Northern Pakistan has many hot springs, but the lack of direct measurements leaves the temperatures deep beneath these mountains poorly constrained. Using computer models, we show that heat from naturally radioactive rocks and the upward movement of hot crust can produce unusually high underground temperatures, especially beneath steep valleys. Our results identify deep valleys in the Nanga Parbat and Karakoram regions as promising areas for future geothermal exploration.

Deep geological repositories are considered one of the safest solutions for the long-term disposal of nuclear waste. This paper presents an overview of an experiment conducted at the BedrettoLab, Switzerland, where a new 100 m long tunnel was excavated in granite at a depth of 1300 m to investigate excavation-induced rock damage and its time-dependent evolution.

We developed faster methods for simulating Earth's interior dynamics. Standard iterative algorithms struggle to solve these equations efficiently. We introduced two improvements. First, we reformulated how calculation errors are measured. Second, we added a mass conservation correction. The first reduces the number of expensive solves, and the second improves accuracy over long simulations. We tested the method on several benchmarks, and both improvements come at little extra cost.

The shape of the water filled cavity hidden beneath ice shelves is extremely important, but hard to measure. Gravity data collected from aircraft can be used to predict the shape. However, in the Dotson Crosson ice shelves in West Antarctica, new direct observations from autonomous platforms sent beneath the ice, and seismic observations from the ice surface showed gravity models were systematically too shallow. We explain why and provide a solution applicable her and in other ice shelves.

This study examines shear wave splitting of core-refracted seismic phases from earthquakes to determine seismic anisotropy in unexplored areas of Central India. Understanding seismic anisotropy is essential for gaining insights into past geodynamic processes and current tectonic activities in the area. Our findings show that mantle deformation is influenced by both present plate motion and prior orogenic events, such as subduction, collision, and mantle plume activity within the study region.
