Rome, Mar. 21 (LaPresse) – During the night the national seismic network recorded a series of seismic events in the Southern Tyrrhenian Sea, about 60 km north of the Sicilian coast, and about 15 km west of Alicudi (Aeolian Islands). This was reported by the National Institute of Geophysics and Volcanology, explaining that a total of 15 events were located. The strongest occurred at 02:46 (magnitude 4.6) with a hypocentral depth of 29 km and at 02:49 (magnitude 4.3) with a depth of 11 km. The other events recorded magnitudes between 1.7 and 3.0 and hypocentral depths between 10 and 27 km. The two strongest earthquakes occurred three minutes apart: both were felt in the archipelago and along the northern coast of Sicily, up to Palermo. "In the last 30 days," the INGV recalls, "about 30 earthquakes have been located southeast of the area affected by last night’s sequence: the strongest (ML 3.6) occurred on March 14 at 19:25 Italian time." The area near the Aeolian Islands, concludes the Institute, is a "region characterized by high seismic hazard, as evidenced by the National Seismic Hazard Map and by strong earthquakes that have occurred in the past."
