Conclusion

"In the afternoon I joined my wife and son, who were watching the sheep, and asked if anything new had occurred, since for two weeks we had felt strong tremors in the region. Paula replied, "Yes", that she had heard noise and thunder underground. Scarcely had she finished speaking when I, myself, heard a noise, like thunder during a rainstorm. I could not explain it, for the sky above was clear and the day was so peaceful."

This is a part of a description written by Dominic Pulido, a Tarascan Indian farmer in central Mexico. In 1943 a cornfield in his land suddenly started to erupt ash and gases. In a few weeks it was a volcano over 400 m tall that was later named Paricutin. The photo to the left is of the volcano a few weeks after it started in the cornfield.
