After the Farm event, gages measuring horizontal accelerations at the bottom of Well J-11 began resonating at about 3 to 5 hertz on each shot. This investigation of possible causes concludes that the material surrounding the well casing has fallen away, allowing the casing to move freely in horizontal directions and causing the undesirable resonance
