An unprecedented loud thundering noise created a storm of worries in Bengaluru yesterday. Bengaluru residents in locations like International Airport, Kalyan Nagar, MG road, Marathahalli, Whitefield, Sarjapur, Electronic city, to name a few, heard a loud sound on May 20 which raised fear of an earthquake.
Officials tried to find out the real reason for the loud sounds and it was soon revealed that there was actually no earthquake instead it was a sonic boom sound. The loud sound came from the routine IAF Test Flight with a supersonic profile.
As the supersonic object moves, this conical region also moves behind it and when the cone passes over the observer, only then will they briefly experience the sonic boom sound.

The Whitefield Police made investigations into the incident after observing the explosion-like sounds in many parts of the city. Many people were assuming that the thundering sounds came from an explosion or an earthquake. Meanwhile, the Karnataka State Natural Disaster Management Center (KSNDMC) confirmed that activity reported was not an earthquake.
The Defence Ministry stated that it was routine IAF Test Flight with a supersonic profile and ruled out the possibility of it being an earthquake. The Defence Ministry tweeted saying that it was a routine IAF Test Flight which started from Bengaluru Airport and flew in the allotted airspace outside the city limits.
The aircraft belonged to the Aircraft Systems and Testing Establishment whose test pilots and flight test engineers test out the aeroplanes. He elaborated that the sonic boom was heard while the aircraft was decelerating from supersonic to subsonic speed.

The activity reported in Bengaluru is not due to an Earthquake. The Seismometers did not capture any Ground Vibration as generally happens during a mild Tremor. The activity is purely a loud unknown noise.— KSNDMC (@KarnatakaSNDMC) May 20, 2020
