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]

Quetta Bond
Quetta Bond is a technique developed after the Quetta earthquake, used in brick and other masonry buildings, where vertical reinforcement is used to improve horizontal and vertical bond between walls (see image)[2]. "The Quetta Bond is simply a slight variant of [the brick laying technique] 1½ Flemish Bond where the voids are filled with concrete and steel reinforcement bars rather than brick. It was almost certainly invented (if that is the right word) by Royal Engineers. The RE was heavily involved in the aftermath of the Quetta earthquake".[3]
