The study described here is based on the measurements of soil gas radon–thoron concentrations performed at Dharamsala region of north-west (NW) Himalayas, India. The study area is tectonically and environmentally significant and shows the features of ductile shear zone due to the presence of distinct thrust planes. Solid state nuclear track detectors (LR-115 films) have been used for the soil gas radon–thoron monitoring. Twenty five radon–thoron discriminators with LR-115 films were installed in the borehole of about 50 cm in the study areas. The recorded radon concentration varies from 1593 to 13570 Bq/m3 with an average value of 5292 Bq/m3. The recorded thoron concentration varies from 223 to 2920 Bq/m3 with an average value of 901 Bq/m3. The anomalous value of radon–thoron has been observed near to the faults like main boundary thrust (MBT and MBT2) as well as neotectonic lineaments in the region.

Use of GRACE time-series data for estimating groundwater storage at small scale
CH SAMUREMBI CHANU HARIKA MUNAGAPATI VM TIWARI ARVIND KUMAR L ELANGO
This study integrates the time series of satellite data, i.e. (terrestrial water storage (TWS) extracted from Gravity Recovery and Climate Experiment (GRACE), soil moisture (SM) from Global Land Data Assimilation System (GLDAS), rainfall from Tropical Rainfall Measuring Mission (TRMM)) with
$\bf{Highlights}$
$\bullet$ Areal extent of the study area is less than the optimum suggested for GRACE related investigation. The amplitude of the GRACE signal is 300 km and it is recommended that the study area to be larger than that. Our study is perhaps the first such attempt where the study area is much less than recommended.
$\bullet$ We were able to get a good correlation between $\Delta$GWGRACE and $\Delta$GWINSITU despite the challenge of spatial resolution.
$\bullet$ A significant finding of the investigation is that distinction in estimates of groundwater changes between GRACE estimates and
$\bullet$ The impact of various precipitation mechanisms in the examination area was contemplated.
