Seismic Mapping of India

Seismic Mapping of India Read about the Earthquake of India and then click here. A total of ~59% of the land mass of India (covering all states of India) is prone to earthquakes of different intensities. As per the seismic zoning map of the country, the total area is classified into four seismic zones. Zone V is seismically the most active region, while zone II is the least. Approximately, ~ 11% area of the country falls in zone V, ~18% in zone IV, ~ 30% in zone III and re

Intensity of cyclones in North Indian Ocean is increasing

Intensity of cyclones in North Indian Ocean is increasing First read the comprehensive topic of Cyclones and then read this news. The retention quality will increase exponentially. The intensity of severe cyclonic storms in the North Indian Ocean region has shown an increasing trend in the past four decades, says a recent study by Indian Scientists. The increasing intensity of severe cyclonic storms with major socioeconomic implications was due to atmospheric parameters like

Yaas Cyclone

Tropical Cyclones Yaas Definition of a Cyclone Cyclone refers to any spinning storm that rotates around a low-pressure center. The low-pressure centre is also referred to as the 'eye' of the storm, which is well known for being eerily calm compared with the areas under the spinning 'arms' of the storm. You could say that the eye is watching what's going on down below, so it needs a clear path, but the arms are where all the action happens because this is where the

DBT MOES Polar Research Centre

DBT MOES Polar Research Centre Department of Biotechnology signed a Memorandum of Understanding (MoU) With Ministry of Earth Sciences To Set up DBT MOES Polar Research Centre POLAR region encompassing the Antarctic, Arctic, Southern Ocean and the Himalayas being a unique ecosystem offers a huge amount of interest due to its extreme climate compare to the rest of the world. Although researchers across the globe have contributed to different areas of research, the POLAR region is yet kn

Chilika Lake was a part of the Bay of Bengal- Study shows

Chilika Lake was a part of the Bay of Bengal: Study According to a study by the National Institute of Oceanography(NIO), Chilika lake was once a part of the Bay of Bengal. Evidences- Archeological Studies: The marine archaeological studies clearly show that the Chilika once was a safe harbour for cargo ships going to Southeast Asia and other parts of the world. Palur Port: Greek geographer Claudius Ptolemy(150 CE) described Palur as an important port of Kalinga and

Non-uniformity of Himalayas foresees significantly large earthquake events

Non-uniformity of Himalayas foresees significantly large earthquake events Scientists have found that the Himalayas are not uniform and assume different physical and mechanical properties in different directions — a property present in crystals that is called ‘anisotropy’. This could result in significantly large earthquake events in the Himalayas. The north-west region of India, an area covering Garhwal and Himachal Pradesh, has been hit by four destructive moderate

US-Canada Heat Waves

While heatwaves are quite common during the summer months, the scorching heatwave hitting parts of western Canada and the US has been particularly devastating – with temperature records shattered and hundreds of people falling victim to the extreme heat. Canada broke its temperature record for a third consecutive day: recording a whopping 49.6°C on 29 June in Lytton, a village northeast of Vancouver, in British Columbia. The persistent heat over parts of western Canada and part

Impacts of Desert Dust Particles on Indian Summer Monsoon

A new study shows the impacts of desert dust coming from the West, Central, and East Asia in the Indian Summer Monsoon. Impact of Desert Dust Particles on Indian Summer Monsoon: Strong winds carry the dust particles from the Middle East into the atmosphere. Dust particles absorb solar radiation and become extremely hot. This causes heating of the atmosphere. Heat decreases the air pressure and changes wind circulation patterns. Further, it increases the moisture transport capa

Militarisation of the Arctic

Militarisation of the Arctic The Biden administration is leading a campaign against Russian attempts to assert authority over Arctic shipping and reintroduce a military dimension to discussions over international activity in the area. As Russia assumed the rotating chairmanship of the Arctic Council on Thursday, the U.S. rallied members to oppose Moscow’s plans to set maritime rules in the Northern Sea Route, which runs from Norway to Alaska, and its desire to resume military talks
