Lessons Learned from the February 2023 Caribbean Earthquake

A magnitude 7.6 earthquake occurred in the Caribbean Sea on February 8, 2023, causing no injuries or significant damage. This event serves as a valuable learning opportunity for seismic response systems. Key lessons include recognizing earthquake risks outside the Pacific, understanding the complexities of tsunami warnings, and the need for improved communication among various authorities.

On February 8, a magnitude 7.6 earthquake struck the Caribbean Sea, located sufficiently far from populated areas, thus resulting in no injuries or significant damage. This outcome presents a valuable opportunity for learning and assessing our response systems, despite the event being classified as a ‘non-event’. Such earthquakes allow us to refine our preparedness for future, potentially more impactful seismic events.

This earthquake highlights an essential lesson: significant earthquakes can occur outside the Pacific region, challenging the common perception among many that the Pacific is the primary site of seismic activity. While the Indian Ocean witnessed a major earthquake over 20 years ago, areas like the Scotia Sea and Caribbean Sea also have considerable earthquake and tsunami potential, albeit with a lower frequency of occurrence compared to the Pacific.

The Scotia Sea, situated between South America and Antarctica, has produced more than 200 earthquakes of magnitude 6 and above since 1950, including a significant 8.1 magnitude quake in 2021. This area is sparsely populated, reducing immediate risk. In contrast, the Caribbean Sea is significantly larger and has a notable history of seismic activity with 21 potentially active volcanoes along its eastern margin and more than 220 recorded earthquakes of magnitude 6 or greater over the last 75 years.

The most substantial earthquake recorded in the Caribbean occurred in 1946 (magnitude 7.8) near the Dominican Republic. Historical records indicate that larger earthquakes may have transpired earlier. The area has also experienced numerous tsunami events, emphasizing the seismic threat; notably, the 1867 quake produced a notable tsunami surge in the U.S. Virgin Islands.

Since the devastating 2010 Haiti earthquake, which resulted in approximately 160,000 fatalities, over 30 significant earthquakes have affected the Caribbean. The recent event on February 8 was associated with the same tectonic boundary that generated other recent earthquakes, including a 7.7 magnitude quake off Cuba in 2020.

The February earthquake triggered an immediate tsunami alert, highlighting the efficiency and complexity of our tsunami warning systems. The formal notifications prompted evacuee warnings, with initial estimates predicting tsunami surges across various locations. However, given the complexity of alerts across multiple nations, maintaining clarity is essential for effective public response.

The tsunami warning system faced challenges during this event; thus, improvements are essential for streamlining communication about threats. The complexity arises from the coordinated actions of multiple agencies and countries, which can confuse emergency responders. Fortunately, only minor tsunami impacts were recorded, providing a valuable learning experience for enhancing preparedness.

In summary, the magnitude 7.6 earthquake in the Caribbean serves as a crucial reminder of the region’s seismic risks and the importance of effective preparedness measures. It emphasizes that while major earthquakes can occur outside the traditionally recognized seismic zones, there remains a need for improved tsunami alert systems to facilitate public safety. The recent event not only reinforces the necessity of learning from such occurrences but also provides insight into the complexities of tsunami responses in a region with multiple governing protocols.
