Colaba records wind speed of 102 km/hr from Taukate, lets see historic Mumbai wind speeds from Cyclones

Bangalore sound is more likely to be caused by Sonic boom from a Bolide or also called detonating fireballs. We can name it “Bangalore Quarantine Boom”

Ps: I am neither an expert in weather nor in Astronomy, this report is compiled based on request and interest. And this is more likely the cause of the noise, if all others are ruled out. Based on an incident in Tiruppur which a reporter inquired few months, have gone through the reasons then and today to I can conclude that Bangalore Quarantine Boom is more likely to have been caused by a Bolide. Since IAF has told that none if their flights were flying at that time, this may be the reason. Again only if IAF is ruled out this comes into force.

The IAU has no official definition of “bolide”, and generally considers the term synonymous with “fireball”. Astronomers often use “bolide” to identify an exceptionally bright fireball, particularly one that explodes. They are sometimes called detonating fireballs.

What is Sonic Boom?

The sound released from the fireball is called a sonic boom. Sonic booms are caused by an object traveling faster than the speed of sound (about 767 mph at sea level). Because of their speed, they emit sound in an unusual way. Rather than producing sound waves in a spherical way like the ones that are created when a pebble is tossed into a pool of water, an object moving faster than the speed of sound emits waves in a cone-like pattern. It’s similar to the wake of a fast motorboat as water is pushed to either side.

When that cone of waves passes over an observer, they hear a sharp report, like a very loud and brief explosion. Since objects from space can hit the atmosphere at speeds of over 25,000 mph, which is far faster than the speed of sound, sonic booms are inevitable.

One can read this news and compare the relvance to today’s blast, atleast one guy there caught the sonic boom there, namma oorula who will record these.

Kerala 2015 Fireball

The fireball, reportedly accompanied by a sonic boom, was noticed across the sky in parts of Thrissur, Ernakulam, Palakkad, Kozhikode and Malappuram districts of Kerala at around 22:00 PM IST. The sighting of suspected fireball-like phenomenon, reportedly accompanied by booming sound in some cases, triggered panic across the Cochin in 2015.

Why then no bright light like 2015 in Bangalore

2015 event happened in night while today’s event in Bangalore was on daytime, it may not possible to see the brightness in the day time. While fragments reached the surface in Kerala 2015, this time in Bangalore events the fragments may not have reached the earth surface.

2019 in Tiruppur

I can remember a Vikatan reporter even speaking with me for days on a similar event in Tiruppur district in the end of 2019 or early Jan, where people heard a massive blast but there was no blast observed at the ground. The report never came in news in the end. Anyone from Tiruppur who heard this noise last year-end, can please provide their views.
