What is a Tsunami?
A tsunami is a series of sea waves commonly generated by under-the -sea earthquakes and whose heights could be greather than 5 meters. It is erroneously called tidal waves and sometimes mistakenly associated with storm ssurges. Tsunamis can occur when the earthquake is shallow-seated and strong enough to displace parts of the seabed disturb the mass of water over it.
Some natural signs of an approaching tsunami:
- A felt earthquake
- Unusual sea level change-sudden water sea retreat or rise
- Rumbling sounds of approaching waves
