IMO Actually quarry blasting does register on earth quake meter. Usually around 2.0 in the area? The shock wave can cause ground shake and increase collapse over time if the underground structure is weak. Now with construction above and weight of retention Pond and leaks over time ground collapse’s could happen. So, time will tell if sinkhole problems will pop up in newly construction area.
IMO about every sinkhole in the villages can be traced to retention pond leaks, water drain pipes leaks, residential drainage problem, or just weak ground structure aggregated by years of ground water leakage.
Is this something to worry about? IMO 2 out of 10 on the worry meter. I also think it has no impact on purchasing house in that area. But, if you don’t like to be close to active quarry then don’t buy close and if you do don’t complain about after the fact.
All of this in my opinion of course.
