Can lighthouse withstand tsunami?

Risk is the sum of danger and exposure – a Great Lakes lighthouse at water level may be in more danger of destruction by tidal wave than a seacoast light high on a promontory, but the risk is almost nil because exposure to tsunamis is vanishingly small in the inland seas.

How do lighthouses survive storms?

With advanced notice, such as with a hurricane, lighthouse keepers will board windows and block openings where water can enter. They may also move records and inventory to keep away from possible water damage.
