M5.2 earthquake · 2 km WSW of Kablalan, Philippines
The submarine cable network remains stable with no anomalies detected over the past 24 hours from our 1842 latency checks across 647 cables. This confirms that the network is operating without issues.
On June 13, 2026, a M5.2 earthquake occurred near Kablalan, Philippines, within proximity to some of our monitored submarine cables. Despite this seismic event, all relevant cables with landing points within 350km are functioning normally and show no impact in our latency measurements.
M5 earthquake · 30 km SSW of Daliao, Philippines
The submarine cable network remains stable with 1876 latency checks conducted over the past 24 hours revealing no anomalies and zero active alerts. This ensures that data flows smoothly across our global network.
Contextually, a M5 earthquake occurred on June 12, 2026, near Daliao, Philippines. The cables with landing points within 350km of the event are operating normally, as indicated by our latency measurements which show no impact from the seismic activity.
M4.5 earthquake · 6 km SSE of Pangyan, Philippines
A magnitude 4.5 earthquake occurred on June 12, 2026, approximately 6 km southeast of Pangyan, Philippines. The event is located within a radius of 350km from several submarine cables with landing points in the region.
Our monitoring indicates that four submarine cables—Apricot, Asia Connect Cable-1 (ACC-1), Bifrost, and SEA-US—are potentially affected by the seismic activity. These cables land at Davao, Philippines, which is 163km from the epicenter. We have observed latency anomalies in these cables: Apricot has an average latency of ~160ms with 11 checks over a week, ACC-1 shows ~226ms with 92 checks, and Bifrost measures ~204ms with 41 checks. SEA-US also reports similar latency issues at ~203ms with 11 checks. The other cables in the vicinity—Palapa Ring Middle, PLDT Domestic Fiber Optic Network (DFON), Converge Domestic Submarine Cable Network (CDSCN), and Philippine Domestic Submarine Cable Network (PDSCN)—are not actively measured for latency changes due to their greater distance from the earthquake's epicenter.
M4.5 earthquake · 85 km S of Pýrgos, Greece
A magnitude 4.5 earthquake occurred on June 11, 2026, approximately 85 km south of Pýrgos, Greece. This event is within a range that could potentially impact submarine cable networks.
Our monitoring indicates that the 2Africa and India Europe Xpress (IEX) cables, which both land at Tympaki, Greece, are in close proximity to the earthquake's epicenter, being about 98 km away. Latency measurements for these cables show an average of ~189ms with 140 checks over seven days for 2Africa and ~134ms with 11 checks over seven days for IEX. No active alerts are currently in place, but we continue to monitor the situation closely.
