CAUSES AND TYPES OF TSUNAMI Introduction. The term Tsunami has been derived from a Japanese term Tsu meaning 'harbor' and nami meaning 'waves'. Types of Tsunami. A tidal wave tsunami is a type of tsunami caused by the gravitational pull of the moon and sun on the Causes of Tsunami. A Tsunami can Tsunami "Wave Train" Many people have the mistaken belief that tsunamis are single waves. They are not. Instead tsunamis are "wave trains" consisting of multiple waves. The chart on this page is a tidal gauge record from Onagawa, Japan beginning at the time of the 1960 Chile earthquake. The tsunami on Jan. 15 hit Santa Cruz, California, 12 hours and 12 minutes after the initial eruption in Tonga. Santa Cruz is 5,280 miles (8,528 kilometers) from Tonga, which means that the
The three types of tsunamis are: Local Tsunami-It is a type of tsunami that covers an area of 100km or less. The time duration of this tsunami is less Regional Tsunami-The tsunami which causes destruction in the region covering an area of 1000km of its source is known as Distant Tsunami-The
A tsunami is not a single wave but a series of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive. Tsunamis are not tidal waves. Tsunami waves
All Types of Tsunamis Local Tsunami. A local tsunami is a tsunami that causes damage in relatively close proximity to the tsunami-causing Regional Tsunami. A regional tsunami is one that causes damage from 100 km to 1,000 km from the underwater event that Distant Tsunami. A distant tsunami,
A classic tsunami wave occurs when the tectonic plates beneath the ocean slip during an earthquake. The physical shift of the plates force water up and above the average sea level by a few meters. This then gets transferred into horizontal energy across the ocean's surface. From a single tectonic plate slip, waves radiate outwards in all Tsunami, catastrophic ocean wave usually caused by a submarine earthquake, by a landslide, or by a volcanic eruption. In deep water it travels as fast as 800 km (500 miles) per hour, with enormous wavelengths of more than 500 km (310 miles) but small wave amplitudes of about 30 to 60 cm (1 to 2 feet).
Tele-tsunami/Ocean-wide tsunami/Distant tsunami: A tsunami originating from a source, generally more than 1,000 km or more than 3 hours tsunami travel time from the impacted coastline is called an ocean-wide or distant or tele-tsunami.
