A powerful magnitude‑8.8 earthquake struck off Russia’s Kamchatka Peninsula on July 30, prompting tsunami waves exceeding 3 m (9.8 ft) and peaking at 5 m (16.4 ft) in Severo‑Kurilsk.

The town's port was flooded, causing widespread damage and evacuation of around 2,000 residents. Authorities declared a state of emergency throughout the North Kuril District.

Buildings including a fish-processing plant and a kindergarten were severely impacted. Connectivity disruptions were reported, though no casualties have been confirmed yet.

Waves Reach Japan and U.S. Pacific Coast

Japan recorded tsunami waves up to 60 cm (≈2 ft) along Hokkaido, with over 1.9 million people under evacuation advisories. Ferry services and transportation corridors were suspended.

Hawaii saw waves surfacing up to 5.7 ft (≈1.7 m) on Maui and 4–5 ft in Oahu. Coastal parking lots flooded, flights canceled, and roads congested as residents moved to higher ground. The tsunami warning was later downgraded to an advisory.

Along the U.S. West Coast, including Northern California, small waves (1–1.6 ft) were recorded at locations like Arena Cove and Crescent City. Officials warned of unpredictable currents, especially at high tide.

Aftershocks and Ongoing Alerts

The earthquake is considered one of the strongest in the region since 1952. Multiple aftershocks, some as high as magnitude 6.9, are expected for days. Authorities across affected zones—from Japan to New Zealand—have issued ongoing tsunami alerts and urged coastal residents to stay clear of the water.

What Comes Next

Emergency services across the Pacific remain on high alert. Local infrastructure—including ports, coastal roads, and power grids—is being assessed.

Residents in affected areas are advised to stay at safe elevations, avoid beaches and harbors, and monitor official updates until the tsunami threat is lifted.
