The Oriente cluster is named for the Oriente Fault along the southern
coast of Cuba. It is larger in area than usual for GCCEL (~500 km
across) in order to include enough station coverage for stable location
calibration. The cluster includes the 7.7 Mw earthquake on January 28,
2020 and three M6 events: on May 25, 1992 (6.8 Mw), February 4, 2007
(6.2 Mw) and November 10, 2024 (6.8 Mw). In order to stabilize the
relocation many small events were retained. About 1/3 of the earthquakes
were recorded to teleseismic distances. All events have depth constraint
from near-source and local distance readings, as well as teleseismic
depth phases for some of the larger events.
