Who is at the most risk of tsunami?

Coastal populations in low-lying areas near tectonic plate boundaries are at the highest risk of tsunamis. Countries along the Pacific Ring of Fire, such as Indonesia, Japan, and Chile, face significant threats due to frequent seismic activity. Additionally, islands and communities with limited warning systems and inadequate infrastructure are particularly vulnerable. Overall, those living in proximity to the ocean in seismically active regions face the greatest danger.
