What is a Tsunami?


According to https://oceanservice.noaa.gov/facts/tsunami.html, “A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions.” The thing is, these aren’t exactly the everyday waves you would see at a beach. Tsunami waves are gigantic and can travel very fast depending on how far they are away from the shore. Some waves can travel as fast as 500mph, this is equivalent to the speed of a jet. The speed and size are determined by the distance between the shore and the wave. For example, if a tsunami wave is farther away from shore it will increase height as it gets closer to the shore. Tsunami waves tend to increase in height as the water gets shallower, so closer to shore. Speedwise, when the wave approaches the shore it will slow down, but get taller. Some destructive and dangerous waves may reach up to 100 feet, but most usually stay at the 10 feet mark.
