Insurers use the term "Act of God" to describe natural events that humans cannot affect, such as earthquakes, floods, cyclones, or lightning. Most comprehensive insurance policies, especially those for homes or vehicles, cover Acts of God. However, this does not mean every catastrophe is covered automatically. Gradual natural deterioration causes damage, such as soil erosion from water over time or slow damage from poor maintenance under heavy rainfall. Unless otherwise specified, events of this nature may not be automatically covered under comprehensive policies. You will often find this term when taking home or travel insurance.
