Supervolcano

Only a small number of Supervolcanos exist across our planet, but have the potential to prove catastrophic for mankind if ever to erupt. You have been contracted by the government to tackle the Supervolcano threat. Establish your operation and harvest super heated steam from deep inside the volcano. Balance the challenges of building a heat network and growing local populations, whilst keeping the magma chamber pressure under control. Fail to meet your quota and the resulting eruptions and quakes will see those precious populations disappear! —description from the designer
