50 Meters Deep Hole Appears In Bangkok, What Causes Sinkhole?

YOGYAKARTA The appearance of a large hole in Bangkok has caught the attention of the world. The large hole appeared in front of Vajira Hospital in Dusit District, the capital of Thailand, on Wednesday, September 24, morning.

The phenomenon of the appearance of a hole called a sinkhole is quite a cause for panic. Because the sinkhole is 50 meters deep. Apart from this incident, what are the real causes of the singhole?

People know what a sinkhole is, a big hole formed because the soil or rock beneath the earth's surface has collapsed. This condition then triggers the creation of a large hole on the ground surface.

Sinkhole holes can be formed with varying depth and diameter, depending on how much soil and rock subside. Usually the depth varies, but in some cases there can be hundreds of meters. There are even sinkholes filled with water to form a new small lake.

The cause of the sinkhole can be triggered due to geological factors or due to human activity. Here are some of the triggers, reported by Antara.

laps and solubility of rocks are very likely to cause large holes on the earth's surface. Logging can occur in limestone and gypsum rocks because water contains carbonic acid. Usually, the weathering process occurs over a long period of time to form an underground cavity. If the cavity is unable to support the load, then the soil will subside.

Human activities, especially those related to development, can trigger sinkholes. In addition, other activities such as drilling or mining can disrupt soil stability. Overdamped water pumping can also lower the soil surface to trigger sinkholes.

Pressure that is too heavy above ground level can also trigger subsidence. This pressure can be sourced from buildings, heavy equipment, or other constructions. This risk will increase in less stable soil areas.

Another sinkhole trigger is erosion due to water, especially in areas with limestone. When it rains, water will seep into the ground and enter the limestone rock gap. The absorption is able to dissolve minerals and form an underground cavity. If the cavity is getting bigger and more fragile, the subsidence ground cannot be avoided.

Natural disasters such as earthquakes or floods can also disrupt soil stability. The earthquake can trigger the ground to shift to make a cavity underground. Meanwhile, flooding can erode minerals underground.
