Eid-ul-Fitr in coastal Karnataka on June 15, rest of Karnataka on June 16

Bengaluru, May 20: A mysterious "boom" heard in large parts of Bengaluru this afternoon left residents of the city and social media users puzzled. While the source of the sound is being investigated, the Indian Air Force (IAF) indicated that it could be the result of "routine test flights that necessitate going supersonic a times".

The sound was heard from as far as the Bengaluru airport in Devanahalli to the IT hub of Electronic City 54 km away. It was also heard in Kalyan Nagar in east Bengaluru, central Bengaluru's MG Road and areas such as Marathahalli, Whitefield, Sarjapur and Hebbagodi.

IAF said no aircraft of training command was flying in the area. "However, ASTE (Aircraft and Systems Testing Establishment) and HAL (Hindustan Aeronautics Limited) could have been undertaking their routine test flying, which necessitates going supersonic at times. These are done well beyond the city limits in specified sectors. However, considering the atmospheric conditions and reduced noise levels in the city during these times, the aircraft sound may become clearly audible even if it happened way out from the city," said the air force statement.

Many people had speculated that the sound could have been caused by a fighter jet such as a Mirage 2000.

"We have also asked the Air Force Control Room to check if it was a jet or supersonic sound. Bengaluru police are awaiting confirmation from the Air Force," Bengaluru police commissioner Bhaskar Rao said in a statement.

It was not an earthquake, Karnataka's state disaster monitoring centre had tweeted earlier.

"Earthquake activity will not be restricted to one area and will be widespread. We have checked our sensors and there is no earthquake activity recorded today," the Karnataka State Natural Disaster Monitoring Centre said, quoting its director Srinivas Reddy.

"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," the agency tweeted.

#Bangalore and #BangaloreBoom was among the top trends on Twitter this afternoon.

"We are trying to ascertain the source of the noise," a senior police officer said. "In Whitefield area, we have searched on the ground and so far, there is no damage to any property," he added. There were no calls to the police control room reporting any damage.

Bengaluru, Jun 5: An earthquake of magnitude 4.0 on the Richter Scale jolted Karnataka on Friday morning while another with a magnitude of 4.7 was felt in Jharkhand.

The tremors were felt in Hampi (Karnataka) and Jamshedpur (Jharkhand), according to the National Center for Seismology (NCS).

According to NCS, the aftershocks were felt at 6:55 am in both the places today.

Mangaluru, June 10: The first direct repatriation flight from Damma to Mangaluru International Airport under Vande Bharat Mission will be operated on June 21.

Thousands of people from coastal districts of Karnataka are stranded without flights in different parts of Saudi Arabia after the announcement of covid lockdown in March this year. 

Even though the government of India launched Vande Bharat Mission to repatriate Indian expatriate through special flights, no flight was scheduled from Saudi Arabia to Mangaluru.

Several organisations had exerted pressure on the government of India and government of Karnataka to bring back stranded Kannadigas from Saudi Arabia.  

With the sole intention of helping the stranded Kannadigas, a few philanthropists in Saudi Arabia last month formed an NGO called Saudi Kannadigas Humanity Forum under the leadership of Zakariya Bajpe and Sheikh Expertise.
