Seismic Scattering: Topography, Faulting, Fluid/Melt

AI Thread Summary
Seismic scattering is influenced by several factors, including topography, faulting, and the presence of fluids or melt. Topography affects seismic waves through geometric variations and differences in material interfaces, leading to scattering as waves interact with these features. Faulting introduces discontinuities in the Earth's crust, which can cause reflections and refractions of seismic waves, altering their paths and intensifying scattering effects. The presence of fluids or molten rock significantly impacts seismic behavior due to differences in elastic properties and sound speed compared to solid rock. These variations can enhance scattering, as the heterogeneous nature of these materials interacts with seismic waves at similar scales to the wavelengths involved. For further reading, scientific sources provide detailed insights into these phenomena and their implications for seismic studies.

How do the following affect seismic scattering ?

1) topography
2) faulting
3) fluid and melt

Any scientific sources are appreciated, thanks

What have you found in your reading so far?
 
I know that seismic scattering occurs as a result of the wavefield interaction with a heterogeneity that is of a similar scale length to the incident wavelength, but i do not know how each of these particular entities has an effect, if at all ?
 
OK I am not going to do them all for you, since I am sure you really do know how to use google

put your questions into google one at a time ... I did the first one for you

how does topography affect seismic scattering ?

and as an example, got ...

now have a play and see what else you can find :)

cheers

Topography would be a geometric effect, in addition to differences in interfaces between different media.

What is a fault?

What is the significance of fluid or molten rock - as compared to solid rock? Think about the speed of sound and elastic properties?

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'
(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
