One of the seismologists, Won-Young Kim, told AFP that the Palisades seismographs register daily underground explosions from a quarry 20 miles away.
These blasts are caused by 80,000 pounds of ammonium nitrate and cause local earthquakes between Magnitude 1 and 2.
Rules governing the maximum size and weight of vehicles differ among the States in the US. However, since the majority of hauling is done on the interstate system, the vast majority of trucks and trailer made in the US are built to the specifications of the Department of Transportation which governs the use of the interstate system. The D.O.T. has established vehicle limits of: 102 inches wide, 13.5 feet in height, and 80,000 lbs gross weight.
so, i guess what my point is is this: did anyone see 12.5 tons of explosives going off in the instant the towers started to collapse?

Damocles, no need for apologies in advance.
Most people interested in 911 make the same error, they look at the main seismic spikes from LDEO, and then conclude that those depict explosives.
They can not be further from the truth.
The signs of explosives lay much earlier in the graphs of the 3 collapses.
But are camouflaged/minimized by changing the sensitivity of these collapse graphs to a ten times less sensitivity, compared to the plane crashes.
From 10 nm/sec to 100 nanometer/second.
Thus the graphs look the same at first sight, but they are not.
All three collapse graphs are depicted in 100 nm/sec, while both two plane crashes are depicted in 10 nm/sec, which is ten times more sensitive.
If you change the collapse graphs to the same 10 nm/sec sensitivity, you will suddenly see in all three graphs, that the main spikes (now immense on the graphs) are precluded in ALL three graphs by identical big SEISMIC spikes, which have a magnitude nearly exactly the same height, thus magnitude, as the main spikes in the plane crashes graphs.
In short :
The three COLLAPSES begin ALL three with an IDENTICAL event, comparable to the head-on IMPACT of a nearly fully jet-fuel loaded commercial airliner.

my bad, a typo/mistake of mine in my post here, but if you look at my link, and scroll to post #4 from bsbray there, you see the 2 collapses of WTC 1 and 2 at the same sensitivity of 10 nm/sec depicted as the collapse of WTC 7, which was already noted by LDEO at the 10 nm/sec scale.
Edit : thus no need at all to revisit my own links to LDEO. EndEdit.
It is in fact that event at WTC 7 which is clearly the BIGGEST magnitude event in that graph, but taking place before the global collapse of WTC 7, which alerted me to dig deeper in the whole seismic events subject.

(Excerpts) "Several demolition teams had reached Ground Zero by 3:00 pm on 9/11, and these individuals witnessed the collapse of WTC 7 from within a few hundred feet of the event.
We have spoken with several who possess extensive experience in explosive demolition, and all reported seeing or hearing nothing to indicate an explosive detonation precipitating the collapse.
As one eyewitness told us, "We were all standing around helpless...we knew full well it was going to collapse. Everyone there knew. You gotta remember there was a lot of confusion and we didn't know if another plane was coming...but I never heard explosions like demo charges. We knew with the damage to the building and how hot the fire was, that building was gonna go, so we just waited, and a little later it went."
"Any detonation of explosives within WTC 7 would have been detected by multiple seismographs monitoring ground vibration in the general area. No such telltale 'spike' or vibratory anomaly was recorded by any monitoring instrument."
