Initial data
In recent years, many residents of anchorage, I hear a strange noise in the early morning hours. A loud noise comes a distant rumble, getting louder, and then disappears.
Anchorage is the largest city in Alaska, located in the South Central part of the state on the shores of cook inlet.
People many kilometers away from each other report that a strange sound abruptly wakes them up, sometimes one or even several times within a few hours. But no one knows what causes this mysterious metallic groan.
Last time it was heard around 5 a.m. Monday. This alarm woke up the residents from the town centre to the West of anchorage.
He was described as eerie, symphonic and also sporadic, sounding for about 20 seconds and then disappears. Is the sound loud internally. You feel the sound.
“It's almost like a siren in the mist and the screech of metal on metal. It's kind of like a submarine scraping the bottom or something,” – said the witness.
Another witness describes the crash as “underwater moan.”

I'm a sound engineer and specializers on audio forensics. I isolated and purified the audio from a video that was heard in anchorage at 5 a.m. on 8 February 2020. I have my own ideas about the source, but here you should speculate. Sounds six times, and the image shows how the computer analyzed the harmonic content. Note the high - G and low C #. This interval - the Tritone, also known as "Interval of the Devil", mostly because of the eeriness that it evokes.

What do you think it is?

Hypotheses
The signal strip
Rattling strip, also known as warning strips, Audible lines, Growling lines - are the device for road safety by alerting inattentive drivers of potential danger by causing a tactile vibration and audible rumbling, transmitted through the wheels into the vehicle interior.
Rumbling strip is applied along the direction of movement following a line edge or centerline to alert drivers when they leave their lanes. Rumbling strips can also be installed in a series across the direction of travel, to warn drivers about stopping or slowing traffic ahead or approaching a dangerous place.
Investigation
In addition to the sounds from the signal lanes of the highway, it may be, for example, sounds from the train tracks, ships, and airplanes.
