Bengaluru, July 2 (TIWN) A mysterious loud sound similar to an explosion was heard across many parts of Bengaluru on Friday noon. Several residents of the city took to Twitter to share that they heard a loud 'thud' sound.

Officials from Karnataka State Natural Disaster Monitoring Centre said their broadband seismograph has not recorded any earthquake. "The seismograph is able to record ground vibrations, even those caused by a quarry, within 10 km distance. From what we hear, the sound doesn't seem to be related to earthquake as no ground vibrations have been recorded," a senior official told DH.  Police, after a preliminary verification, ruled out the possibility of an explosion causing the sound. "We don't have clear information yet. However, going by the past experience, it looks like a sonic boom," an officer of the DCP rank told DH.
