Based on related reporting.

Research from related reporting describes the July 2025 Kamchatka earthquake and tsunami alerts, but the supplied excerpts do not substantiate the claim of 4-meter waves or heavy infrastructure losses. One report says Japan issued an advisory for waves up to 1 meter; another gives the quake’s magnitude as 8.8 rather than 8.7.[S2][S3]
