In 2018, German tourist Christine Gaebel died while diving the Great Blue Hole off Belize’s coast. The site plunges over 125 m (410 ft) with steep walls and strong currents, demanding advanced technical skills.
During her descent, a breathing‑apparatus malfunction caused rapid air loss. Despite an emergency ascent attempt, she succumbed to hypoxia. Her body was recovered by fellow divers.
The Blue Hole remains a world‑class dive destination, but only for properly certified and equipped divers.
