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.
