Seismic Scattering: Topography, Faulting, Fluid/Melt

Click For Summary
SUMMARY

This discussion focuses on the effects of topography, faulting, and fluid/melt on seismic scattering. It establishes that seismic scattering occurs due to wavefield interactions with heterogeneities comparable to the incident wavelength. Topography is identified as a geometric factor influencing scattering, while faulting and the presence of fluids or molten rock alter seismic wave propagation due to differences in elastic properties and sound speed. The conversation encourages further exploration of these topics through scientific literature.

PREREQUISITES
  • Understanding of seismic wave propagation
  • Familiarity with geological structures such as faults
  • Knowledge of fluid dynamics in geophysical contexts
  • Basic principles of elasticity and sound speed in different media
NEXT STEPS
  • Research the impact of topography on seismic scattering using resources like the Lunar and Planetary Institute's publications
  • Investigate the role of faulting in seismic wave behavior and scattering
  • Examine the effects of fluid and melt on seismic wave propagation and their elastic properties
  • Study the mathematical modeling of seismic scattering in heterogeneous media
USEFUL FOR

Geophysicists, seismologists, and researchers in earth sciences seeking to understand the complexities of seismic scattering and its influencing factors.

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?
