The first sign that a tsunami is approaching shore is often a noticeable and sudden retreat of the ocean water, exposing the ocean floor and reefs. This phenomenon occurs as the tsunami pulls water back before the wave arrives. Additionally, a loud roar or rumble from the ocean may be heard, signaling the impending danger. It's crucial for people in coastal areas to recognize these signs and evacuate immediately.
The water receeds (draws back) into the ocean.
In the context of a natural disaster event, the earthquake typically occurs before the tsunami. This is because the earthquake generates the seismic waves that trigger the tsunami as a series of powerful ocean waves.
