Buzzfeed has done an analysis of the damage done when Superman and Zod go toe-to-toe. Kinda spoilerish, a little bit.

"In a study done exclusively for BuzzFeed, scientist and longtime disaster expert Charles Watson worked with his team at Watson Technical Consulting to model and anticipate the damage done to Metropolis, both in the form of human casualties and monetary cost. They ran analyses of the World Engine ground zero in Central Manhattan and central Chicago, finding that the major damage would be a mile in diameter."
