Talk:Seismic wave

message: Surface waves do NOT cause most damage in earthquakes.  High horizontal accelerations responsible for most damage are associated with shear waves (S-waves).  Some geologists think that, because the surface wave traces are largest on seismograms from distance earthquakes, that surface waves cause the damage.  Although the displacement of surface waves is usually higher than that of shear waves at teleseismic distances, horizontal accelerations are highest in the near field when the shear waves arrive, and these high horizontal accelerations do the damage.
This error has propagated through generations of physical geology textbooks.
Some seismologists are looking into a new kind of surface wave called a basin-generated wave, but strong motion seismograms usually reveal that the damaging motions are inconsistent with classical Love or Rayleigh waves, the surface waves well recorded hundred to thousands of kilometers from large earthquakes.
Shear wave amplification and resonance in the soft sediments of deep basins is a well know and understood phenomenon.

message: In general, I find this article too long and comprehensive, with few outside references.  Would it be good for a highschool project?  I have started to divide some of these things into 1-page focused articles.  These are then good for links in other articles.  It's a question as to the 'social purpose' of the wiki ???  --Zeizmic 16:44, 13 December 2005 (UTC)
replies: text: This is correct - commonly referred to as microseismicity. For example, every time a wave breaks on the shore, the impact sets up waves which you can see on seismograms. It is clearly visible in a comparison of seismic records from stations on islands, as compared to those in the middle of the continents. And don't get me started on stations near motorways... These seismic waves are not large, but they are detectable. J chaloner 22:47, 14 February 2007 (UTC)
thread_title: Length of Article

message: "In any case, waves of the reported amplitude, wavelength, and velocity of the "visible waves" have never been recorded instrumentally."  What about the Goodyear blimp during the '89 World Series earthquake in Loma Prieta, near San Francisco?  It demonstrated, for the first time, that the air column moved with the ground.  Well, based on how the air moved (proved by cameras and the blimps instruments), I think it's safe to say that the ground moved in this fashion.  Should I change the article to reflect this or does someone else have more information on this? Banaticus (talk) 09:37, 4 August 2008 (UTC)
thread_title:  Rayleigh waves 

message: I noticed the section explaining love waves describes them as being both faster than Reyleigh waves, but slowest as well.  I for one don't know which statement is true.  I would like to see someone who does know the answer to edit the article, then delete this portion of the discussion.
