Energy supply, refining, and storage facilities are often in coastal locations. Services may be made more resilient by incorporating higher engineering specifications designed for tsunami scour, lateral pressure, buoyancy, debris impact and fire. Around the world there is increasing recognition that avoiding development in the most frequently tsunami (or river flood or storm surge) inundated areas is one of the most effective means of managing future losses to natural hazards. Consider which dependencies are vulnerable to tsunami. Its more like the ocean turns into a white water river and floods everything in its path..

Very small tsunamis, non-destructive and undetectable without specialized equipment, occur frequently as a result of minor earthquakes and other events. The tsunami took just over 4 hours to travel over 1,000 miles (1,600km) to Cornwall in the United Kingdom. Most common dependencies include energy supply (especially electric) and communications. Fuel is often stored in coastal tank farms, which can be heavily damaged by tsunami. It takes an external force to start a wave, like dropping a rock into a pond or waves blowing across the sea. For example, backup power generation, and long term fuel supply availability. The sheer scale of the destruction was just mind-boggling..
