Goddess of the Volcano

A group of space colonists is trapped inside an impossible giant planet, they all go mad from ratiation, and grow to the size of giants.

The blurb reads: "What weird power enabled this planet not only to gain control of a space ship but to plunge the passengers into madness?"

Not a volcano nor a goddess in sight. was the wrong story applied to the cover and title? No other volcanoes in this issue that I could see.
