Geophysical studies to decipher the subsurface features in Joshimath, Uttarakhand, India
Description: P 519-527Subject(s): In: Current ScienceSummary: Joshimath, a geologically fragile region in the Garhwal Himalayas, is experiencing land subsidence due to natural and anthropogenic factors. A multi-instrumental geophysical survey, including Electrical Resistivity Tomography (ERT), magnetic susceptibility analysis, and ground magnetic surveys, was conducted to assess subsurface conditions. ERT results reveal weak zones with water saturation and resistivity variations linked to fractured and compact gneissic formations. Magnetic susceptibility analysis highlights variations in mineral concentration, while ground magnetic surveys identify subsurface structures and lineaments associated with instability. These findings provide critical insights for hazard assessment and sustainable development in Joshimath and other vulnerable Himalayan regions.| Item type | Current library | Call number | Vol info | Status | Barcode | |

Joshimath, a geologically fragile region in the Garhwal
Himalayas, is experiencing land subsidence due to natural and anthropogenic factors. A multi-instrumental
geophysical survey, including Electrical Resistivity
Tomography (ERT), magnetic susceptibility analysis,
and ground magnetic surveys, was conducted to assess
subsurface conditions. ERT results reveal weak zones
with water saturation and resistivity variations linked
to fractured and compact gneissic formations. Magnetic
susceptibility analysis highlights variations in mineral
concentration, while ground magnetic surveys identify
subsurface structures and lineaments associated with
instability. These findings provide critical insights for
hazard assessment and sustainable development in
Joshimath and other vulnerable Himalayan regions.
