BENGALURU: Residents of tech city, Bangalore heard a rattling supersonic sound. It sparked the rumours of an earthquake, a fighter plane travelling at a high speed and even an explosion, as per an official on Wednesday, May 20.
A representative from the state-based NDMA (Natural Disaster Management Authority) reported, "n 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."
The earthquake rumours were out of the picture as soon as a spokesperson from Karnataka State Natural Disaster Management Committee revealed that the seismometers were not able to capture any kind of ground vibrations that happen during an earthquake during the time when the unusual sound occurred.
In a short press note, it was mentioned, "The activity is a loud unknown noise."
An official from the NDMA ascribed it to the same effect a heavy vacuum creates as a sudden entry of a cyclonic wind occurs between hot air and cold air, as it happened a year ago.
The official further clarified, "The explosive sound is not because of a quake in the city and no need to panic."
An official from Bangalore's fire brigade department also revealed that the anonymous sound could be because a mining blast which was made for rocks during underground construction.
