Awareness of Tsunami Warning Signs is vital when travelling through or living in tsunami prone areas. An earthquake is a natural tsunami warning. If you feel a strong quake, do not stay in a place where you may be exposed to a tsunami. Listen to the radio or television for any information or alerts. If you are subscribed to TsunamiSMS make sure your mobile phone is always switched on and that the ring tone is loud enough to hear, even when you are asleep.

Witnesses have reported that an approaching tsunami is sometimes preceded by a noticeable fall or rise in the water level. If you see the ocean receding unusually rapidly or far it's a sign that a big wave may be on its way. Go to high ground immediately or make your way at least five kilometers inland.
Remember that a tsunami is a series of waves and that the first wave may not be the most dangerous. The danger from a tsunami can last for several hours after the arrival of the first wave. A tsunami wave train may come as a series of surges that are five minutes to an hour apart. The cycle may be marked by a repeated retreat and advance of the ocean. Stay out of danger until you hear it is safe.
