Delhi Earthquake Trembling was felt across Delhi and in the nearby regions of Noida and Gurugram as well on Friday late evening after two earthquakes hit Rohtak in Haryana in a span of an hour. There were no immediate reports of casualties or loss of property. The first quake was a medium intensity one of magnitude 4.6 had an epicenter in Rohtak in Haryana, said National Centre for Seismology. According to the NCS, the quake occurred at a depth of 5 km at 9.08 pm. shaking movement on Richter skell A second quake occurred within a span of one hour and was of lower intensity of magnitude 2.9 and occurred at the same location at 10 pm, the NCS said. Rohtak is situated nearly 60 km from Delhi. Delhi Earthquakes of less than five magnitudes are unlikely to cause large-scale damage, unless in case of weak or compromised structures. Delhi lies on Zone IV of the seismic map of India. Zones IV and V have a high probability of destruction. This is the third time trembling h...

Cyclone Amphan During 13 May 2020, an area of low pressure developed over the Southeastern Bay of Bengal about 600 km to the southeast of Chennai in the Indian state Tamilnadu The area of low pressure was located within a favorable environment for further development with good  warm sea surface temperatures, and low verticals wind share Over the next couple of days, the system became more marked as it gradually consolidated further, with bands of deep atmospheric pressure wrapping into the system's low-level center. During 16 May, the (IMD) reported that the area of low pressure had developed into a depression and designated it as while it was located about 1,100 km  to the south of Paradip in the Indian state of Odisha. Moving northwards, the depression continually organized and became a cyclonic storm a few hours later, receiving the name Cyclone  Amphan. Intensification was temporarily impeded as moderate disru...

Cyclone Formation          A tropical cyclone can be regarded as a large and tall cylinder of clouds containing enormous amounts of water and packing heavy winds. It is like a giant heat engine fuelled by the release of latent heat due to condensation ty of water vapor drawn from the warm sea surface waters. The released latent heat warms u the air, making the air lighter in that column which more warm and moist air to rise and consequently more release of latent heat over the same place. Thus air rushes in from all sides and rises vertically up creating a rotating vortex. If the process continues for a longer pressure fall in that place could be very much below normal resulting in further growth of the tropical cyclone and strengthening the winds. To get this engine started a large quantity of warm and moist air is required. Steady supply is needed to keep the process going. Scientific studies indicate that this is possible under certain conditi...

Cyclone in India Over the globe, about 70-90 tropical cyclones form every year and about 2/3 of these reach the very severe stage. Most of the cyclone formation takes place between 20° N to 20° S but no formation occurs within about 2-1/2 latitude of the Equator. About Two-thirds of all cyclones occur in the Northern Hemisphere and twice as many tropical cyclones occur in the Eastern as compared to the Western Hemisphere. These differences are due to the absence of tropical cyclones in the South Atlantic and the Eastern South Pacific Oceans. Tropical Cyclones are seasonal phenomena and most basins have a maximum frequency of formation during the summer to early fall period with the peak occurring during January to March in the Southern Hemisphere and July to September in the Northern Hemisphere with the exception of North Indian Ocean where the frequency of tropical cyclone is bi-modal in character with the primary peak in November and secondary peak in May. A developing cyclo...

Cyclone Among the extreme weather events, Cyclones also termed as Tropical Cyclones (TCs) are by far the most devastating, both by causing loss of human lives as well as economic losses. The name 'cyclone' which means "coils of a snake" in Greek was given to the revolving storms in the North Indian Ocean by Henry Piddington who was the president of Marine court in Calcutta from 1839 to 1856 in the mid-19th century, and the was the first to coin this word. These are called Tropical Cyclones because they form over the warm waters of tropical oceans. Intense low-pressure areas forming over higher latitudes either over the land or over the ocean are known as Extra-Tropical Cyclone. However, but for the similarity of name, there are large differences between the two types of weather systems. As those occurring in the Indian Ocean called Cyclone, those occurring in the  Philippines and China Sea  are Called Typhoons, and those occurring in the Caribbean areas  are ca...
