The USGS initially measured 5.7 on the Richter scale, but changed its magnitude to 5.9 a few hours later. It adjusted the depth from 20.8 kilometers (12.9 miles) to 9 kilometers (5.6 miles).
The Balochistan Lewis Force, the province’s paramilitary law enforcement agency, said some houses in Harnai had collapsed following the quake.
„The rescue operation has been going on since 3 am. The injured were airlifted to the hospital by helicopter,“ Hornai district commissioner Sohail Afridi said, adding that the situation was now under control.
The Haiti Foundation, a welfare organization, told CNN that Hernai is located in a rural area and is not easily accessible.
