Disaster, tragedy, catastrophe, and calamity all name serious harmful events. Disaster is the most common, neutral word. Tragedy stresses sadness and human loss, not necessarily large damage. Catastrophe is stronger, suggesting extreme scale affecting many people. Calamity is formal and literary, describing widespread hardship.

这四个词都表示造成巨大破坏或痛苦的严重事件，但语气强弱和使用场合不同：disaster最常见、语气中性；catastrophe语气更强、规模更大；tragedy强调悲伤和人员的不幸，未必涉及大规模破坏；calamity语气正式、书面化，常指持续或普遍的苦难。这里不比较disaster表示“糟糕、失败的事情”的口语用法（如the party was a disaster），也不比较tragedy指“悲剧”这一戏剧体裁的用法。
