Navigating the Waves: How Cruise Ships Are Affected and Re-Routed by Tsunami Warnings

An 8.8 magnitude earthquake off the Pacific coast of Russia instigated tsunami warnings and evacuation alerts, affecting cruise ships across the Pacific Ocean on July 30, 2025. Following the issuance of the National Weather Service’s tsunami advisory, several vessels in Hawaii, Alaska, and along the U.S. West Coast were compelled to depart their ports earlier than scheduled to prioritize safety.

The Norwegian Cruise Line’s Pride of America was notably affected, leaving Hilo, Hawaii, two hours ahead of its planned departure time at 4 p.m. local time. A company representative stated that the ship had to comply with local emergency procedures. Passengers were immediately notified via SMS about the necessary evacuations and instructed to seek higher ground if they were unable to return to the ship promptly.

Those on board excursions were taken to a local high school designated as a safe location in Hilo, where refreshments were provided while they awaited the situation’s resolution. To ensure safety amid the tsunami warnings, the Pride of America remained at sea.

As the tsunami warning was lifted, Norwegian Cruise Line announced a gradual reopening of impacted ports, although Hilo Harbor required a safety assessment before it could be cleared for vessel returns. This assessment was scheduled for the early morning of July 30, 2025.

This incident also impacted coastal areas of California, where tsunami waves were recorded in Monterey and San Francisco without causing significant damage. The Cruise Lines International Association emphasized their commitment to passenger safety and noted the cruise industry’s well-preparedness to respond to such emergencies.

The situation is being monitored closely, with ongoing updates expected to be communicated to passengers.
