After a severe tsunami struck Andaman Island at the end of 2004, Michael Reynolds and his team helped out the residences who lost everything including their homes. Michael Reynolds built a low-tech shelter but strong for earthquake and tsunami; the round shape of the shelter can split the force of a tsunami. The shelter is built out of local materials such as used plastic and glass bottles and worn-out tires. The roof is designed to collect rainwater, which can reduce the wells in the future.
