Explanation:

The aggregate supply curve shows the total quantity of products and services supplied at a given price, over time. Changes in the quantities demanded affects the aggregates supply only in the short-run.  In the long-run, only technological changes, capital, and labor impacts the aggregate supply curve.

The aggregate supply curve shifts to the left if the production decreases. It will shift to the right when production rises. A natural disaster can  significantly reduces production in the economy. A disaster can destroy a country's manufacturing infrastructure, including factories, power distribution,  transport networks, and material sources. The effects will reduce the overall production and supply of goods and services for a long period.
