“An inquiry has been ordered to ascertain the cause of a super-sonic sound in the city this afternoon (around 1.30 p.m.) after it set off panic and rumours of a quake or explosion due to mining blast,” he said.

According to initial investigation, the loud noise that sounded like a crash was heard across the city from around 1:20 PM. The NDMA said that the sound can be attributed to the like effect of a heavy vacuum caused by sudden entry of cyclonic wind between hot and cold air, something that has happened a year ago.

Interestingly, the sound was heard around the same time when Cyclone Amphan was closing in to begin its landfall in the coastal regions of Odisha and West Bengal.

Meanwhile, a city fire brigade official told IANS that the massive boom could also be due to mining blast of rocks for underground construction.
