1What is a blue hole?

A blue hole is a massive hole on the sea bed. It can be hundreds of feet deep and is identified by its distinctive blue color. Marine life exists only in the upper layers of the hole as oxygen is absent below 330 feet into the hole. Experts believe that blue holes can be used to study climate change based on how water levels have changed over the years.

2The deepest blue hole

The Dragon Hole is located in the South China Sea, about 25 kilometers south of Discovery Reef in the Paracel Islands. It is the deepest known blue hole on Earth, at a depth of an estimated 987 feet. This depth was measured by sending a robot fitted with a depth sensor. According to Chinese legends, this is where the Monkey King discovered his golden cudgel.

3The Great Guatemalan Sinkhole

On May 30, 2010, a massive sinkhole measuring 60 feet wide and 325 feet deep appeared right in the middle of Guatemala City. Chances were high because the city was built on weak materials like volcanic pumice. As the sinkhole developed, it swallowed an entire factory. It was attributed to several factors like the Tropical Storm Agatha, the Pacaya Volcano eruption, limestone and broken underground pipes which leaked water that made the soil soft.

4The Nongle Sinkhole

In 2018, a group of Chinese-British speleologists discovered a massive natural sinkhole in the Limestone Mountains of Nongle in southern China. The sinkhole measures 1,476 feet in depth from the access point on the mountain. It is believed that this was formed due to tectonic shifts and natural limestone being deposited by oceans 250 million years ago.

Scientists climbed down 650 feet into the sinkhole with a single rope. They then discovered two interconnected cave halls. The entrance of the cave measured 00 meters wide and 200 meters long. The deepest point in the cave was 387 feet deep. Therefore, this sinkhole now holds the record for the deepest sinkhole in the world.
