Magnitude 6.8 Earthquake Strikes Offshore Cuba, Causing Moderate Shaking and Minor Disruptions

A significant earthquake struck offshore of eastern Cuba on Sunday, November 10, 2024. According to the United States Geological Survey (USGS), the earthquake had a magnitude of 6.8 and occurred at 11:49 local time, approximately 39 kilometers south of Bartolomé Masó in the Granma province[3].

The quake was felt widely in the region, with moderate-to-strong shaking reported in parts of eastern Cuba near the epicenter. Cities such as Bartolomé Masó, Yara, Campechuela, Manzanillo, Contramaestre, and Santiago de Cuba experienced varying degrees of shaking, ranging from light to moderate.

The earthquake occurred at a depth of about 23.5 kilometers, which is relatively shallow and can result in stronger ground shaking. Despite the significant magnitude, there have been no immediate reports of major damage or casualties. However, authorities are expected to conduct comprehensive damage assessments, particularly in remote areas, which may take several hours[1].

A small possibility of tsunami waves on nearby coasts was noted, although no tsunami advisories have been issued. Aftershocks are likely in the coming days, and residents are advised to be cautious, especially when operating in or near multistory buildings until their structural integrity is confirmed by authorities[1].

Minor disruptions to transportation infrastructure and utility services are possible, particularly in areas close to the epicenter. Officials may temporarily shut down transportation infrastructure to check for damage, and travelers are advised to plan for potential delays and check road conditions before driving in hilly areas due to the risk of landslides[1]).
