The thing about such situations and their mathematical models is that they may include one or more positive feedback loops.
An everyday example, when someone using a sound amplifer and places a micrphone near a loudspeaker and there is that howl as a tiny noise is amplified then get amplified, then the ampified sound is amplified and so on and very quickly the howl screeches out.
Sometimes heard on a television or radio phone-in programme when the caller has not turned the sound off on the television or radio in his or her home while on the call.
