A magnitude 3.6 earthquake causes concern in Santiago de Cuba and Guantánamo.

The recent earthquake recorded in eastern Cuba, measuring 3.6 on the Richter scale, has generated curiosity and some concern among the residents of the provinces of Santiago de Cuba and Guantánamo, although fortunately, no material damage or injuries have been reported. The seismic event, which occurred at 7:18 PM (local time), is the tenth perceptible movement on the island so far this year, a figure that, while not alarming, reflects the seismic activity that characterizes this region. The National Seismological Service (Cenais) of Cuba reported that the epicenter of the earthquake was located 44 kilometers southwest of the municipality of Niceto Pérez in Guantánamo and 50 kilometers southeast of the city of Santiago de Cuba. Authorities have emphasized that so far reports of the earthquake's perception have been received from several localities in Santiago de Cuba province, highlighting the sensitivity of the population to these natural phenomena. This event adds to a notable total of 7,475 earthquakes that have occurred in Cuba during 2023, of which 14 have been perceptible. The magnitudes of these movements have ranged from -3 to 5.9 on the Richter scale, underscoring the variability of seismic activity on the island. The total number of earthquakes indicates an active geological environment that, while common, requires continuous attention. The predominance of the Oriente geological fault, which extends along the eastern part of the island, has been recognized as the main zone of seismic activity in Cuba. This geological phenomenon is part of a broader system that includes various tectonic faults affecting the region from the Dominican Republic to Mexico. Cuba's geographical location in this context makes it an area prone to seismic activity, implying that preparedness for earthquakes is essential for the safety of its inhabitants. In Cenais's report for 2023, it is highlighted that seismic activity has been particularly notable in the northern area of the province of Las Tunas. In the locality of Moa, in Holguín, three swarms of earthquakes were recorded, each with around 500 events, although mostly with magnitudes below 4. These swarms, while not perceptible to the general public, serve as a reminder of the constant tectonic activity in the region. Authorities have noted that the first two perceptible earthquakes of 2023 occurred in February, with magnitudes of 5.5, taking place 600 kilometers southwest of the Isle of Youth and 79.3 kilometers southeast of Maisí, in Guantánamo. These movements, although of higher magnitudes, were also reported without damage, suggesting that, in general, Cuban infrastructure has withstood the impacts of seismic activity in the region. The population of Santiago de Cuba and Guantánamo, accustomed to living with the threat of seismic movements, has adopted a cautious attitude toward these events. Local authorities have reiterated the importance of staying calm and being prepared for possible aftershocks or future earthquakes of greater magnitude. Education and information are key in this process, and campaigns have been carried out to raise awareness among the population about how to act in the event of an earthquake. Despite the concern that these natural phenomena may generate, it is vital to remember that most of the earthquakes recorded in Cuba are mild and do not lead to serious consequences. However, continuous monitoring and tracking of seismic activity are essential to ensure the safety of the population and minimize risks. In conclusion, the 3.6 magnitude earthquake that recently occurred in eastern Cuba serves as a reminder of the dynamic nature of the island's geology. While the scientific community continues to monitor seismic activity, the population must remain informed and prepared, making resilience in the face of these events an integral part of their daily lives. The experience accumulated over the years and the commitment to education on risk management are essential elements in facing the challenges posed by seismic activity in the region.
