Peril: Volcanic Eruption

The volcanic eruption peril in homeowners insurance covers damage caused directly by volcanic activity, including lava flow, ash, dust, airborne shockwaves, and explosions. It protects the home's structure, personal property, and other insured structures. 

However, coverage typically excludes damage from earthquakes, tremors, or land movement associated with the eruption. Separate earthquake insurance may be needed for those risks.

Most homeowners, renters, and business insurance policies do not cover damage caused by earthquakes, land tremors, landslides, mudflows, or other earth movements, regardless of whether these events are triggered by or result in a volcanic eruption. Earthquake insurance can be purchased separately from private insurers as an endorsement to a homeowners policy or, in California, through the California Earthquake Authority, a privately funded but publicly managed organization.

Damage to land, trees, shrubs, lawns, property in the open, or open sheds (including their contents) is generally not covered under standard policies. Additionally, the cost of removing ash from personal property is typically not covered unless the ash causes direct physical damage to the property first. Removal of ash from surrounding land is also excluded from coverage.

AVERAGE COST PER VOLCANIC ERUPTION CLAIM: 

Unknown due to the rarity

Due to the extremely rare nature of volcanic eruption damage to homes, finding a concrete "average loss amount claimed per home" for damage is nearly impossible.
