In summary, geologists have made significant advancements in visualizing subducted slabs and hope to continue to improve their understanding of Earth's history through techniques like seismic tomography. The AGU Fall Meeting in 2012 and 2013 featured special sessions on this topic, showcasing the progress made in processing and utilizing seismic data. Several posters were presented, demonstrating the effectiveness of this tool.

All I can say is: man, that is one catchy thread title. :smile:

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.

nice posters, thanks
 

Related to Geologists Uncovering the Earth's History with Subducted Slabs

What is the process of subduction?

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle as the two plates converge.

What role do subducted slabs play in Earth's history?

Subducted slabs play a crucial role in plate tectonics and the formation of mountains, volcanoes, and ocean basins. They also affect the Earth's climate and the distribution of minerals and resources.

How do geologists uncover the Earth's history with subducted slabs?

Geologists study subducted slabs by analyzing rocks, minerals, and fossils found in the subduction zone. They also use techniques such as seismic imaging and deep drilling to understand the subducting plates and their impact on the Earth's surface.

What can the study of subducted slabs tell us about the past?

The study of subducted slabs can tell us about the past movements of tectonic plates, the evolution of Earth's surface, and the history of mountain building and volcanic activity. It can also provide insights into past climate and the distribution of ancient landmasses.

What are the potential hazards associated with subducted slabs?

Subducted slabs can cause earthquakes, tsunamis, and volcanic eruptions. They can also trigger landslides and affect the stability of coastlines. Additionally, the melting of subducted slabs can release fluids and gases that contribute to the Earth's atmosphere and climate.
