Types of Tsunami Waves
There are two types of tsunamis: Local and Teletsunamis. Local tsunamis are waves affecting coastlines close to the generating area (whether by tectonic or landslide activity). They may be quite severe but only affect a limited area.
Has a mega tsunami ever happened?
– No such event – a mega tsunami – has occurred in either the Atlantic or Pacific oceans in recorded history. NONE. – The colossal collapses of Krakatau or Santorin (the two most similar known happenings) generated catastrophic waves in the immediate area but hazardous waves did not propagate to distant shores.
Do Tsunamis have names?
Tsunamis have no names, at least not yet. Nor do earthquakes or floods. … The system of naming of Atlantic cyclones (known as hurricanes or typhoons), is a fairly old practice, but giving names to cyclones that originate in the northern Indian Ocean and affect South Asian countries began only at the turn of this century.
