Sinkholes may occur in Cebu

THERE is a big possibility that a sinkhole similar to the one that formed in Guatemala City will appear in Cebu, even in urban areas, a geologist said yesterday.

The Guatemala City sinkhole caught the attention of people all over the world because of its size, which is reportedly 66 feet across and 100 feet deep.

Al Emil Berador, chief geologist of the Mines and Geosciences Bureau (MGB) Central Visayas, said sinkholes can appear in Cebu because a large area of the island is composed of limestone.

Berador said sinkholes are natural formations that occur after limestone deposits gradually corrode when in contact with weak carbonic acid, a combination of water and carbon dioxide.

Carbonic acid can gradually corrode hard limestone, which explains why there are limestone caves, said Berador.

Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by circulating ground water. As the rock dissolves, spaces and caverns develop underground.

These sinkholes can be dramatic because the surface land usually stays intact until there is no longer enough support. Then, the surface area can suddenly collapse.

Berador said majority of the areas in Cebu have limestone deposits.

About 60 to 70 percent of Cebu, including areas that are habitable such as urban areas, is composed of limestone, he said.

waaaaaaaaaah! very alarming!

There is no way to prevent earth from collapsing like what happened in Guatemala, which has lots of cenotes or under water caves. I'm not sure whether Cebu has under water caves otherwise DENR has surveyed the land beneath the city to prove the claim that a sinkhole could occur.
