After half a year spent in Megolo di Mezzo, the drilling activities at the DT-1A borehole are now completed. The hole has reached a final depth of 909.5 metres, fully cored! A little closing ceremony took place at the end of April (see photo), before borehole logging activites on site, and final core description and sampling party in the core repository (in preparation). A big THANK YOU to everyone who has contributed the successful operations!

L’équipe de la RTS s’est rendu sur le site de forage scientifique DIVE début janvier pour amener des nouvelles du projet aux auditeurs/auditrices. Vous pouvez écouter le reportage paru dans l’émission CQFD du 23 janvier ICI.
Cependant, le forage a atteint 475 m de profondeur, et continue d’amener des carottes intéressantes.
We are proud to announce the opening of a participative gravity-modelling challenge on new (never used) data, in an effort to constrain the shape of the Balmuccia peridotite body while avoiding biases as much as possible. The full dataset and the detailed description are now available here, a summary can be found here, and the data are shown in the map below.
The second project DIVE borehole, located in Megolo, is now at 315.3 m depth below surface, and prepared for a pause over the year end break. One of the last cores was a beautifully recovered 3-m-long piece of metagabbro, standing with two “columnar” (~stalwart) members of the project on the photo below. Other photos and daily news can be followed here; on-site activities are planned to resume in January 2024.
“In August 2023, a series of earthquakes unprecedented in the Great Hungarian Plain began near the town of Szarvas. Several newspaper articles have made certain or almost certain claims about the events. However, understanding such a swarm of earthquakes requires much more data, geophysical modelling, and considerable research time. For this reason, and on the basis of what we know today, the probability of the earthquakes around Szarvas being related to human activity cannot be established with certainty.”
This is the English abstract of a study which appeared in Hungarian in the journal Magyar Tudomány (=Hungarian Science), available here.
The deformation of the Himalayan orogen is rather well known on geological timescale (millions of years) and modern, instrumentally observed timescales (decades). But how does it behave at intermediate timescales? Constraints to give an answer to this question are now available, and are presented and discussed in our new paper in Geology.
A book trilogy has been published this Summer as a result of a broad collaborative effort by geoscience experts working on the Himalayan mountain belt. The series has been edited by iSTE and co-published by Wiley, under the editorial work of Rodolphe Cattin and Jean-Luc Epard. Over a total of about 900 pages, the readers can read about:
In our reviewed opinion paper published in the Diamond Open Access journal Seismica, we underscore Nepal’s high earthquake vulnerability and outline an all-encompassing education policy tailored to its needs, crucial for raising awareness across society. See a tweet, a short video, and the Nepali abstract just below.
