12 Views What makes volcanoes erupt?
In February of 1942, Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield. However, the sound wasn't coming from the sky.

Where do new volcanoes like this come from, and what triggers their unpredictable eruption? Steven Anderson investigates.
