CoRSEER: the calculator of rock surface exposure age and erosion rates for luminescence rock surface exposure dating

Luminescence rock surface exposure dating (LRSED) estimates the duration of rock surface exposure and the rate of erosion by analysing changes in luminescence with depth below the surface. The wider use of this method has been slowed by limitations in mathematical analysis, such...

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Abstract The M w 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture rad...

An Update on the Geochemical Composition of Peninsular India Rivers Average Clay (PIRAC): A Regional Reference for River Sediments of Peninsular India

The rivers draining Peninsular India are rain-fed and their sediments are formed from weathering and erosion of continental rocks in the drainage basins. Peninsular India comprises dominantly the Archean–Proterozoic Terrain (APT) in the south, Deccan Trap Volcanic Terrain (DVT) i...

Assessment of groundwater quality for drinking and irrigation purposes using water quality index and statistical analysis in Nalanda district, South Bihar, India

This study evaluates the hydrochemical characteristics and overall suitability of groundwater in Nalanda district, Southern Bihar, India. Forty-one groundwater samples were collected and analyzed for 14 physio-chemical parameters including pH, EC, TDS, hardness, major ions, fluor...
