disaster

n. an event, whether natural or man-made, that disrupts normal operations, often inflicting some level of damage to collections

Notes

The term emergency is often used interchangeably with disaster, although emergency usually implies an event smaller than a disaster. Disasters may be natural, including fire, flood, and earthquakes, or they may be man-made, including HVAC failure, theft, malicious destruction, error, cyberattack, and war.
