Which of the statements below are the natural signs of impending tsunami?

I. A severe, strong and load ground shaking.

II. Abnormal Ocean activity where there is a rapid and unexpected recession of water levels below the expected tides.

III. Unusual disturbance or roaring and load sound like a train or a fast-flying jet plane from the ocean floor.

IV. The ocean floor would look like a fast-rising flood or a wall of water where it can drain away suddenly, exposing the ocean floor, reefs and fishes on the sea bottom.
