In total, 79 earthquakes of tectonic origin of maximum magnitude 4.1 on the Richter scale were identified within a radius of 450 km around Guadeloupe. With regard to Saint-Martin and Saint-Barthélemy, no earthquake was felt during this period. Between Saintes and Dominica, 21 earthquakes were recorded of maximum magnitude 3. Volcanic seismicity is also measured every month. In June, the observatory recorded 49 earthquakes under the Soufrière dome, less than 2 km deep. _EH
