2. Indonesia
Indonesia’s position on the convergence of several tectonic plates makes it highly susceptible to earthquakes, tsunamis, and volcanic activity. The country has over 130 active volcanoes, more than any other nation, and frequently experiences seismic events that threaten densely populated coastal regions.
The 2004 Indian Ocean tsunami remains one of the deadliest natural disasters in history, underscoring Indonesia’s vulnerability. Efforts have been made to improve disaster preparedness and infrastructure resilience.
