Earthquake Source: Mechanics, Seismology and Geology

Scientific Themes

Strain, Seismicity and Hazards in the Himalaya

SSH

We invite abstracts on observational, laboratory, numerical and theoretical studies addressing interseismic strain accumulation and seismicity throughout the Himalaya, emphasizing the intricate links among tectonic deformation, crustal dynamics, and structural variability. Contributions examining spatial or temporal strain patterns, fault behavior, and their connection to both large and small earthquakes are encouraged. Geodynamic studies investigating mantle-scale processes that influence upper-crustal strain buildup are also welcome. Research integrating geodetic, geological, and seismological observations to reveal how Himalayan architecture governs stress transfer and earthquake occurrence is also of particular interest. Finally, we welcome studies that integrate all of the processes above to forecast earthquake hazards in the Himalayas.

Intraplate Earthquakes — Occurrence, Processes and Geology

IE

We invite abstracts on observational, laboratory, numerical, and theoretical studies exploring intraplate earthquakes, focusing on their occurrence within the Indian subcontinent and beyond, the underlying processes, and geological context. Contributions examining structural, rheological, and compositional controls on fault reactivation, stress accumulation, and seismicity within stable continental interiors are encouraged. Studies integrating geological mapping and geophysical data to investigate the timing, recurrence, and mechanics of intraplate earthquakes are also welcome. We especially encourage research utilizing borehole data to examine subsurface petrological, rheological, frictional, and mechanical factors controlling the occurrence of intraplate seismicity.

Physics of Earthquakes: Theory and Experiments

PE

We invite abstracts on observational, laboratory, numerical, and theoretical studies exploring the physics of earthquakes, focusing on fault slip, rupture propagation, and energy release. Contributions linking models or experiments to real-world earthquake observations are encouraged, including the roles of friction, fluids, lithology, fault-zone geometry, and tectonic or non-tectonic stress perturbations. We also welcome studies connecting theoretical frameworks with experimental and field-scale data to advance understanding of earthquake mechanics, scaling laws, and the physical controls on initiation, rupture, and magnitude.
