huge bursts of energy
...........................................................
massive underground explosions
...........................................................
The Palisades seismic data recorded a 2.1 magnitude earthquake during the 10-second collapse of the South Tower at 9:59:04 and a 2.3 quake during the 8-second collapse of the North Tower at 10:28:31.

However, the Palisades seismic record shows that - as the collapses began - a huge seismic "spike" marked the moment the greatest energy went into the ground. The strongest jolts were all registered at the beginning of the collapses, well before the falling debris struck the Earth.

These unexplained "spikes" in the seismic data lend credence to the theory that massive explosions at the base of the towers caused the collapses.

A "sharp spike of short duration" is how seismologist Thorne Lay of University of California at Santa Cruz told AFP an underground nuclear explosion appears on a seismograph.

The two unexplained spikes are more than 20 times the amplitude of the other seismic waves associated with the collapses and occurred in the East-West seismic recording as the buildings began to fall.

"a small explosion"
I think not.

If it was THAT big, other stations would also pick it. If they didn't, that's another mystery.

Also, if only one station did pick it up, they cannot state where the explosion was. They cannot accurately determine range. And they cannot determine direction at all. The location of the epicenter of a quake is determined by combining range estimates of multiple spatially separated stations.
