The mystery boom in the wee hours Saturday was a literally moving experience for Bryan Adlam.

"I heard the boom - it was quite loud - but I also felt it. I felt my house move," said the real estate agent, who lives in the Crown Point neighbourhood near the escarpment.

Turns out bewildered residents across the city heard the same thing after 2 a.m. On the beach strip. The Mountain. Even Ancaster.

Adlam posted a question about the sound blast on Facebook that quickly spawned 500-plus comments, theories and, obviously, fart jokes.

But so far, the source of the thunderous bang remains a mystery.

Was it a supersonic jet? An industrial accident? A skyquake? Nobody seems to know.


Residents concerned after they hear, feel loud boom in Lehigh County, Pennsylvania

People living in the New Tripoli area of Lehigh County want to know what caused an explosion Tuesday morning.

They say they heard or felt a blast, but authorities say they can't determine a cause.

Micki Tapper says she was awake at 7:30 a.m. That's when she heard it.

"There was just a really loud boom. My house shook, my windows shook," Tapper said.

The sound is picked up by her security camera microphone. You can hear a noise, but you can't discern much about it, or how far away it was.

Still, it was alarming. Tapper says she went outside to look around her home because she thought a tree fell on her house.

Comment: You can hear the booming sound starting at :25 in WTMZ's video coverage.

On June 22nd at 21:25 UT, a small asteroid entered Earth's atmosphere and exploded in broad daylight south of Puerto Rico. Airwaves recorded by the Comprehensive Nuclear Test Ban Treaty Organization's infrasound station in Bermuda pegged the blast energy between 3 and 5 kilotons of TNT-a fraction of a WW II atomic bomb. The explosion was clearly visible in images from NOAA's GOES-16 weather satellite:

Meteor expert Peter Brown of the University of Western Ontario says the infrasound signal is consistent with a "small multi-meter sized near-Earth asteroid." According to data compiled by NASA's Center for Near Earth Object Studies, asteroids of this size and energy hit Earth's atmosphere about once a year. That means it's rare-but not exceptionally so.

This bright meteor overflew Toledo and Madrid on 2019 June 15 at 3:48 local time (equivalent to 1:48 universal time). It was generated by a rock from an asteroid that hit the atmosphere at about 80,000 km/h. It began over the province of Toledo at an altitude of about 86 km, and ended at a height of around 39 km over Madrid.

The event was recorded in the framework of the SMART project (University of Huelva), operated by the Southwestern Europe Meteor Network (SWEMN), from the meteor-observing stations located at La Hita (Toledo), and Sevilla.
