The red marker is our best guess at the source; the blue dots are where people were. This combines two independent clues: the 7 directions people pointed, and how loud it was where each person stood (a boom is loudest nearest its source). The marker sits where those two agree - which is why it's more trustworthy than either alone. Adding more directions or loudness reports sharpens it.
What it lines up with
Automatic cross-references. Suggestive, not proof.
Thayer Drive Substation (substation) - about 0.8 km from the estimated origin.
A USGS M1.21 earthquake 72 km away, 13h apart.
Conditions weren’t especially sound-carrying. (22°C, wind 6 km/h, 51% cloud)
overnight on a weekend.
Waxing crescent (26% lit).
Transformer and substation faults set off both a boom and an outage. See who else nearby is out, and when it is coming back.
