Thunder, as a pressurized sound wave, can hurt your ears, scare children and animals, and set off some car alarms.
Since it is caused by the rapid heating of air produced by a nearby lightning strike, it can also alert you that it is no longer safe to be outdoors: if you're close enough to hear thunder, you're close enough to be at risk.
