The Dr. Greg Jenkings interview opened my eyes wide open, regarding Mrs Wood.
Well, we also have a PAIR of waves, even a triple pair...
The WTC 1,2 and 7 seismogram from the first week after 9/11.
Just overlap them two Twin tower seismic collapse graphs, and see what wisdom that cross correlation technique will bring you.

Just overlap them two Twin tower seismic collapse graphs, and see what wisdom that cross correlation technique will bring you.
Thus you can work back on your 9/11 seismogram now, with cross correlation, to the arrival times of any predicted P-wave, S-wave and the Lg-wave.
The seismographs also recorded the impacts of the airplanes, the first at 8:46 a.m. (WTC1,N) and the second at 9:03 a.m. (WTC2,S), Dr. Sykes said. The tower collapses, he added, came at 9:59 (WTC2,S)and 10:28 a.m. (WTC1,N)
In Chelsea Park, near an expanse of green artificial turf, the researchers had set up four sensors — called broadband seismometers — topped with what looked like white mushroom caps. They were actually global positioning system antennas picking up shock waves as they migrated across the sensors, timing them in synchrony to 0.001 seconds.
(LT : This 0.001 secs timing specification was in 2001 about 0.01 seconds at LDEO and in their 9/11 WTC-seismograms !!! )
Placed in equilateral triangles — with one unit at the center — they recorded 30 minutes of measurements at different distances.
The testing employed an efficient, cost-effective new method that has replaced older seismic mapping techniques that used sledge hammers, movable weights and even explosive charges to generate shock waves.
The speed of the waves in the ground — determined by the thickness and composition of the soil, which measured from 30 to 100 feet of subsoil in each testing location — “determines how strong the shaking will be,” Dr. Frankel said.
The potentially deadly swaying force in earthquakes is produced primarily by low-frequency shear waves — called s-waves, he said. They pulse horizontally and vertically and shake soil — along with whatever structures are built there — like a bowl of Jell-O.
Instead of registering vibrations on vintage seismic drums with their jiggling pens, the data was forwarded to digital recorders and stored on magnetic cards.
After the data is mathematically analyzed, the scientists can calculate how much the earthquake waves would be amplified if there were a seismic event.
Ultimately, the readings will be used to compile a hazard assessment, which in turn will advise not only emergency-preparedness planners but also engineers and architects.
“If you know where the bad places are,” Dr. Frankel said, ”you can build buildings differently there.”

Felix Waldhauser, David Schaff, and colleagues present research aimed at increasing understanding of seismicity and fault structures throughout Northern California. The research team used the previously known techniques of waveform cross correlation to improve seismic arrival time measurements, and multiple event location techniques to reduce model errors. They applied these techniques on a massive scale to all 250,000 events recorded in the NCSN catalog of Northern California. The authors comment on and present results from ongoing efforts, based on these newly adjusted data, to produce more accurate and detailed images of fault structures in Northern California and their correlation with the local geology. Felix Waldhauser, Doherty Associate Research Scientist, LDEO ([email protected], 845-365-8538). Dr. Waldhauser with colleagues Bill Ellsworth and David Oppenheimer of the US Geological Survey, will also be discussing research on the recent Parkfield M6 earthquake in Central California that occurred on September 28, 2004.
Physics With a Twist
--snip--
Basic physics tells us that objects spinning at a very high rate tend to maintain their relative position in space, so an IMU incorporates several spinning gyroscopes. By measuring the angle of tilt as each spins a spherical mass within a gimbal (or cage), and coupling that with an accelerometer to keep track of shifts in velocity, the system can tell us how far, how fast and in what direction a target is moving relative to a given starting point. Usually, all the data collected from the various instruments, when combined, can give an elevation that is accurate to within 6 inches.

But because the wavelengths used are much shorter than radio waves, LIDAR systems are much better at detecting very small objects, like particles in the atmosphere. In fact, they are already used to study atmospheric conditions, notably the densities of various particles, not to mention all kinds of emerging applications in geology, seismology, and even archeology. Also, lasers use a very narrow beam, so LIDAR allows for mapping of physical features with much higher resolution than conventional radar. It can have a “footprint” of less than 1 meter, making it possible to map the floor underneath a forest canopy, or the urban canyons between tall buildings.

LaBTop, I want you to contemplate this:
Leo, I think you have a lot to contemplate about.
Page 38 of 63 : The Mueser Rutledge Consulting Engineers damage assessment schematics show that all 6 sub-levels (7 stories) across the entire footprint of the towers likely collapsed.
I will show in the remainder of this section that the photographic record of GZ debris removal from September 2001 through May 2002 clearly depicts all sub-levels directly beneath both towers collapsed and filled with debris. The amount of debris which compacted into the sub-levels across the footprints of the towers will be shown to be the majority of the material associated with the towers.
A summary of the current arguments compiled from the author’s current and previous reports (35) which have not been addressed by DEW-proponents are as follows:
I have been waiting years for the Truth movement to put together all their truther facts and tell us what happened on 9/11 in a way that doesn't make me giggle.
When you put all the truther facts together you get something like this:
Everyone will eventually know that al-Qaeda never existed, acted under the control of the US Government and acted on its own initiative but with the passive complicity of the US Government to hijack planes, not hijack planes and try but fail to hijack planes, that the US Government, a small rogue element within the US Government, and Mossad operating without the knowledge of the US Government crashed the planes into the towers under remote control, crashed different planes into the towers under remote control, didn't crash any planes into the towers but projected holograms of the planes crashing into the towers, and didn't crash or project anything but convinced everyone that planes hit the towers by showing it to them on TV, after which the towers were blown up by explosives that made lots of explosions that everybody heard, weakened by thermite silently which explains why nobody heard any explosions, blown up by nuclear weapons in the cellar which started collapses from the top, and turned entirely to dust by energy beams from space which is why there was no debris, and that the debris pile was then kept hot for months by thermite that hadn't reacted when it all reacted to bring the towers down, and all the steel that wasn't there was immediately taken to China which is why the steel recovered shows signs of explosives, melting and dustification, and a plane, a missile, a different plane and a hologram all crashed into the Pentagon except that it was only one of them, or pulled up at the last second and flew over the Pentagon, leaving a neat 12 foot hole that caused 90 feet of the bit of the wall that had recently been reinforced to collapse, and another plane was shot down at Shanksville then landed in Cleveland leaving no wreckage at Shanksville that was spread out over too large an area to be from a crash even though it didn't exist. That's what really happened, and some day everyone will figure out how obvious it all is.

It's been a couple of years since I asked you to put the facts together, are you able to do it now?
