Besides damage from lava, there are many other hazards that may affect your town and its people. The air may be low quality when the volanco is rupturing from the smoke and ash. When this moves in to town it we pollute the crops which has an effect on the farmers and those who will buy the crops for food. Not only can it hurt crops, but livestock is also hurt if they breath in too much smoke and end up dying. Food can become scarce if crops and animals are not surviving the active volcano.
