A 7.7-magnitude earthquake struck Mexico, and tsunami warnings were launched in four States along the Pacific coast. How to prevent tsunami?

Tsunami is a natural disaster and cannot be prevented. We can only do a good job of monitoring and issue early warning notices in advance to reduce the harm of tsunami to human life and property.

Tsunami is an extreme natural disaster, and there is no good prevention method at all. The most effective way for human beings to fight against the tsunami is to monitor the tsunami in advance, predict the time of the tsunami, send out relevant early warning signals and notices, and let people in dangerous areas evacuate as soon as possible, which can reduce the harm of the tsunami to human life and property and reduce losses. People often say that the precursor of a tsunami is an earthquake. There is a time difference between the earthquake and the tsunami, so people can evacuate as soon as possible when the earthquake happens.

The earliest signal before the tsunami was a strong ground vibration, because there was a time difference between it and the arrival of the tsunami. People should make good use of this time difference and stay away from the estuary of the river and the seaside. Residents living by the sea should be prepared to prevent the tsunami when they receive the earthquake report. Usually, a tsunami will arrive a few hours after an earthquake. People who live by the sea for a long time must leave the sea as soon as possible if they find that the tide fluctuates abnormally, or when the sea level drops significantly, huge waves hit, which indicates that a tsunami is about to happen.

If there is a tsunami, the seawater in Qian Hai will recede abnormally, resulting in a large number of fish, shrimp and marine life stranded in the shallows. The scene looks spectacular, but you must not blindly go to the seaside to catch fish or watch the excitement at this time. You should evacuate from the sea quickly and to a safe area inland. Only in this way can you ensure your personal safety and avoid hurting yourself when the tsunami comes.

When the tsunami comes, the water color in the shallow sea will suddenly turn white, there will be a long bright water wall ahead, and the ships on the water will also have severe bumps. At this time, there will be abnormal noise at sea, and a large number of deep-sea creatures such as fish and shrimp will appear in shallow water. These are all signs of the tsunami, so we should evacuate as soon as possible to avoid danger. Don't think about fighting the tsunami, because the tsunami is so destructive that human beings can't fight it at all. If they are facing a tsunami, they will only lose their lives and be in danger.
