Diving is an underwater adventure activity. In the underwater world, we will unfortunately face some emergencies, such as earthquakes. Earthquakes are an unpredictable natural disaster, so how should we respond when we encounter one while diving? Here are some key guidelines and advice to help you cope with earthquakes while diving.
1. Underwater earthquake early warning conditions
When an earthquake occurs, underwater divers can hear the sound before feeling the vibrations. Low-frequency sounds can cause poor visibility and sand turbulence, making navigation challenging for divers.
2. The impact of underwater earthquakes on divers
Divers may be separated from their partners due to strong currents caused by earthquakes. Shallow water is more likely to generate strong waves, which can have a greater impact on divers. Before an earthquake, a dive site may experience unusual calm or a lack of fish.
3. Safety measures during earthquakes
Safety measures in different situations:
Before diving (without entering the water): Evacuate the coast.
Surfaced but not yet dived: bite the regulator, hold on to a buddy or buoy, avoid danger areas (do not swim close to shore).
While diving: stay calm, stay united, observe changes in depth, and seek shelter.
Stay calm: When an earthquake strikes, the first step is to stay calm and think calmly. Don't panic, as panic only increases danger and confusion. Try to keep a cool head so that you can make the right decisions.
Assess the situation: During an earthquake, first assess the situation around you. Watch for drastic changes in water flow, sliding of stones or sediment, etc. Based on your assessment, make appropriate responses.
Resurface safely: If you experience an earthquake while diving, your first priority is to surface as quickly as possible. Stay calm, ascend gradually, and follow correct ascending procedures. Make sure you and your diving partner can both come up safely.
Protect Yourself: When you experience an earthquake underwater, it is crucial to protect your body. Try to avoid hitting solid objects and use your arms and hands to protect your head and body.
Stay in touch with your dive partners: During an earthquake, it is important to stay in touch with your dive partners. Make sure you maintain visual and auditory contact with them and follow a predetermined response plan.
4. Post-earthquake treatment
After an earthquake, divers may encounter debris and turbid waters. The importance of staying calm. Staying in the water avoids potential dangers on land.
Stay away from the seabed and rocks: During an earthquake, the seabed and rocks underwater can shift violently, possibly causing collapse or sliding. Try to stay away from these areas and find a relatively safe location.
Experiencing an earthquake while diving is an extreme situation, but one we should be prepared for. Staying calm, surfacing, staying away from the seabed and rocks, protecting yourself, and staying connected to your diving partner are keys to responding to an earthquake. Remember, safety always comes first, and hopefully the above guidelines and advice will help you better prepare for an earthquake while diving. I wish you a safe and sound diving trip!
