Should we still study LLSVPs?

Should we still study LLSVPs?

All blobs are equal, but some blobs are more interesting than other blobs. In this new Wit & Wisdom post, Jamie Ward, PhD student in seismology at the University of Leeds, United Kingdom, explores this age-old saying and discusses whether or not LLSVPs are the most important blobs in our lives. Also, there is a picture of a dog. It makes sense, I promise. Large Low Shear Velocity Provinces (LL ...[Read More]

Enigmas at depth

Enigmas at depth

The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community in an understandable manner. In this week’s Geodynamics 101 post, Marcel Thielmann, Senior Researcher at the University of Bayreuth, discusses the possible mechanisms behind the ductile deformation at great depths that causes deep earthquakes.  Earthquakes are one of the expre ...[Read More]

On the resolution of seismic tomography models and the connection to geodynamic modelling (Is blue/red the new cold/hot?) (How many pixels in an Earth??)

What do the blobs mean?

Seismologists work hard to provide the best snapshots of the Earth’s mantle. Yet tomographic models based on different approaches or using different data sets sometimes obtain quite different details. It is hard to know for a non specialist if small scale anomalies can be trusted and why. This week Maria Koroni and Daniel Bowden, both postdocs in the Seismology and Wave Physics group in ETH ...[Read More]

Tomography and plate tectonics

The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to Professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. For our first ‘Geodynami ...[Read More]
