and its neighbouring towns lie in the most active seismic region of Pakistan atop the Chaman and Chiltan faults. Movement on the Chaman Fault resulted in an earthquake early in the morning on 31 May 1935 estimated anywhere between the hours of 2:33 am and 3:40 am which lasted for three minutes with continuous aftershocks. Although there were no instruments good enough to precisely measure the magnitude of the earthquake, modern estimates cite the magnitude as being a minimum of 7.7 and previous estimates of 8.1 are now regarded as an overestimate. The epicentre of the quake was established to be 4-kilometres south-west of the town of Ali Jaan in Balochistan, some 153-kilometres away from Quetta in British India. The earthquake caused destruction in almost all the towns close to Quetta, including the city itself, and tremors were felt as far as Agra, now in India. The largest aftershock was later measured at 5.8 occurring on 2 June 1935. The aftershock, however, did not cause any damage in Quetta, but the towns of Mastung, Maguchar and Kalat were seriously affected.
Casualties
Most of the reported casualties occurred in the city of Quetta. Initial communiqué drafts issued by the government estimated a total of 20,000 people buried under the rubble, 10,000 survivors and 4,000 injured. The city was badly damaged and was immediately prepared to be sealed under the military guard with medical advice. All the villages between Quetta and Kalat were destroyed and the British feared casualties to be of higher numbers in surrounding towns; it was later estimated to be nowhere close to the damage caused in Quetta. Infrastructure was severely damaged. The railway area was destroyed and all the houses were razed to the ground with the exception of the Government House that stood in ruins. A quarter of the Cantonment area was destroyed but military equipment and the Royal Air Force garrison suffered serious damage. It was reported that only 6 out of the 27 machines worked after the initial seismic activity. A Regimental Journal for the 1st Battalion of the Queen's Royal Regiment based in Quetta issued in November 1935 stated,
It is not possible to describe the state of the city when the battalion first saw it. It was razed to the ground. Corpses were lying everywhere in the hot sun and every available vehicle in Quetta was being used for the transportation of injured … Companies were given areas in which to clear the dead and injured. Battalion Headquarters were established at the Residency. Hardly had we commenced our work than we were called upon to supply a party of fifty men, which were later increased to a hundred, to dig graves in the cemetery.
Rescue efforts
Tremendous losses were incurred on the city in the days following the event. On streets, people lay dead, buried beneath the debris, some still alive. British regiments were scattered around town to rescue people, an impossible task as 1st Queen's remember. While assisting in rescue efforts, Lance-SergeantAlfred Lungley of the 24th Mountain Brigade earned the Empire Gallantry Medal for highest gallantry. The weather did not prove to be of much help and the scorching summer heat made matters worse. Bodies of European and Anglo-Indians were recovered and buried in a British cemetery where soldiers had dug trenches. Padres performed the burial service in haste as soldiers would cover the graves quickly. Others were removed in the same way and taken to a nearby shamshāngāht for their remains to be cremated. While the soldiers excavated through the debris for a sign of life, the Government sent the Quetta administration instructions to build a tent city to house the homeless survivors and to provide shelter for their rescuers. A fresh supply of medicated pads was brought forth for the soldiers to wear over their mouths while they dug for bodies in fears of a spread of disease from the dead bodies buried underneath.
As an eight-year-old boy, Yash Pal, now a renowned Indian space scientist and educationist, was trapped under the building remains together with his siblings and was rescued.
