The whole group is contributing to the 16th Swiss Geoscience Meeting in Bern, with one poster per person, in sessions 1, 7 an 16. Check the meeting program here.
The first paper on crustal structure in western Nepal, a study from our group, is recently accepted for publication in Geophysical Research Letters (GRL). The Moho and the Main Himalayan Thrust (MHT) is investigated using the receiver function technique. It should be an important finding as the Moho and the MHT is poorly known in the area. Now, it has a DOI and can be officially cited.

Magnitudes of differential stress in the lithosphere, especially in the crust, are still disputed. Our recent work addressing this topic with numerical modelling and geophysical data from the field has just been accepted at Geophysical Journal International:

The 33rd HKT conference is over and we keep a great memory of this event! A final, post-conference message is yet to come, with the group photo, the keynote speech’s video, etc.
Following the advice of one of the participants and a good colleague, I here share the PDF version of a 7-year old article that is not so visible, showing that seismic low-velocity zones in South Tibet are present in spots, and do not form a continuous layer.
After more than a year preparation, the 33rd Himalaya-Karakorum-Tibet workshop is at the doorstep. From Monday to Wednesday next week (Sept. 10-12) more than 130 researchers will present ca. 45 talks and ca. 85 posters on the structure, dynamics and natural hazards of the HKT region. The invited keynote speaker is Peter Molnar (U. Colorado), who will talk about the Growth of the Tibetan Plateau. About 35 people will also go on a 3-day field excursion in the Western Swiss Alps before the workshop. Full information can be found at the HKT2018 website. We look forward to host the event and the participants.
General knowledge of geoscientists holds that earthquakes occur on faults, and faults are created by brittle failure. But how good is the spatial correlation between the two datasets? This is the question we have analyzed from various sides in our freshly published paper.
Our work on the seismotectonic interaction between the Bhutan Himalaya and the Shillong Plateau has just been published in Tectonophysics. The results point to a weaker interaction between thrust faults in the two regions than previously suggested. Earthquakes on these thrusts mostly affect strike-slip faults connecting the two regions, so there is no “stress shadow” effect from the 1897 earthquake on the Bhutan Himalaya.
