Loud Noise Rattles Bengaluru: Was It Thunderstorm or Something Else?

Residents across south and East Bengaluru were awake on Sunday by a loud " firecrackers-like" sound that rang out between 4.30 am to 5:30 a.m. The unexplained noise was reported in several neighborhoods, including Banashankari, Richards Town.

Many startled residents quickly took to social media to express their confusion and share their experiences. On Reddit, a post titled "How are you all sleeping rn? The thunderstorm is violent af this morning. I can't get any sleep whatsoever. I also have an expensive antenna (amateur radio one) begging to take the hit from the lightnings" rapidly gained traction as users weighed in with their own accounts of the event.

One user commented, "Heard the biggest thunder sound ever in my life," while another remarked, "I heard it just now. How did you get it 12 mins ago?"

The sudden noise, which has sparked widespread speculation online, coincided with a thunderstorm in the area. Many residents believe the sound may have been caused by a particularly loud thunderclap.
