I. If you detect signs of a tsunami in advance, you should do the following:
1.Loudly warn and notify those around you, ensuring they also become aware of the impending danger.
2.Run to higher ground, ideally reaching a hill or mountain.
3.Finding a sturdy building with strong resistance is also good. It is said that the safest place in a house is the bathroom, as this area is generally smaller and the distance between the four pillars is also small, making it relatively sturdy.
II. If you unfortunately fall into the water during a tsunami, please remember the following self-rescue and mutual rescue knowledge:
1.Try to grab floating objects such as wooden boards, while avoiding collisions with other hard objects.
2.Do not raise your hands or struggle excessively in the water; minimize your movements. Floating on the water's surface and drifting with the waves can prevent sinking and conserve energy.
3.If the sea water is cold, do not remove your clothes.
4.Avoid swimming to prevent rapid loss of body heat.
5.Do not drink seawater. Seawater will not quench your thirst and can cause hallucinations, leading to mental instability and even death.
6.Try to stay close to other people in the water. This makes it easier to help and encourage each other and increases your visibility to rescuers.
7.Prolonged immersion in seawater can cause body heat loss and a drop in body temperature. When a drowning person is rescued and brought ashore, it is best to place them in warm water to restore their temperature. If that is not possible, wrap them in blankets, coats, or other insulating materials. Avoid local heating or massage, and do not give the person alcohol, as it will cause heat loss. Giving the person some sugar water can be beneficial by replenishing fluids and energy.
8.If the person is injured, administer first aid measures such as stopping bleeding, bandaging, and immobilizing. Severely injured persons should be sent to the hospital promptly.
9.Remember to promptly clear the person's nasal cavity, mouth, and stomach of any inhaled substances. Specifically, place the person's stomach on your thigh and press on their back to expel seawater and other inhaled substances. If their heartbeat and breathing stop, immediately alternate between mouth-to-mouth resuscitation and chest compressions.
