自然资源部海啸预警中心：堪察加海域地震海啸不会对我国造成灾害性影响

Core Viewpoint - A strong earthquake occurred off the eastern coast of the Kamchatka Peninsula, triggering a tsunami warning, but it is not expected to cause significant damage to China's coastal areas [1] Group 1: Tsunami Warning Details - The earthquake occurred on July 30, 2025, at 7:24 AM Beijing time, prompting the issuance of a yellow tsunami warning by the National Natural Resources Department [1] - The yellow warning indicates a tsunami wave height of 0.3 to 1 meter, with an expected wave height of 0.3 meters along China's mainland coast, posing no disaster risk [1] - Monitoring stations reported tsunami waves of 1 meter at Midway Atoll, 0.9 meters at buoy 21416, and 0.4 meters at Japan's Ofunato station, with potential impacts on Taiwan's eastern coastal areas [1] Group 2: Tsunami Risk Mitigation - The natural island chain and reefs in the Pacific effectively dissipate tsunami energy, significantly reducing the impact on China's coastal regions [2] - The East China Sea and Yellow Sea, characterized by broad continental shelf areas, further diminish tsunami wave energy due to shallow water topography [2] - Historical data indicates that nearshore earthquakes in China are generally of lower magnitude, with rare occurrences of magnitude 8 or higher, which reduces tsunami risk [2]
