Unravelling the earth’s deep secrets, A unique Indian laboratory in Karad

The Borehole Geophysics Research Laboratory (BGRL) situated in Karad, Maharashtra is a first of a kind and the only laboratory in India that has been helping scientists to study earth’s deep secrets for nearly five years now (Fig 1). Set up in 2014, BGRL has enabled scientists to get access to a variety of samples […]

UNESCO adds 15 new Geoparks, not a single from India

UNESCO’s executive board in its July 2020 meeting designated 15 new areas as new geoparks. Geoparks are single and unified geographical areas where sites and landscapes of international geological significance are managed with a holistic approach (UNESCO 2020). With these 15 newly designated areas, the total number of sites in the Global UNESCO Geoparks Network […]

Ozone Loss

Evidences of Ozone Recovery

The ozone loss process in the stratosphere is relatively well understood and much of the loss is driven by the chemical cycles involving chlorine and bromine compounds, whose abundance peaked around 2000 in the polar stratosphere. With the abatement of atmospheric loading of ozone depleting substances (ODSs) due to the implementation of Montreal Protocol, the […]

Soil Erosion

Soil Erosion and Conservation in India

Soil erosion in India Excessive soil erosion in India combined with consequent high rate of sedimentation in reservoirs and decreased soil fertility has led to grave environmental problems. Soil erosion mostly affects practically all kinds of lands such as the forest lands, agricultural lands, arid and semi-arid lands, surface mines, roads, construction sites, coastal areas […]

What is soil liquefaction? Causes, effects and measures

“A Phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a  liquid” is called Soil Liquefaction (Hazen,1918). There are two types of soil liquefaction. 1) Flow liquefaction 2) Cyclic Mobility […]

Active Volcanoes Around the world

Volcanoes around the world – what is likely to become active

A volcano is the emission of lava, ash and gases from deep under the earth’s surface through a crack on the surface of the earth. According to the Plate Tectonic Theory, the earth’s lithosphere (which includes the crust and upper mantle) is made of tectonic plates. These tectonic plates meet at three different kinds of […]

Glacial Landforms

Glacial Landforms in Relation to the Himalayas

Glaciers are represented by the flowing movement of a thick mass of ice and form as a result of the compaction or recrystallization of snow. Glaciers occur in areas whose climate favours the seasonal accumulation of snow in greater volumes than seasonal ablation. Here the seasonal accumulation of snow outpaces seasonal ablation that occurs due […]
