sur-Argens, Cannes, Toulon, Le Luc, Nice, Gareoult, Marseille, France and in Sassari, Italy. Some described it as a faraway noise like a railroad or thunder. Many people said it was the first earthquake they have felt.
NEIC reported this earthquake of M 5.0 was felt in France, at Ajaccio (Corse); in Ajaccio at Corse (3) in Bastelicaccia (4), in Calacuccia (2), in Calenzana (2), in Calvi (3), in Carg (3), in Monticello (2) in Muracciole (4), in Penta- (2), in Propiano (1), in Prunelli-di-, felt in Italy, at Diano (Ligurien);, felt in Monaco, at Ville (Monaco-); in France, at Monte (Corse);, in Italy, at Pigna (Ligurien); at Sassari (Sardinien); and in Taggia at Ligurien (4).
We noted the relation of this epicenter to the Kermadec Islands earthquake prior to that event when a foreshock of M 4.1 hit the region on July 2. At that time we stated in this summary in this regard:
"Light to moderate earthquakes did hit two highly unusual epicenters however today. These events of M 4.1 in the Western Mediterranean and M 3.5 in northeastern Montana were by far the strongest in their respective epicentral areas in the past 20 years. Unusual earthquakes such as these often precede major global earthquakes." (July 3, 2011)
and
"A second highly unusual earthquake occurred in the western Mediterranean Sea west of Italy today. This earthquake of M 4.1 was not reported felt or damaging in the epicentral area but is the strongest in this general area in at least 20 years. The previous largest in this general region was an M 3.9 on March 5, 1993 but the last event within 100 km of this epicenter was an M 3.8 on April 21, 1997. this earthquake is located near the fourth nodal distance (90 degrees) from the Fox Islands earthquake last week and some triggering may have occurred in this instance." (July 3, 2011)
This earthquake occurred in the antipodal area of the major Kermadec Islands earthquake of M 7.8 which hit yesterday. Antipodal quakes are common and may be due to focusing of earthquake surface waves at the opposite point on the earth (the antipode) due to the geometry of the near-spherical earth.
