On 30 July, an 8.8-magnitude earthquake and subsequent aftershocks struck near Russia’s Kamchatka Krai, with the epicentre located approximately 133km (82 miles) southeast of Petropavlovsk-Kamchatsky at a depth of 74km (46 miles). This event represents the strongest seismic occurrence in the region since 1952.

The quake triggered tsunami warnings across the Pacific Rim, although most warnings were subsequently downgraded to advisories or lifted. Initial tsunami waves reached up to 4m (13 ft) in southern Kamchatka at Severo‑Kurilsk, where evacuations and structural damage occurred. In Japan, between 900,000 to 1.9 million residents were evacuated across hundreds of municipalities. In Hawaii, wave activity was minor, though evacuation orders were issued for coastal areas; similar alerts covered Alaska and the United States (US) West Coast. Several aftershocks, one reaching magnitude 6.9 and multiple expected up to 7.5, followed the mainshock.

What to Expect: 

Travellers to the most affected areas, including southern Kamchatka and the Kuril Islands in Russia, and the eastern Pacific coast of Japan were advised to anticipate widespread evacuations from low-lying coastal zones. Local authorities mobilised emergency response teams, established shelters and restricted access to vulnerable shorelines. In Kamchatka, structural damage to port facilities and public buildings disrupted essential services and movement. Travellers in Hawaii, Alaska and along the US West Coast faced increased security presence, emergency alerts and temporary closures of coastal parks and beaches. Despite tsunami waves being moderate in many regions, there was a continued risk of subsequent waves and strong aftershocks, necessitating ongoing vigilance and preparedness.
