All natural disasters start from bad weather. The materials that are suitable against a volcano eruption are: steel door, chicken wire, aluminum sheets, and concrete walls.
The steel door was to get in and out of the shelter when a natural disaster starts or finishes. This material has been chosen because steel is strong.
The concrete walls are out for the base of the shelter and the roof. This material has been chosen to protect against lava because it provides a strong foundation for an emergency shelter.
The aluminum was used for the inside layer to stop lava from coming in. This material was chosen because aluminum is strong.
The chicken wire was used to hold the shelter together and extra protection against lava.
This material has been chosen to protect against volcanic eruptions because it can give the structure more protection and strength against lava.
Lots of materials can help protect against different types of natural disasters.
