Tsunamis are fast-moving, long-wavelength water waves generated by underwater disruptions like earthquakes or landslides. They have low amplitudes in deep water but can grow significantly in shallower waters, potentially leading to destructive outcomes at the coast.
A tsunami is a fast-moving, long-wavelength water wave generated by a sudden displacement of water due to undersea landslides, earthquakes, or volcanic activity. They are not caused by tides but by energetic events affecting the sea floor. When approaching shore, a tsunami's speed diminishes, but its wave height can dramatically increase, reaching over 30 meters high.
In deep ocean water, tsunamis have low amplitude and long wavelengths, making them almost unnoticeable until they reach shallow waters. The distance between wave crests at sea can be calculated based on the speed of the tsunami and the rate of wave crests approaching the shore, providing insights into their behavior in open waters.
Despite their low amplitudes in deep oceans, tsunamis can travel at incredible speeds, up to 500 mph, and have the potential to cause catastrophic damage when they reach the coast, as seen in past devastating events like the Indian Ocean tsunami in 2004.
