I think the idea behind using HAARP for earthquakes is that you can use it to generate very low-frequency waves and get parts of the Earth's crust to resonate, eventually setting off an earthquake.
I wouldn't be at all surprised if somebody's got it working by now.
The fact that unpleasant people or obvious shills promote various 'theories' doesn't mean that the theories themselves are without merit.
I think Simon once made a comment about the perpetrators' use of easily-discredited rude and annoying provocateurs to 'inoculate people against the truth', and I think he's right. The fact that we have "Dr Judy Wood" supposedly promoting space weapons while the 911Blogger shills and Alex Jones fans ridicule her AND ridicule TV-Fakery doesn't tell us anything about space weapons. They've got a fairly elaborate song-and-dance routine with choreographed fights going on, with various shills promoting a mix of truth and fiction and arguing with each other.
Looking back at Judy Wood's work, it seems to me that a big part of the idea behind using her was to further cement the idea that the videos were 'real records of the events' and to chalk up a bunch of the
physical impossibilities shown in the video to
unknown advanced scientific weaponry rather than
crappy special effects.
Knowing what we know now, there's no reason to assume that the towers turned directly to dust, or that the 'spire' was any more real than any of the other fake images of the day. Once that bogus evidence is thrown out, there's less need to use exotic weapons to explain the destruction of the towers. I'm not sure how anybody can know exactly how high the rubble pile was, either, given the lockdown on photography right after the towers were demolished.
My gut feeling is still that they rigged the towers with conventional and unconventional explosives and probably field-tested various exotic weapons on the different WTC complex buildings. I would imagine that the temptation to use the latest toys to demolish some giant skyscrapers would have been difficult to resist.

Such weapons, whether or not they exist or are feasible, are a source of concern in official circles. For example US Secretary of Defense William S. Cohen, said on 28 April 1997 at the Conference on Terrorism, Weapons of Mass Destruction, and U.S. Strategy, University of Georgia "Others are engaging even in an eco-type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves."[3]
[edit] International treaties
The 1978 Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques is an international treaty ratified by 75 states, and signed by a further 17, that prohibits use of environmental modification techniques to cause earthquakes and tsunamis, amongst other phenomena[4].
