How to avoid the tsunami in coastal areas?

1. The earthquake is the most obvious precursor of the tsunami. If you feel a strong vibration, don't go near the mouth of the sea and rivers. If you hear the report of an earthquake nearby, you should be prepared to prevent the tsunami and pay attention to TV and radio news. Remember, tsunamis sometimes reach thousands of kilometers away from the source a few hours after an earthquake. Second, ships at sea should avoid returning to the port after hearing the tsunami warning. The gap and turbulence caused by the tsunami in the harbor are very dangerous. If there is enough time, the shipowner should take the boat out to sea before the tsunami comes. If there is no time to sail out of the harbor, everyone should evacuate the ships moored in the harbor. 3. When the tsunami lands, the seawater often rises or falls obviously. If you see the sea surface retreating at an unusually fast speed, you should immediately evacuate to a higher place inland. Everyone should have a first aid kit, which should contain enough medicine, drinking water and other necessities for 72 hours. This applies to tsunamis, earthquakes and all sudden disasters.
