The Quetta earthquake happened on 31 May 1935 and measured 7.7 on the Richter scale. An estimated 30,000 to 60,000 people died.

Two large earthquakes had occurred in the area between the Bolan Pass and Quetta in 1931. The first of these near Sharigh Mw 6.8 24 August 1931, was followed by the Mach Mw 7.3 earthquake 27 August 1931. Circumstantial evidence suggest that resulting conditions were eventually responsible for triggering the Quetta earthquake.[1]
