Signs along the shoreline
Fortunately, a few natural warning signs can help you understand that a tsunami is approaching and they can be easily recognized. They include:
strong ground shaking from an earthquake: if you are on the coast and there is an earthquake, it may have caused a tsunami, so escape immediately to higher ground or inland, avoiding river valleys;unusual sea-level fluctuations: a noticeable rapid rise or fall in coastal waters is a sign that there may be a tsunami approaching. If you see the water recede quickly and unexpectedly from a beach exposing the ocean floor (the so-called drawback) or a sudden rise of the sea level, escape immediately to higher ground or inland, avoiding river valleys;abnormally huge wave: the first wave in a tsunami wave train is usually not the largest, so if you see an abnormally huge wave, even bigger waves could be coming soon. Run immediately to higher ground or inland, avoiding river valleys;loud ocean roar: if you hear a roaring sound offshore, similar to that of a train or jet aircraft, a tsunami may be approaching, so escape immediately to higher ground or inland, avoiding river valleys.
