What it might have been
These are the usual explanations around here, and how to tell them apart.
Military training
Artillery, demolition and live-fire training carries a long way across open ground, especially from the Yakima Training Center to the west.
Sonic boom
An aircraft going supersonic produces a sharp double crack that arrives with no warning.
Transformer or electrical fault
A failing transformer or line fault makes a single hard bang, often with a flash and a local power cut.
Quarry or construction blasting
Permitted blasting produces a muffled thump and ground shake that arrives before the sound.
Fireworks
Large shells make a sharp report with an echo, usually in bursts and usually after dark.
Earthquake
A shallow local quake can produce an audible boom along with the shake.
