- •
A sequence of unusual, moderate-size earthquakes occurred in a seismically quiet area offshore western Corsica.
- •
The sequence includes the largest earthquake ever instrumentally recorded in the area.
- •
A reverse faulting mechanism is consistent with shortening between the Corsica–Sardinia block and the European continent.
- •
Determination of a 6–13 km focal depth from 3 different methods for the mainshock (2011/07/07, ML 5.3).
- •
No fault is known in the epicentral area from MCS profiles.
