Without more specific information, my guess would be just that, a guess.
However, I will go on record saying that the seismic signature I noticed from both those station is HIGHLY unusual, and I cannot find a seismic action
that would provide that kind of signature. I believe it to be artificial in nature, and if it is in fact artificial, it would be of extremely large
scale to register on a seismograph, especially on two of them separated by that distance...
Read into that what you will.
