Large waves and surges that threaten coasts, including tsunamis, megatsunamis, storm surges, rogue waves and the submarine landslides that can trigger tsunamis. A topic belongs here when its cited article describes a tsunami, giant wave or surge. It excludes steady currents and sea ice. Their damage depends on the size of the wave and the shape of the coast it reaches. Warning systems, sea walls and evacuation plans are built around the records these events have left in coastal communities.
