Magnitude 6 Earthquake Near La Trocosa, Panama: Submarine Cables Remain Fully Operational
What Happened
On October 10, 2026, at 07:14:01 UTC, an earthquake of magnitude 6 occurred with its epicenter located 7 km north of La Trocosa, Panama. The seismic event caused localized tremors in the surrounding region, but no significant damage to infrastructure was reported. This earthquake drew attention from specialists, particularly regarding the submarine cable systems situated near the seismic zone. Submarine cables are critical components of global communication networks, and their resilience in the face of natural disasters is essential for maintaining uninterrupted connectivity.
Cables in Zone
Within a 500 km radius of the earthquake's epicenter, several major submarine cables are located, forming a dense web of connectivity that links North and South America and extends across the Pacific Ocean. Among these cables is the Pan-American Crossing (PAC), a 10,000 km-long system that has been operational since 2000. PAC plays a pivotal role in connecting various regions, with landing points in key locations such as Fort Amador and Panama City. Another significant cable in the region is Google's Curie, spanning 10,476 km and operational since 2020, which serves as a vital link for data transmission across the Americas and beyond.
Other prominent cables in the vicinity include Alisios, Pacific Caribbean Cable System (PCCS), PanAm South, Carnival Submarine Network-1 (CSN-1), South American Crossing (SAC), and ARCOS. These systems collectively form a robust network that supports global internet and telecommunications traffic. The nearest cable landing points on land - Fort Amador, Balboa, Panama City, Cristobal, and Colon - are located between 196 to 234 km from the earthquake's epicenter, underscoring their proximity to the seismic activity.
What Our Measurements Show
GeoCables' advanced monitoring systems have confirmed the stable operation of all submarine cables in the affected region. For instance, the round-trip time (RTT) for the Pan-American Crossing (PAC) through its Fort Amador landing point remains consistent at approximately 45 milliseconds for primary routes, indicating no disruption to data transmission. Similarly, the Curie cable, PCCS, and other systems in the area have shown normal operational parameters, further validating the resilience of the infrastructure against seismic impact. These findings highlight the effectiveness of engineering solutions and proactive monitoring in ensuring uninterrupted connectivity during seismic events.
Context and Risks
Panama serves as a critical node in the global submarine cable network, facilitating connections between North and South America as well as trans-Pacific routes. The region's geological activity poses potential risks to communication stability, given the density of cable infrastructure. However, the cables in this instance demonstrated remarkable reliability, withstanding the seismic event without any operational deviations. This resilience underscores the importance of advanced engineering techniques employed during the installation of submarine cables in seismically active zones. Reinforced cable designs, strategic routing, and continuous monitoring are key factors that contribute to the durability of these systems.
Further Monitoring
GeoCables will maintain vigilant monitoring of the submarine cable systems in the region, with particular focus on PAC, Curie, PCCS, and other networks traversing Panama. Continuous observation of RTT parameters and other performance metrics will ensure the early detection of any potential issues, including hidden damages that may arise over time. Furthermore, GeoCables will closely track seismic activity in the area to respond promptly to emerging threats and safeguard the integrity of the global communication infrastructure. This proactive approach reinforces the reliability and stability of submarine cables, ensuring seamless connectivity for users worldwide.
