I am confused by the conflicting stories. On another thread a poster said there was seismic activity in the area of the mine in the days before the event where miners were trapped. There seems to have been seismic activity after the event that trapped the miners- and now you are saying another earthquake in the area has occurred. I have NO knowledge of this type of thing but to me that points to what the mine owner is claiming. I don’t understand the explanation that the mining incident itself was the seismic event. How does that explain the other seismic activity before and after in the same area?
Another thing I question is when I read about earthquakes or watch a show about them- what keeps coming up is how little even the experts know about the true causes and effects of quakes and aftershocks- there seems to be no real pattern that can lead to further understanding, or predictability of these events. Each event can be very different even in the same area, which is why so little is known. It is hard to study something that is ever changing. With this in mind- how can they know for sure if the mining caused the events or if what is happening is a natural occurance?
What I heard was the motion associated with the seismic event was vertical, which is not typical for an earthquake, but would be consistent with a mine collapse.
