Supply-chain Risk Briefing

1) Summary A magnitude 5.5 moderate earthquake occurred in the Mariana Islands at approximately 3:00 AM on April 14, 2026. With a very deep focal depth of 219.99km, surface damage is expected to be limited, and no specific damage reports have been received to date.

2) Supply-chain impact

• Electronic components supply: As the Mariana Islands are U.S. territory adjacent to Guam, temporary inspections may be needed for electronic component relay hubs or data center operations in the region
• Air transport: Potential short-term delays due to safety inspections on transpacific air cargo routes via Guam International Airport
• Maritime logistics: Possibility of temporary operational adjustments by vessels on major Western Pacific shipping routes due to safety confirmation procedures
• Communications infrastructure: Concerns over data transmission delays due to preventive inspections of submarine cables or satellite communication facilities

3) Watch points

• Operational status of Guam International Airport and surrounding port facilities, and normalization of transpacific logistics routes
• Aftershock activity within the next 24-48 hours and inspection results of regional infrastructure facilities including U.S. military bases
