Summary: A fanatical Native American scientist demands the return of Manhattan Island to his people or he will unleash artificially created earthquakes upon the city! While at first his claims are dismissed as the ravings of a madman, he soon proves them entirely founded when, after capturing Lois Lane, he unleashes a terrifying series of electric earthquakes upon the city. It looks like a job for Superman...only how can Superman stop the source of these artificially induced earthquakes and still save Lois, now trapped in our villain's underwater lair which has begun filling with water due to Superman attempts to stop the earthquake device! Here we have yet another fast-paced, exciting storyline. The underwater lair and its mechanical devices have a decidedly futuristic look and make for some arresting visuals, although one does wonder why our scientific genius/lead villain travels via a rather ordinary speedboat?
