MANILA, Philippines 鈥� The Metro Manila Development Authority (MMDA) has advised motorists to take alternative routes and avoid a sinkhole that formed in the middle of Sales Road near the Villamor Air Base in Pasay City.

The MMDA has yet to indicate what caused the hole, but according to the US Geological Survey (USGS), sinkholes happen due to 鈥渄issolution of soluble rocks such as limestone, dolomite, and gypsum 鈥� when acidic water from rain and groundwater interacts with these rocks.鈥�
USGS also said sinkholes may occur from human activities such as extensive groundwater pumping.
