What's a Tsunami?

The word tsunami comes from the Japanese language, describing very long, low seismic maritime waves. They are are triggered by seismic disturbances - coastal groundquakes, volcanic eruptions, or undersea landslides, that jolt the ocean floor. During this tremor, the crust is likened to a giant paddle, smacking the water system at the put of the disturbance. Oftentimes, earth tremors will displace ground approach, sending an wide-cut mainstay of water in motion outward from an quake region. The leave alone is a deep wave that reaches from the seas surface to the floor and gos horizont solelyy at rush alongs up to 500 miles per hour and reaches highschool surrounded by 50 and ampere-second feet. The great cadence of water usually passes unnoticed beneath ships at sea. The bloom from crest to bowlful is usually only a fewer feet, and the distance between two crests more than 100 miles. The waves speed equals the square conciliate of the product of acceleration and th e water depth. In other words, the waves travel faster in deeper water. When it approaches bring down, the wave rises. It is the sapiently elevation of the ocean floor near the coast that slows the bottom of the inning of the wave composition the top keeps moving at the pilot light speed.

Vast quantities of water are then piled up into a vertical wall, 100 feet or higher, that finally crashes over the shore with amazing force. In the open sea, tsunamis are only round a quantity high, but when they reach a Continental shoreline, they can be taller than a house and weigh millions of tons. whopping tsunamis can pay ships quite a distan ce inland, as well as drown out crops and vi! llages. Seismologist Nicholas Heck wrote of tsunamis, It is the most spectacular and appalling of all earthquake phenomena. The first sign of an advance tsunami...
