El Segundo: A Crucial Hub for Global Submarine Cables

El Segundo: Where Cables Converge

El Segundo, located off the coast of California (latitude 34.0000, longitude -118.5000), is a critical hub for submarine cable infrastructure. This location was chosen strategically: it is close to major U.S. tech hubs like Los Angeles and provides convenient access to Pacific routes. Geographically, it is positioned to efficiently connect North America with Asia, Oceania and South America.

Proximity to major data centers and telecommunications nodes makes this point strategically vital for the global internet. However, the concentration of cables in one location also creates a vulnerability that requires attention.

What Passes Through El Segundo

This chokepoint is traversed by 13 submarine cables, including some of the longest and most important routes in the world:

• Project Waterworth: 50,000 km, one of the largest global connectivity projects.
• Tata TGN-Pacific: 22,300 km, connecting the U.S. with Asia.
• Asia Connect Cable-1 (ACC-1): 19,000 km, linking North America and Asia.
• JUPITER: 14,557 km, providing low latency between Japan, the Philippines and the U.S.
• SEA-US: 14,500 km, connecting the U.S. with Southeast Asia via Guam.
• Southern Cross NEXT: 13,700 km, linking the U.S., Australia and New Zealand.
• ORCA: 12,482 km, covering routes between the U.S. and Oceania.
• Pacific Light Cable Network (PLCN): 11,806 km, connecting the U.S. with Hong Kong and the Philippines.
• Curie: 10,476 km, linking the U.S. and South America.
• Unity/EAC-Pacific: 9,620 km, connecting the U.S. with Japan.

The list also includes cables such as Tabua, Zayo Festoon and Unity, although their exact lengths or roles remain partially undisclosed in available data.

Who Relies on This Hub

El Segundo serves numerous countries and regions. In the event of cable disruptions here, significant connectivity issues would be felt by:

• The U.S.: as the country hosting data centers and transit nodes.
• Japan, The Philippines, Indonesia, Guam, Micronesia, Palau: key Asia-Pacific nodes.
• Australia and New Zealand: users of Southern Cross NEXT.
• South America (Panama, Brazil): via Curie.
• South Africa and India: through globally spanning routes.

Additionally, countries like Timor-Leste and Fiji depend on stable connectivity through this chokepoint.

Risks: From Earthquakes to Sabotage

The risks in the El Segundo area are diverse:

• Seismic activity: California's coastline is known for high tectonic activity. An earthquake could damage cables on the ocean floor.
• Ship anchors: proximity to the Port of Los Angeles increases the risk of cable damage from improper anchor use.
• Fishing: trawling can accidentally snag cables.
• Sabotage: cables remain vulnerable to intentional attacks, especially given their strategic importance.
• Geopolitics: tensions between nations could lead to deliberate damage or sanctions affecting cable operations.

The specifics of the Tabua and Zayo Festoon cables mentioned in the data require further analysis: their lengths are listed as -1 km, which may indicate data errors or incomplete information.

How GeoCables Monitors the Situation

GeoCables actively monitors the status of cables in the El Segundo area. The following approaches are used:

• Latency monitoring: tracking changes in data transmission speeds to identify potential damage.
• Ship tracking: analyzing the routes of vessels near cables to prevent incidents.
• Seismic activity analysis: using earthquake data to assess potential cable damage.

El Segundo remains one of the most critical points for the global network, and its security demands constant attention.
