Almost like an explosion?

I won't go so far as saying it was a nuke although one could make that assumption.
Check out article, and comments.
Thanks, WildHighlander57. Would have missed this without your ping.

It was a quake for goodness sake. variations in seismograph patterns are a function of multiple influences - proximity, depth of quake, wave arrival times, etc.
I lived in socal for a loooong time and saw many seismographs of whatever quake had happened ....
that pic of the Nevada event does NOT look normal.
A normal seismograph shows the quake start gradually increasing, reaches its maximum, then gradually decreasing.
The seismograph in the pic of this event in Nevada reaches its maximum right away, then goes for awhile, then decreases.
Also, having been through various sizes of quakes, one feels it coming on gradually, then it gets up to its maximum, then gradually decreases.
