Let's do some math and science. (something that kooktards can't understand)

The North Tower was 1368' tall and produced a 2.3 magnitude signal.

The center of mass of a uniform rectangular block would be half that,
however the towers were much stronger (and heavier) near their bottoms, to
support the upper floors.  Let's call the center of mass to be at just
1/3 height, or 456 feet instead.  After the collapse, the mass was in its
basement levels, from 70 feet below street level up to street level.  The
center of mass of that would be half that, or 35 feet below street level.  
Total collapse distance of center of mass=456'+35'=491', 149.657 meters,
almost 150 meters.

Mass of each tower = 500,000 tons, or 453,592,370 kg.  

Potential gravitational energy released E = mgh.
E = 453592370 * 9.81 * 149.657 = 665,934,911,240 joules or 666 billion 
joules.

http://www.convertalot.com/earthquake_power__calculator.html calculates a
2.3 magnitude quake as 178 million joules.  This means 0.027% of the
collapse energy became seismic energy of 2.3 magnitude.  That seems rather
too low to me, but this was not a simple drop. Much of that energy went
into smashing floors and columns apart, smashing concrete to dust, lots of
noise and so forth.  How "efficient" should a large mass dropped on 
bedrock be at converting its kinetic energy to an earthquake signal?
