Så här skriver signaturen, Elfenlied, på Metabunk.orgs forum:Dvs, den upplevda frånvaron av seismiska signaler från explosioner är långt ifrån några bevis för att sådana inte förekom. I synnerhet om det är mindre kunniga som mäter samt analyserar samma mätvärden. Eller om man redan från GO är implicerade i ett inside job.
”Using seismographs for liability purposes doesn't make them [Protec] seismologists.
The USGS report on the Kingdome demolition in 2000 writes:At least three parallel sets of coherent P-wave arrivals are observed. These arrivals are preceded by less prominent arrivals that may represent the signals produced by the demolition charges themselves.They used 228 seismographs, 5 different types, most of them buried underground, placed in a hexadiagonal grid covering Seattle and centered around the Kingdome, not for some liability purposes or measuring earthquakes, they were placed there for one reason: to record the seismic signature of the demolition. But when they publish the preliminary report two years later, these professional seismologists are not prepared to say anything more definite than "may represent".
And there is a big difference between blowing up concrete and cutting through steel: With concrete the charge is placed inside, most of the energy is transferred to the structure. With cutting charges a metal liner is pushed together into a thin layer of liquid metal that moves at speeds in excess of 10 km/s, cutting through the steel; little energy is transferred to the rest of the structure, it's like the tablecloth trick: if you pull fast enough inertia will keep the plates and glasses in place.
We've seen other amateur interpretations of seismic recordings of 9/11, all of them bullshit. Leave seismology to the professionals.”

Simply put, there are countless causes of sharp, loud noises that have no relation to explosives.Två lögner här:
The only scientifically legitimate way to ascertain if explosives were used is to crossreference the fundamental characteristics of an explosive detonation with independent ground vibration data recorded near Ground Zero on 9/11.
1. Det är knappast den enda vetenskapligt legitima metoden. Att testa rasrester för spår av explosiver och incendiaries är däremot en väl beprövad vetenskapligt legitim metod, som dessutom rekommenderas i NFPA’s riktlinjer för åtgärder vid ”high-damage events”, som ju händelserna i WTC, 9/11, med råge uppfyller kriterierna för att vara.
2. Det är inte ens någon metod som kan sägas vara vetenskapligt legitim. Se nedan.

Ett mycket stort antal nedgrävda seismografer placerades hexadiagonalt med King dome i centrum, specifikt för att registrera varje nyans av den stundande kontrollerade demoleringen, ”to record the seismic signature of the demolition.”
The only scientifically legitimate way to ascertain if explosives were used is to crossreference the fundamental characteristics of an explosive detonation with independent ground vibration data recorded near Ground Zero on 9/11.... är av skälen angivna ovan inte bara grovt vilseledande, det är en ren lögn.
Furthermore, for a shaped charge with an explosive weight equivalent to or higher than 9 lb (detonated in a single delay), the noise level at a distance of 1/2 mile would have been on the order of 130 dB to 140 dB, roughly equivalent to that of a thunderclap directly overhead or an adjacent jet engine. The sound blast in an urban setting would have propagated by being channeled down streets with minimum attenuation. The hard building exteriors would have acted as nearly perfect reflectors, with little to no absorption. The sound would have been attenuated behind buildings, but it would also generate multiple echoes. This could have extended the time period over which the sound could possibly have had an additive effect if multiple in-phase reflections met.
People on the street would have heard 9 lb of RDX go off a mile away in air (and even further away if the wind were blowing in their direction). There were no witness reports of such a loud noise, nor was such a noise heard on audio tracks of video tapes that recorded the WTC 7 collapse.
For example, it is unknown how thermite’s destructive process could have been applied and initiated simultaneously on so many beams – in several buildings – undetected and/or under such extreme conditions. It is also unusual that no demolition personnel at any level noticed telltale signs of thermite’s degenerative “fingerprint” on any beams during the eight months of debris removal.– Science fiction.
..
In an effort to further research this assertion, we spoke directly with equipment operators and site foremen who personally extracted beams and debris from Ground Zero (several of whom have requested anonymity to prevent harassment). These men worked for independent companies in separate quadrants of the site, and many were chosen due to their extensive experience with debris removal following explosive demolition events. To a man, they do not recall encountering molten structural steel beams, nor do they recall seeing any evidence of pre-cutting or explosive severance of beams at any point during debris removal activities.
Several demolition teams had reached Ground Zero by 3:00pm 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 hearing or seeing nothing to indicate an explosive detonation precipitating the collapse.Brent Blanchard
