How to tell if a tsunami is coming?

Identifying Tsunami Warnings

Indicators of an approaching tsunami include experiencing a prolonged or intense earthquake, hearing a loud noise reminiscent of a train or airplane originating from the ocean, and observing abnormal ocean behavior. The water may appear as if it's quickly surging upward, resembling a flooding phenomenon or even a towering wall of water. Alternatively, you might notice the ocean retreating suddenly, revealing the ocean floor, coral reefs, and marine life, akin to an extreme low tide.
