Amid lockdown, people in Bangalore on Wednesday afternoon were caught panic-stricken.

A thunderous sound was heard in many areas on Wednesday afternoon in Bangalore.

People felt their windowpanes rattling for more than five seconds.

People initially thought it was an earthquake.

Quickly, some residents took to Twitter, wondering if an earthquake had hit the tech-capital of India.

However, Srinivas Reddy, director, Karnataka State Natural Disaster Monitoring Centre confirmed that it was not an earthquake.

Speculations were rife among the Twitterati that the ‘sonic boom’-like sound was due to a fighter jet.
