Seismic refraction analysis of landslides

• Presented by Hasan Ramadhan-PowerPoint Slides

Since I'm so interested in this topic, could you mention to me its author name?
Charles F. Narwold and William P. Owen
Could you mention to me the two assumptions for applying the GRM?
ü- A layered model.
ü- Continuity of refractor surfaces across a profile.
What types of the GRM analysis can be used?
The approximate velocity (AP) and the average velocity (AV) methods.
What was the final result fr the N1 profile?
The velocity distribution of a landslide along the Navarro River can be explained by a rotational slide superimposed on a larger landslide with fracturing and displacement extending into bedrock.

• Refraction Microtremor (ReMi) Method

  • Presented by Ahmed Al Zawwad-PowerPoint Slides

• 1)

 What is the meaning of physical restriction? : It refers to restriction causedby the volume of the body. 

What does SCPT do for   SeisOpt® ReMi™? : It is an other method and it does not effect the SeisOpt® ReMi™.

What is the microtremor?: Standard refraction equipment deployed similar to a shallow P-wave refraction survey to record ambient noise

• Velocity Models for the Highly Extended Crust

Use of Advanced Data Processing Techniques in the Imaging of the Coso Geothermal Field - Satish Pullammanappalil, Bill Honjas, Jeff Unruh, and Frank Monastero
During December of 1999, approximately 32 miles of seismic data were acquired within the Coso Geothermal Field, Inyo County, California, as part of a detailed seismic investigation undertaken by the US Navy Geothermal Program Office. Data acquisition was designed to make effective use of advaddnced data processing methods ...click here to download the pdf.
