Moreover, there are three types of tsunamis based on the scene of the disaster: local, regional and remote. Local tsunamis Here, tsunami waves can reach up to 100 km from the source of origin in less than one hour.
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). Large tsunamis are significant threats to human health, property, infrastructure, resources, and economies. Effects can be long-lasting, and felt far beyond the coastline. Tsunamis typically cause the most severe damage and casualties near their source, where there is little time for warning. 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 The results suggest that New Zealand can expect a tsunami of 16.4 feet (5 m) approximately every 77 years, with a wave of at least 49.2 feet (15 m) approximately every 580 years. Tsunamis over 3.3 There are two types of tsunami generation: Local tsunami and Far Field or distant tsunami. The coastal areas in the Philippines especially those facing the Pacific Ocean, South China Sea, Sulu Sea and Celebes Sea can be affected by tsunamis that may be generated by local earthquakes.

Earthquakes generally occur on three types of faults: normal, strike-slip, and reverse (or thrust). Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults.
What is a tsunami? A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. On September 29, 2009, a tsunami caused substantial damage and loss of life in American Samoa, Samoa, and Tonga. The tsunami was generated by a large earthquake in the Southern Pacific Ocean.
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 .
