The last few years have witnessed consistent growth in paleoseismic investigations and active fault research in India. An overview of relevant publications during 2016-2020 indicates that this field is now widely accepted as a tool to characterize the seismic hazard in the country. Such studies initiated in the country in early nineties have gained momentum and widened its scope into a variety of tectonic and morphological settings.While earthquake frequency and fault activations are major objectives of such studies, the Indian researchers are now equally interested in constraining the fault geometry and the nature of near-surface crustal deformation, thereby contributing to earthquake hazard evaluations. This has been driven by an ever-increasing interaction between experts from associated fields like geomorphology, neotectonics, seismology, geodesy, modeling etc. Future challenges would include integrating the paleoseismological observations with the relevant geophysical inputs to develop physical models of the earthquake cycles, ultimately leading to an inventory of the active faults. Although there are gaps and disagreements on how things operated at different spatial and temporal scales, there have been broad agreements in general. The future should focus on evolving new strategies and methodologies to integrate different datasets in a coherent manner to yield practically relevant results and models that can explain data from various spatial and temporal scales. © 2020 Indian National Science Academy.
