Fault Geometry Control on Earthquake Segmentation and Locking Transition on Mid‐Crustal Ramp in Kumaun‐Garhwal, Central Himalaya: Implications for Regional Tectonics and Seismic Hazard Open
The Himalayan arc experiences numerous earthquakes that rupture its different segments at different times. Considerable attempts have been made to find discernible patterns and understand the underlying physics that can enable reliable for…

Present day mantle structure from global mantle convection models since the Cretaceous Open
SUMMARY Using forward mantle convection models starting at 140 Ma, and assimilating plate reconstructions as surface velocity boundary condition, we predict present-day mantle structure and compare them with tomography models, using geoid …

How the Indian Ocean Geoid Low Was Formed Open
The origin of the Earth's lowest geoid, the Indian Ocean geoid low (IOGL) has been controversial. The geoid predicted from present‐day tomography models has shown that mid to upper mantle hot anomalies are integral in generating the IOGL. …

Convective self-compression of cratons and the stabilization of old lithosphere Open
Despite being exposed to convective stresses for much of the Earth’s history, cratonic roots appear capable of resisting mantle shearing. This tectonic stability can be attributed to the neutral density and higher strength of cratons. Howe…

Convective self-compression of cratons and the 1 stabilization of old lithosphere Open
Key Points: 13 • Mantle flow leads to inwardly convergent tractions around the edges of cratons, 14 and compressive stresses within. 15 • Convergent tractions result from the downward diversion of mantle flow. 16 • This convective self-com…

Interaction of the Indian craton with the Reunion plume Open
<p>One of the fundamental characteristics of cratons is the presence of thick lithosphere of more than 200 km, whereas any standard non-cratonic lithosphere thickness is about 100 km thick. The thickness of Indian craton has remained…

Understanding deformation of cratons in presence of mid-lithospheric discontinuity Open
<p>The recent discovery of mid-lithospheric discontinuity (MLD) within most cratons has added a new dimension in the understanding of cratonic survival. The MLD shows up as a seismic discontinuity at ~80-160 km depth. However, there …

Traction and strain-rate at the base of the lithosphere: an insight into cratonic survival Open
SUMMARY Cratons are the oldest parts of the lithosphere, some of them surviving since Archean. Their long-term survival has sometimes been attributed to high viscosity and low density. In our study, we use a numerical model to examine how …

The Importance of Upper Mantle Heterogeneity in Generating the Indian Ocean Geoid Low Open
One of the most pronounced geoid lows on Earth lies in the Indian Ocean just south of the Indian peninsula. Several theories have been proposed to explain this geoid low, most of which invoke past subduction. Some recent studies have also …

Surface motions and intraplate continental deformation in Alaska driven by mantle flow Open
The degree to which the lithosphere and mantle are coupled and contribute to surface deformation beneath continental regions remains a fundamental question in the field of geodynamics. Here we use a new approach with a surface deformation …
