Bengaluru loud boom: What we know so far
Not an earthquake
Even as the incident create flutter about the noise being an earthquake, scientists from Karnataka State Natural Disaster Management Center (KSNDMC) confirmed that the loud sound was not related to an earthquake. A scientific officer working with the Karnataka State Natural Disaster Monitoring Centre told India TV that the sound was not due to any seismic movements. "We have monitored the seismometers in the area and everything seems fine. Therefore we can say affirmatively that the sound was not due to an earthquake," Jagdish said.
Not a sonic boom
Some thought that the sound was a sonic boom. However, it was not. A sonic boom is a sound linked with the shock wave that is produced by an aircraft or other object flying faster than the speed of sound. It produces enormous amounts of sound energy and sounds like an explosion or thunderclap.
Likely a cyclonic effect
Natural disaster team told India TV that the sound is likely an effect of a heavy vacuum created and sudden entry of cyclonic wind, created by Amphan between hot and cold air which had happened last year as well.
