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. Dec. 2, 2023. A 7.6-magnitude earthquake struck the eastern parts of the Philippines on Saturday, leading to tsunami warnings across the region and as far as the southern part of Japan, nearly 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). There are three distinct types of tsunami. The type you encounter depends on the distance you are from the place where it is generated. Distant tsunami: Are generated from a long way away, such as from across the Pacific in Chile. In this case, we will have more than three hours warning time for New Zealand. 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 Essentially, they are dynamically equivalent to seismic tsunamis, the only differences being 1) that meteotsunamis lack the transoceanic reach of significant seismic tsunamis, and 2) that the force that displaces the water is sustained over some length of time such that meteotsunamis cannot be modelled as having been caused instantaneously. .
