Which policy type would best cover damage arising specifically from landslides?

Landslides are typically classified as geological events, closely related to the ground movement phenomena associated with earthquakes. An earthquake insurance policy is specifically designed to provide coverage for such seismic activities, which include landslides that may occur as a result of an earthquake triggering ground destabilization.

Homeowners policies generally offer protection for various hazards but may exclude damages specifically related to geological events like landslides. A general liability policy is structured to cover third-party bodily injury and property damage rather than direct property damage due to specific environmental events. A water damage policy is tailored to cover damages caused by water, such as flooding or plumbing failures, and would not address the unique risks associated with landslides.

Thus, the earthquake insurance policy is the most suitable option as it acknowledges the potential for damage resulting from landslide incidents linked to seismic activity.
