edited by Giridas Maiti

Giridas Maiti is a postdoctoral researcher at the Karlsruhe Institute of Technology (KIT), Germany. He is currently investigating the geodynamic causes for slab breakoff and tearing processes in the Alps and their impacts on the tectonics of the North Alpine Foreland Basin (NAFB) using 3D numerical modeling. During his Ph.D., he worked on geodynamic modeling of the subduction-collision process in the spatiotemporal evolution of the Himalaya-Tibet mountain system. Giridas is part of the GD blog team as an editor. You can reach Giridas via email (giridas.maiti@kit.edu).

T for temperature in seismic [T]omography and more

Seismic tomography, a powerful geophysical technique, is like the Sherlock Holmes of the Earth’s interior. It helps us uncover crucial information about the lithosphere and mantle, including temperature and density distributions. Understanding these physical properties is vital for a wide range of geological applications, from identifying regions of strain localization to assessing geotherma ...[Read More]

How does slab tearing evolve?

Slab tearing refers to the gradual propagation of the break-off of a subducting plate. As observed in numerous modern and ancient convergent tectonic settings, the growth of the tear “window” in the downgoing plate has strongly influenced various geologic and geodynamic processes, such as depocenter migration of foreland basins, uplift rates in mountain ranges, earthquakes, volcanism, and flow pat ...[Read More]

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies
Locations of the Quaternary arc and intraplate volcanoes in Northeast Asia, depicted as black triangles, with major plate boundaries. Modified from Kim et al. (2015).

Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China have occurred abo ...[Read More]

Effects of decelerating India-Eurasia convergence on the crustal flow and topographic evolution of the Tibetan Plateau

Effects of decelerating India-Eurasia convergence on the crustal flow and topographic evolution of the Tibetan Plateau

The Tibetan Plateau is the most extensive elevated surface on the Earth, stretching ~1,000 km north to south and 3,200 km east to west, with a mean elevation of greater than 4.5 km and located north of the Indian subcontinent. The formation of this Plateau has profoundly influenced the variations and evolution of Asian climate, strengthening of the South-Asian Monsoon, development of the large Asi ...[Read More]
