Wrong again. Read the quote closely and see how it talks about the duration of the collapse, nothing about a specific event - say a large spike from the use of explosives. It can be very reliable for that, though there is not enough information in your quote to prove that.
After all this time, you are still not very good at this.
Seismic sensors basically detect sound waves traveling through the ground. Explosions can create those waves too.
