- 27 of them had a magnitude between 4.0 and 5.5.
- The bulletin attributes the increase to aftershocks of the August 14, 2021 earthquake (magnitude 7.2) near L'Asile and of the January 24, 2022 earthquake (magnitude 5.5) near Anse-à-Veau, both in the Nippes.

- The bulletin places the January 24 earthquake on a reverse fault north of Anse-à-Veau, which explains the repeated aftershocks in the Nippes region.
