Dr. Enrique Diego Arango Arias, a Doctor of Science and the head of the National Seismological Service at the National Center for Seismological Research (CENAIS), has reported an ongoing pattern of intense seismic activity in eastern Cuba. This region has experienced a total of 808 aftershocks centered around Imías.
In a recent Facebook post, Dr. Arango Arias shared a detailed CENAIS report revealing that these aftershocks are linked to a 6.0 magnitude earthquake that struck last Tuesday in the Guantánamo province.
The report highlights that the most significant aftershock reached a magnitude of 4.6, impacting areas such as Guantánamo, Santiago de Cuba, and Holguín, underscoring the widespread nature of this seismic phenomenon in eastern Cuba.
The document further specifies that Imías alone recorded 188 tremors during the analyzed period, with magnitudes ranging from 0.8 to 4.6. Meanwhile, additional tremors were noted, albeit in smaller numbers, in regions like Santiago-Baconao, Moa-Purial, and the Windward Passage.
Moreover, seismic events were detected near Haiti in the Caribbean, with magnitudes reaching up to 4.4, indicating ongoing tectonic activity in the area.
The continued occurrence of these aftershocks has captured the attention of experts and authorities, acknowledging the potential for such seismic events to persist for days or even weeks following a major earthquake.
Understanding Seismic Activity in Eastern Cuba
What causes the frequent aftershocks in eastern Cuba?
The frequent aftershocks are primarily due to the regional tectonic activity associated with the boundary between the North American and Caribbean tectonic plates. These aftershocks are typical following a significant seismic event, like the recent 6.0 magnitude earthquake.
How do these seismic events affect the local communities?
Seismic events can cause structural damage to buildings, disrupt daily life, and pose risks to safety. Communities in affected areas often remain on high alert, and emergency services are prepared to respond as needed.
What measures are in place to monitor seismic activity in Cuba?
Cuba utilizes a network of seismological stations managed by the National Center for Seismological Research (CENAIS) to monitor and analyze seismic activity. This system helps in providing timely information and warnings to the public and authorities.
