What is a tsunami?
A Tsunami is a series of sea waves commonly generated by under-the-sea earthquakes and whose heights could be greater than 5 meters. It is erroneously called tidal waves and sometimes mistakenly associated with storm surges. Tsunamis can occur when the earthquake is shallow-seated and strong enough to displace parts of the seabed and disturb the mass of water over it.
SOME NATURAL SIGNS OF AN APPROACHING LOCAL TSUNAMI
1) A felt earthquake.
2) Unusual sea level change: sudden sea water retreat or rise.
3) Rumbling sound of approaching waves.
