What is the highest wave in the world?

Waves that cause disasters at sea are called disastrous waves. Usually, catastrophic waves refer to waves with a wave height of 6 meters or more. Because the waves with a wave height of more than 6 meters pose a threat to the vast majority of ships sailing in the world's oceans.

The highest recorded wave was 1958 in Litua Bay, Alaska, USA. The wave was over 5 10 m, which was caused by the tsunami. According to records, the maximum seismic wave is 197 1, which occurred near Ishigaki Island in Ryukyu Islands on April 24th, with a height of about 85 meters. 850 tons of coral reefs 2 1 km away were photographed, and the observed speed once reached 789 kilometers per hour.

Wave warning level

The warning levels of ocean waves are divided into four levels, I, II, III and IV, which respectively mean particularly severe, severe, heavy and average, and the colors are red, orange, yellow and blue in turn.

Wave level I early warning (red): Affected by tropical cyclone or temperate weather system, it is expected that the effective wave height of 6.0m will be reached or exceeded in the affected offshore waters in the future, or that the effective wave height of 14.0m will be reached or exceeded in other affected waters. Wave level I early warning (red) should be issued to start the emergency response of wave disaster.

Wave level II early warning (orange): Due to the influence of tropical cyclone or temperate weather system, it is predicted that there will be an effective wave height of 4.5m-6.0m (excluding) in the affected offshore waters in the future, or an effective wave height of 9.0m- 14.0m (excluding) in other affected waters, and a wave level II early warning (orange) will be issued to start the wave level II emergency response.

Wave level III early warning (yellow): Due to the influence of tropical cyclone or temperate weather system, it is predicted that there will be an effective wave height of 3.5 -4.5 meters (excluding) in the affected offshore waters in the future, or an effective wave height of 6.0 -9.0 meters (excluding) in other affected waters. Wave level III early warning (yellow) should be issued to start the wave level III emergency response.

Class IV wave forecast (blue): Affected by tropical cyclone or temperate weather system, when the predicted effective wave height in the future affected offshore waters is 2.5m-3.5m (excluding), class IV wave warning (blue) will be issued to start class IV wave emergency response.

Navigation at sea is very dangerous, and a swell of 4-5 meters is formed on the sea surface. Ships are prone to danger in this kind of wind and waves, so it is very dangerous to sail at sea when the waves are 4-5 meters high.
