The core hazard posed by tsunamis is their sudden appearance, which makes preparedness essential for coastal communities. An expert from the Institute of Applied Physics explains that Russia’s most vulnerable coastline for tsunami activity lies along the Far East. This insight highlights a region where large waves generated in the Pacific can reach populated shores with little forewarning, underscoring the critical role of early warning systems and readiness. The discussion notes that the Far East coast sits near active plate boundaries and tectonic zones where ocean energy can accumulate quickly, sometimes translating into powerful surges that affect towns, ports, and infrastructure. This view aligns with a broad scientific consensus on ocean dynamics and regional seismic activity, reinforcing the need for continuous monitoring and risk-reduction planning to protect residents and visitors from sudden sea changes. The interview, focused on professional insights, emphasizes the real-world implications of tsunamis for large coastal populations in areas facing Pacific-origin threats.
