Sinkholes are not uncommon in limestone and much of KL is built on limestone, but apparently these 3 sinkholes occured in the Kenny Hill formation, which occurs over a large part of the city.
“This is quartzite and phyllite — very strong, hard rocks that have weathered over hundreds of million years."
The holes are thought to have been due to fast flowing water.
