Seismic Bulletin of Haiti, October 2022
Summary: Monthly bulletin of the BME Technical Seismology Unit on the 65 earthquakes recorded in Haiti in October 2022, with magnitudes, depths and distribution by department.
Key Findings
- 65 earthquakes of magnitude 1.4 to 3.5 were recorded in Haiti in October 2022.
- 56 of them (86.1%) had a magnitude of 3 or less, and 47 (72.3%) a depth of 10 km or less.
- 38 (58.4%) occurred at sea, which the bulletin says would imply a tsunami risk if the conditions were met.
- The three departments hit by the August 14, 2021 earthquake held 34 events (52.3%): Grand'Anse 17 (16 of them at sea), Nippes 13 and Sud 4.
- September 2022 had 67 earthquakes, so October was 2 lower.
- The count in the three southern departments fell from 45 in September to 34 in October, in line with the decay law for aftershocks, while activity resumed in Ouest and Nord-Ouest.
Full Description
The bulletin reports seismic activity in Haiti from October 1 to October 31, 2022, based on local networks (Ayiti-séismes and the UTS) and regional networks (Cuba, Jamaica and the Dominican Republic). It counts 65 earthquakes of magnitude 1.4 to 3.5, breaks them down by magnitude, depth and location on land or at sea, and ranks the departments by number of events.
