In this week’s blog, Shreeja Das,  a Post Doctoral researcher at the Sami Shamoon College of Engineering, Ashdod, Israel working with Dr. Vladimir Frid, discusses her research involving the use of FEMR waves and its use as a tool in predicting impending geohazards , some of her results obtained using said technique to study transform fault activity along the Dead Sea Transform fault.

Every now and then, the surface of our planet shakes violently during earthquakes like the recent magnitudes 7.8 and 7.5 Kahramanmaraş Earthquake Sequence in Türkiye. These vibrations are recorded by instruments called seismometers and are then processed and analyzed by seismologists to study the earthquake processes themselves as well as other deep Earth structures. Interestingly, seismometers al ...[Read More]

Into the anisotropic Earth

While we have sent several rovers to Mars, drilling down even just to the mantle of our own planet is a challenge that we are yet to overcome. How is it then that we know all these things about our planet’s interior? It turns out, we do not need to be inside the Earth to know what is happening there. Observations from geophysics and geochemistry can inform us about the processes and the properties ...[Read More]
