Earthquake Statistics in Cartagena

In the past 10 years, there have been a total of 74 earthquakes with a magnitude of four or above within 300 km of Cartagena. The majority of these earthquakes have a magnitude of 4, accounting for 90.54% of the total. Earthquakes with magnitudes of 5 and 6 were less frequent, at 8.11% and 1.35% respectively. There have been no earthquakes with a magnitude of 7 or above in this region.

Strongest Earthquakes in Cartagena

The strongest earthquake recorded in Cartagena in the past 10 years had a magnitude of 6.5. This powerful earthquake occurred on May 24, 2023, approximately 238 kilometers southwest of Cartagena. It struck at a depth of 13 km, causing significant shaking and potential damage.

Since 1900, there have been no earthquakes with a magnitude greater than 6.5 in the region surrounding Cartagena, indicating that the 6.5 magnitude earthquake is the largest event recorded in recent history. Despite the relatively infrequent occurrence of major earthquakes, it is important to remain prepared and informed about seismic activity in the area.

Nearest Earthquakes to Cartagena

When it comes to earthquakes in Cartagena, it’s important to consider the nearest seismic activity and its potential impact on the region. The earthquakes closest to Cartagena have their epicenters in various locations, including Santa Rosa, Bolívar, Turbaco, Bolívar, Turbaná, Bolívar, and Villanueva, Bolívar. These cities are located approximately 210 km to 220 km from Cartagena.

These earthquakes contribute to the overall seismic activity and potential hazard in the vicinity of Cartagena. While they may not directly affect the city, their proximity highlights the need for preparedness and vigilance in the face of potential seismic events.

Understanding the location and magnitude of nearby earthquakes is crucial for assessing the seismic risk in Cartagena and implementing appropriate measures to ensure the safety and well-being of its residents.

Tectonic Regimes in the Caribbean Plate

The perimeter of the Caribbean plate exhibits a diverse and complex range of tectonic regimes. This involves the convergence of multiple major plates, including North America, South America, Nazca, and Cocos. The presence of inclined zones of deep earthquakes, ocean trenches, and volcanic arcs indicates subduction of oceanic lithosphere along the Central American and Atlantic Ocean margins of the Caribbean plate. The tectonic activity in the region contributes to the seismicity and geological characteristics of Cartagena and its surrounding areas.

Understanding the tectonic regimes in the Caribbean plate is essential in assessing the earthquake hazard in Cartagena. The convergence of these major plates creates a dynamic environment with significant geological processes. The subduction of oceanic lithosphere along the plate boundaries gives rise to earthquakes and volcanic activity in the region.

Locked Patch and Earthquake Risk in Cartagena

Data from a GPS network in Colombia has revealed a shallow and fully locked patch in the Caribbean subduction zone south of Cartagena. This locked patch indicates a potential earthquake risk for the northwest region, including Cartagena. The presence of a locked patch suggests that stress is accumulating along the fault, resulting in the potential for a large earthquake to occur.

The locked patch in the Caribbean subduction zone is of particular concern due to the region’s historical seismic activity. Studies have shown that the locked patch is capable of generating a magnitude 8.0 earthquake every 600 years. Such an earthquake could have significant consequences for the coastal areas of Cartagena and surrounding communities.

In order to fully evaluate the earthquake hazard potential associated with the locked patch, further geological mapping and studies on past tsunamis and large earthquakes are necessary. By understanding the geological characteristics and historical seismicity of the region, we can better assess and mitigate the earthquake risk in Cartagena.

A crucial step in monitoring and assessing the earthquake risk is increasing the coverage and real-time operation of the GPS network in Colombia. This will provide valuable data for ongoing research and help scientists and authorities make informed decisions regarding earthquake preparedness and response in Cartagena.

Complex Tectonic Zone and Historical Earthquakes

Cartagena, located in a complex tectonic zone, is situated where the Caribbean, Nazca, and South American plates, along with smaller tectonic blocks, converge. This convergence of plates results in a dynamic geological environment with the potential for seismic activity. Historically, the northern part of Colombia has experienced earthquakes. However, recent studies have shown disparities between the magnitudes estimated by historical records and those determined through scientific analysis. Additionally, the occurrence of tsunamis in the region does not align with the historical record. This discrepancy underscores the importance of further research and the need to gather evidence regarding past tsunamis and large earthquakes in the Cartagena area.

Continued investigation into the historical earthquakes and geological characteristics of Cartagena will contribute to a better understanding of the region’s seismic hazard and improve preparedness measures for future events.

Conclusion

In conclusion, Cartagena, Colombia experiences a moderate level of seismic activity, with an average of 7 earthquakes per year within a 300 km radius. The strongest earthquake recorded in the past 10 years had a magnitude of 6.5, indicating a significant but not catastrophic level of seismicity in the region.

However, the presence of a locked patch in the Caribbean subduction zone near Cartagena raises concerns about the potential for a large earthquake and tsunami. This highlights the need for further studies and ongoing monitoring to fully understand and assess the earthquake hazard in Cartagena and its surrounding areas.

By gathering more data and conducting in-depth geological mapping, we can gain a better understanding of the seismic risks and develop effective strategies for mitigating potential damages. It is crucial to prioritize the expansion and real-time operation of the GPS network in Colombia to enhance early warning systems and facilitate prompt response measures.
