Guadeloupe is, with Martinique, classified in seismicity zone III (decree n° 91-461 of May 14, 1991) which is the highest level of seismic hazard for the French territory. The previous earthquake of this importance in Guadeloupe occurred on November 21, 2004. With a magnitude of 6.3, the earthquake in Les Saintes was the most important one to have occurred in France since the Provence earthquake of 11 June 1909. Its epicenter was located south of Guadeloupe, between the archipelago of Saintes and Dominica. The macro-seismic intensity reached VIII in the Saintes archipelago. It was the strongest macro-seismic intensity observed in France since the Arette earthquake of August 13, 1967 in the Pyrenees. The Saintes earthquake mobilized many people, scientific research laboratories and technical centers. It had caused a lot of damage.
