Why Is This Black-Sand Beach In Iceland So Dangerous?
Beaches are places of intrigue and sometimes mystery. It is perhaps that mystery and intrigue that makes them such desirable places to visit. Reynisfjara beach is no different, and the reason behind its black sand is actually a fascinating and scientific story.
As the National Oceanic and Atmospheric Administration explains, sand is ubiquitous, existing in many places. It is mainly created from deteriorated rocks, which have broken down from erosion and weathering elements. This process is very long, taking thousands, sometimes millions, of years. Sand becomes beaches and the ocean floor from eroding rocks that make their way there from sources like rivers carrying them to the sea. Waves also have a big part in accelerating the erosion process.
Of course, the difference between regular sand and Reynisfjara sand is the striking black color. As The Travel explains, this hue is actually caused from volcanic activity. Lava from an erupting volcano cooled and hardened in the Atlantic Ocean, creating deep black colors. This hardened lava was eroded by the ocean's currents and waves, giving it its unique texture and look.
