A plane flying horizontally into a building would produce a lesser seismic signature than a plane flying a near vertical dive into the ground, I would suspect. I suggested that the plane that crashed somewhere in PA probably carried high explosives because its crash and attendant explosion caused a seismometer many miles away to register a significant reading of >2. Whereas the seismometer readings for the two earlier explosions in New York were relatively low and not as significant. Oh well, it may be the nature of the ground in New York state dissipated the energy of the crashes and/or explosions so much more effectively that nearby seismometers registered low and insignificant readings.
