Blizzards do not affect any part of earth below the crust and have little or no impact on the surface crust, but they do impact the people, involving mass damage to people and cause sicknesses from the cold and people do end up dying due to blizzards by not being able to get out fast enough or their house caved in due to how much snow has fallen. It could cause damage to property like cars and houses, also due to the high winds the electricity might short circuit which means the power will go out. It could also knock down trees which might fall into houses or block the streets.
