damaged by volcanic eruption
A natural volcanic event damages or destroys a structure through lava, ash, hot water, or other volcanic effects.
A structure is damaged by a volcanic eruption when a natural geologic event damages or destroys the structure with lava, ash, hot water, or other volcanic effects.
The damage can be caused by ash or hot water without lava reaching the structure. Other effects are included when they originate in the volcanic event and damage the object.
The event describes damage to the structure, not merely a volcanic eruption in the region. Partial damage qualifies alongside complete destruction.
