011. Danger of Being Swept by Waves
Waves tend to rise sharply where water meets the rocks. The shallower the depth and the higher the wave, the greater the danger.
When a wave strikes the rocks, a reflected wave spreads backward, forcefully pushing the angler away. The force of a reflected wave tends to grow sharply as wave height increases.
Prevention: check the Korea Meteorological Administration marine forecast for wave height before heading out, and only approach when wave height is 1 m or less. In a sudden situation, drop your body into the water immediately and brace yourself against the rock to maintain balance.
- Underestimating wave height Entering the water can cause a sudden shock and a fall
- If you are pushed backward without touching the rock, you can be swept and injured
022. Slip‑Induced Falls on Wet Rocks
Rocky shores become slippery as the tide rises, leaving fine shells and seaweed on the surface. Friction drops sharply once the surface gets wet, making it very slippery.
When currents run strong, the risk of slipping and falling backward increases significantly. If your center of gravity is ahead of the rock edge, you may rotate and fall into the water.
The recommended response is to wear shoes with rubber soles or spikes and to keep a triangular stance by holding the rock with your hands. Also, consult the tide table and avoid times when the tide changes rapidly.
033. Hazard of Being Caught in Rapid Currents
Around rocky shores, currents and wind can quickly form rapid flows, and getting caught in one can pull a person into deep water within moments.
The stronger a rapid current runs, the more forcefully it wraps around and pulls the whole body. This force wraps around the body and pulls, so an immediate anchor point is essential.
Prevention: before heading out, check the latest marine safety information from the Korea Coast Guard and KMA, and minimize approach based on wind direction (southeast or northwest winds) and current strength.
044. Injuries and Infections from Rock Fragments
When waves hit rocks, tiny fragments become suspended in the water. These fragments average 0.5–2 mm in diameter and are sharp enough to pierce skin, raising the risk of bacterial infection.
Marine bacteria can cause inflammation if the wound stays in water for an extended period, and delayed treatment may lead to tissue damage.
The response is to trim fingernails and toenails, keep a waterproof band and antiseptic ready, disinfect any wound immediately, and protect it with a pressure bandage. If you stay in water for a long time, rinse thoroughly and dry the area to prevent infection.
