This video compilation of ice tsunami around the world is amazing. Enjoy!
An ice shove is a surge of ice from an ocean or large lake onto the shore. Such shoreline ice pileups are caused by ocean currents, strong winds, or temperature differences pushing ice onto the shore, creating piles up to 12 metres (40 feet) high. Some have described them as ‘ice tsunamis’, but the phenomenon works like an iceberg. Ice shoves can damage buildings and plants that are near to the body of water.
