The 1935 Quetta earthquake (Urdu: بلوچستان زلزلہ‎) occurred on 31 May between 2:33 am and 3:40 am at Quetta, Balochistan, British Raj (now part of Pakistan). The earthquake had a magnitude of 7.7 Mw^[2] and anywhere between 30,000 and 60,000 people died from the impact. This ranked as the deadliest earthquake that hit South Asia until the 2005 Kashmir earthquake.^[2] The quake was centred 4.0 kilometres south-west of Ali Jaan, Balochistan, British India.^[2]

Earthquake

Quetta and its neighbouring towns lie in the most active seismic region of Pakistan atop the Chaman and Chiltan faults. Movement on the Chaman Fault^[3] resulted in an earthquake early in the morning on 31 May 1935 estimated anywhere between the hours of 2:33 am^[2] and 3:40 am^[4] 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 MW and previous estimates of 8.1 MW 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 MW occurring on 2 June 1935.^[2] The aftershock, however, did not cause any damage in Quetta, but the towns of Mastung, Maguchar and Kalat were seriously affected.^[2]

The Chappar Rift in Balochistan, a landmark railway site, was affected by the 1935 earthquake, when the mountains opened up in parts. The gorges and rifts owe much to this earthquake for their appearance.

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.^[4] 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.

From memorabilia of a member of the Royal Signals in 1935:
"For long-distance military work, we used large rhombic set-ups, with heights of 50 to 75 feet. For amateur work a single-wire horizontal, with the feed at three-sevenths of the total length, was used. As a matter of interest, during the Quetta earthquake of 1935, all civilian radio nets were destroyed, and all traffic was taken over by R.Signals stations. We did over 168 hours of frantic communications from D.I.K. to Quetta; sleeping on the floor next to the equipment."

Bruce Street immediately after the earthquake lay desolate in ruin. Commercial businesses came to a halt along with the complete destruction of the Kabari Market and the Fruit Market.

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 damages. It was reported that only 6 out of the 27 machines worked after the initial seismic activity.^[4] A Regimental Journal for the 1st Battalion of the Queen's Royal Regiment based in Quetta issued on 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.^[4]

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.^[4] While assisting in rescue efforts, Lance-Sergeant Alfred Lungley of the 24th Mountain Brigade earned the Empire Gallantry Medal for highest gallantry.^[5]

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.^[4] 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.^[4]

Initial medical set ups were established near the railway station to help provide first aid to the survivors. A tent city was built in the vicinity.

Opera Talkies, a cinema set up for the recreation of the soldiers, was destroyed in the quake.

Significance

The natural disaster ranks as the 23rd most deadly earthquake worldwide to date. In the aftermath of the 2005 Kashmir earthquake, the Director General for the Meteorological Department at Islamabad, Chaudhry Qamaruzaman, cited the earthquake as being amongst the four deadliest earthquakes the South Asian region has seen; the others being the Kashmir earthquake in 2005, Pasni, 1945 Balochistan earthquake, in 1945 and Kangra earthquake in 1905.
