Cost push inflation is caused by an increase in the cost of producing goods and services, which is passed on to consumers, who then pay more. This can be seen through the use of an AD/AS graph... When production costs rise due to increasing petrol costs, rising wages, and natural disasters, aggregate supply will decrease from AS1 to AS2. Producers can't afford to produce as much output, causing a shortage and passing on higher prices to consumers. The general level of prices will rise from PL1 to PL2. This is cost push inflation.
