6.9 Magnitude Earthquake Near Vanuatu: Tamtam Cable Remains Fully Operational
Earthquake off the Coast of Vanuatu
On October 24, 2026, at 05:31 UTC, an earthquake with a magnitude of 6.9 occurred. The epicenter was located 197 km northwest of Port Olry, Vanuatu. This event served as another reminder of seismic activity in the region known as the Ring of Fire in the Pacific Ocean.
The earthquake raised concerns about potential impacts on submarine cable infrastructure near the epicenter, particularly the Tamtam cable, which is crucial for ensuring communication for Vanuatu and neighboring islands.
Tamtam Cable in Earthquake Zone
The Tamtam cable, commissioned in 2027, runs 411 km from the earthquake epicenter. This cable belongs to operator Prima and connects Luganville on Espiritu Santo Island (240.1 km from the epicenter) with other regions. Tamtam is an important element of Vanuatu's telecommunications infrastructure, providing international connections and internet access for the island nation.
Despite its proximity to seismically active zones, the cable was designed with possible natural disasters in mind, making it resilient to such events.
Monitoring Network Results
According to our data, the round-trip time (RTT) for the Tamtam cable is approximately 55 milliseconds. After the earthquake, we did not observe significant changes in the RTT or other network performance metrics. This indicates that the cable infrastructure continues to operate normally.
The absence of deviations confirms that the cable withstood the seismic impact, indicating its reliability and resilience to external factors.
Significance for Global Traffic
The region of Vanuatu, located in the southern Pacific Ocean, relies on submarine cables to maintain communication with the rest of the world. The Tamtam cable is crucial for maintaining internet connectivity for residents and businesses on the islands. Its resilience to earthquakes confirms its ability to provide stable service even under natural disasters.
If the cable had been damaged, it could have led to significant service disruptions in the region's internet services, highlighting the need for backup routes and additional protective measures for infrastructure in seismically active areas.
Plans for Further Monitoring
We will continue to closely monitor the condition of the Tamtam cable and other submarine communication lines in the region. Special attention will be given to any data transmission delays, as well as any changes in network structure that may be related to current seismic activity.
In addition, we will track any subsequent earthquakes in the Vanuatu area to promptly assess their impact on underwater infrastructure. Our goal is to provide timely information to operators and users about the state of the network.
