Efects of Killari earthquake on the paleo‑channel of Tirna River Basin from Central India using anisotropy of magnetic susceptibility

Lakshmi, B.V.; Deenadayalan, K.; Gawali, Praveen B.; Misra, Saumitra (2020)

The Killari Earthquake (Moment magnitude 6.1) of September 30, 1993, occurred in the state of Maharashtra, India, has an epicenter (18°03′ N, 76°33′ E) located at ~ 40 km SSW of Killari Town. The ~ 125 km long basin of ...
Magnetic field measurements from Rome during the August–September 1859 storms

Blake, Seán P.; Pulkkinen, Antti; Schuck, Peter W.; Nevanlinna, Heikki; Reale, Oreste; Veenadhari, Bhaskara; Mukherjee, Shyamoli (2020)

The geomagnetic storm (or “Carrington event”) of 1–2 September 1859 is one of the largest geomagnetic disturbances on record. At the time, it caused widespread disruption to telegraph systems and was accompanied by aurorae ...
Rock-magnetic and archaeomagnetic investigations on archaeological artefacts from Maharashtra, India

Deenadayalan, K.; Gawali, P.B.; Lakshmi, B.V.; Rai, Manish (2020)

Archaeointensity and rock-magnetic studies were undertaken on 49 baked clay artefacts from four archaeological sites (Ter, Junnar, Nalasopara and Kanheri) in Maharashtra, India. Rock-magnetic properties, including bulk ...
The Role of Telluric (TE) and Magnetotelluric MT) Methods in the Exploration of deep Sedimentary Basins

Arora, B.R. (1995)

After a methodical overview of the magnetotelluric and telluric methods, the paper with the help of test example from the Pannonion basin (Hungary) illustrates the effectiveness of a combined telluric and magnetotelluric ...
Modelling of a fault in Indo-Suture Zone of Ladakh Region

Reddy, C.D.; Singh, Sumendra (1995)

Magnetic field is measured along the Keylong-Leh profile. This profile is approximately aligned at right angles to the main structural trend of the Himalaya and traverses across several prominent thrust zones of middle ...
Two dimensional modelling of electrical resistivity imaging data for assessment of saline water ingress in coastal aquifers of Sindhudurg district, Maharashtra, India

Gupta, Gautam; Khan, Tahama; Erram, Vinit C. (2020)

In coastal regions, the ingress of saline water into fresh water aquifers is a threatening phenomenon. The present study using electrical resistivity imaging in parts of Sindhudurg district in coastal Maharashtra, India ...
Lacustrine record of high magnitude flood events and climate variability during mid to late Holocene in the semiarid alluvial plains, western India

Basavaiah, N. (2020)

Long-term data on flooding events are necessary for understanding the flood frequency and magnitude variations, but the available instrumental records span only a few decades. Recently, lake sediment sequences have emerged ...
Surface deformation and influence of hydrological mass over Himalaya and North India revealed from a decade of continuous GPS and GRACE observations

Sunil, P. S.; Vijay Kumar, K; Ponraj, M.; Amrithraj, S.; Reddy, C.D.; Ramesh, D.S. (2020)

The India‐Eurasia collision, driven by tectonic forcing, is modulated by nontectonic forcing allied to seasonal variations in the neighboring regions. To decipher the ground deformation in response to hydrological mass ...
Nature of Cretaceous dolerite dikes with two distinct: constraints on their linkage to mantle plumes and large igneous provinces from 40Ar/39Ar geochronology and geochemistry

Sinha, Anup K. (2019)

Two distinct sets of Cretaceous dolerite dikes intrude the Chhotanagpur gneissic complex of eastern India, mostly within the Damodar Valley Gondwanan sedimentary basins. One dike set trends NNE to ENE, whereas the other ...
