SUMMARY

Geologists are advancing their ability to visualize subducted slabs, significantly enhancing the understanding of Earth's history over the past 250 million years. The 2012 Fall Meeting of the American Geophysical Union (AGU) showcased seismic tomography as a pivotal tool in this research, demonstrating substantial improvements since the late 1990s. The ability to process seismic "noise" has refined the techniques used in seismic tomography, making it an invaluable resource for geologists. Key posters from the AGU meetings illustrate these advancements and can be accessed for further insights.

PREREQUISITES
  • Understanding of seismic tomography techniques
  • Familiarity with geophysical data processing
  • Knowledge of geological time scales
  • Basic concepts of plate tectonics
NEXT STEPS
  • Research advancements in seismic tomography since 2012
  • Explore the impact of seismic noise processing on geophysical studies
  • Study geological history through subducted slab analysis
  • Review AGU conference materials for recent findings in geoscience
USEFUL FOR

Geologists, geophysicists, and researchers interested in plate tectonics and the historical analysis of Earth's geological processes will benefit from this discussion.

The 2012 Fall Meeting of the AGU had a special session on seismic tomography. At that point it had come a long way from the stuff I was looking at in the late 1990's. Since 2012, with the ability to process and utilize "noise" and other refinements, seismic tomography has become an awesome tool. Here are a couple posters from the 2012 meeting:

I can't take credit for it, stole it from the article.
