The Bhagirathi Valley is investigated to understand the impact of various barrages and dams on natural river flow. The multiple barrages and dams in the valley (downstream of the Bhatwari Village) have obstructed/disrupted natural flow of the river which has adversely impacted geomorphological and ecological functions of the river.

Four geographical zones are defined along the trench that is formed due to the subduction of the Nazca Plate underneath the South American plate; they are denoted A, B, C and D from North to South; zones A, B, and D had a major earthquake after 2010 (Magnitude over 8.0), while zone C has not, thus offering a contrast for comparison. For each zone a sequence of intervals between consecutive seisms with magnitudes ≥ 3.0 is set up and then characterized by Shannon entropy and mutability.

Extreme slip at shallow depths on subduction zone faults is a primary contributor to tsunami generation by earthquakes.

The ~70 km-diameter Yarrabubba impact structure in Western Australia is regarded as among Earth’s oldest, but has hitherto lacked precise age constraints. Here we present U–Pb ages for impact-driven shock-recrystallised accessory minerals.

A fundamental feature of any Earthquake Early Warning System is the ability of rapidly broadcast earthquake information to a wide audience of potential end users and stakeholders, in an intuitive, customizable way. Smartphones and other mobile devices are nowadays continuously connected to the internet and represent

The September 2018, Mw 7.5 Sulawesi earthquake occurring on the Palu-Koro strike-slip fault system was followed by an unexpected localized tsunami. We show that direct earthquake-induced uplift and subsidence could have sourced the observed tsunami within Palu Bay.

Order of the National Green Tribunal in the matter of Aabhijeet Sharma Vs Union of India & Others dated 31/07/2019. The applications seek reconstitution of the Committee constituted by the Ministry of Environment, Forest and Climate Change (MoEF&CC) in pursuance of order of the Tribunal dated 16.10.2017 for Subansiri Lower Hydro Electric Project (SLHEP).

Background of the Case:

The present study outlines major concerns and potential environmental consequences of the proposed Pancheshwar high dam in Uttarakhand (Central Himalaya), India.

Order of the National Green Tribunal in the matter of Yogendra Mohan Sengupta Vs Union of India & Others dated 31/01/2019 regarding permission for expansion of Cancer Care Centre at Shimla by relaxing the directions of the judgment dated 16.11.2017 of the Tribunal prohibiting any new construction in ‘Core and Green/Forest area’ of Shimla in view of the impact of huge constructions already made affecting seismicity and environment.

Recent studies suggest that Antarctica has the potential to contribute up to ~15 m of sea-level rise over the next few centuries. The evolution of the Antarctic Ice Sheet is driven by a combination of climate forcing and non-climatic feedbacks.
