Onset of WTC1 Movement and Sauret Shake

Analysis, observations and theory related to initiation.

Onset of WTC1 Movement and Sauret Shake

Postby femr2 » Fri Jul 02, 2010 1:13 pm

Recent tracing appears to show that movement of WTC 1 features, such as the NW corner, Washer and antenna begins during/immediately after the Sauret footage camera shake.

Initial movement is horizontal, rather than vertical.

There is, of course, also the piece of debris ejected from the NW corner of WTC 1 at the onset of the camera shake, which I'm sure has been the subject of discussion in the past, but correlation to the latest trace data raises (or re-raises) an important question.

I shall of course post the trace data and graphs here soon, but am starting the thread now to try and ensure that we're looking at multiple data-sets. (OWE & Achimspok :) )

Diving right in and asking questions...

If we agree that building deformation begins at the same time as the camera shake, and at the same time as visible ejecta from the NW corner (fl 104/5)...is it reasonable to conclude the events are linked ?

If so, then what events could result in the camera shake ?

Seismic activity ? If so, it would not be localised, so should appear on seismic records, yes ?

Basement disturbance ? What scale of *explosion* would result in camera shake at the camera location, but not on seismic records ?

And of course...IF the shake is the end result of a *boom* in the basement, then how would destabilising the core at that location be expected to present itself in upper levels ?

(I have thoughts on answers to these questions, but looking for things I might not have thought of before making any serious *claims*...maybe just an unfortunate mini-earthquake ? ;) )

Also, and it's admittedly a bit of a stretch, but will be borne out by some data...

It also appears that features on the West side move Eastwards, whilst features on the East side move Westwards.

This would suggest, to me at least, that a form of *pull in* is occuring.

I'd imagine that if the core (or a section of it) began to *sag* or move downwards, then it would *pull in* the floors and perimeter.

Would that also be a mechanism to perhaps explain the perimeter *kick-out* behaviour at initiation ?

A spoiler...

Image

You should be able to tell where the camera shake is (between frames 1150-1250).

Black thick line is horizontal movement of the NW corner.

Grey is raw NW corner.

Blue is static point.

(Remember there would be a time delay between event and camera if indeed it originated from the WTC ;) )

Static points...

Two static points are used, one in the foreground (on the building on the left of frame), and one low on the East side of the building.

The following graph compares and shows the difference between both static points...

Image

Blue is FG static point.
Grey is Building static point.

Black is the difference.

Note...

1) There is good correlation between both until near the very end of the trace, indicating that parralax effects are minimal between near and far field objects.

2) There is Westward movement of the static point on the building at the end of the trace.

3) Camera shake period should be obvious.

Static Feature Comparison (Vertical)

Image

Notes...

1) Slight gradual vertical drop of building static feature following camera shake.

I'm aware of stating movement of static features here, but I was expecting the traced point on the building to *stay* static. The actual location is here...

The foreground static feature...

Washer Horizontal Movement (Normalised to FG static point)...

Image

Notes...

1) Remember camera shake is between 1150 and 1250.

2) Eastward movement follows shake.

Base video...

http://xenomorph.s3.amazonaws.com/Etienne-Sauret-WTC1-DVD.mpg

My Frame 1 = Frame 370 in the deinterlaced mpg.

Processing...

1) Deinterlace - unfold.
2) VideoEnhancer Resolution Upscale (*2x, *4y)
3) Deinterlace - fold.
4) Bob Doubler (Alternate Fields, No resize)

Only looking at the first 1300 (interlaced), 2600 (deinterlaced) frames.

Written out as .bmp you should end up with 2600 files, totalling 10,782,860,400 bytes (10 Gb)

Examining... but time is limited.

I don't wish to jump to conclusions, either way.

Edit: I had a big post with all the usual and expected seismic/acoustic rahrah, then I noticed something in your plots, and I decided against it for the time being.

No worries.

I have the video data to hand, so if there are other traces or whatever you'd like to see, no probs...


Am certainly intending on replicating all details with alternate tracing locations.

What did you notice ? :)

It's the shape of the time-averaged traces. Both the nature of the shape, and the difference in shape between the two measured points. Wasn't what I expected.

The two static point traces ?
