I remember reading a kid's book about Paracutin during elementary school. Just when a geothermal energy plant was going to be built, the eruption stopped. The family where the mountain sprouted without warning still lives nearby last I knew.
Loved the long video. Church looked just like the picture in 1944. Either the video was very old or the narrator got his years wrong. Interesting to see the inside of the church is still being used for religious purposes.
