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.

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 has been felt in Delhi-NCR in the month of May and the fifth time in the last two months.
People of Delhi already facing the dreadful scenario of coronavirus and increasing numbers of patients in the region and maintaining social distancing and this earthquake creat panic in people's minds.

Why Earthquake Occurring in Delhi

Delhi comes under the Zone-IV, where highest damage is possible due to earthquakes.
The entire Himalayan seismic zone is vulnerable to strong earthquakes. The Indian tectonic plate is continuously driving into the Eurasian plates around this region at a speed of 44 mm/year. Due to this motion of tectonic plates, stress builds up, and the earthquakes are triggered to release tension

Many parts of north, east and northeastern India are at constant risk of strong earthquakes due to this phenomenon. The maximum risk areas for high-intensity earthquakes are classified as Zone-V in India. The zone broadly comprises entire northeastern India, parts of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Rann of Kutch in Gujarat, parts of North Bihar and Andaman & Nicobar Islands. The long-term seismological analysis in the region shows that the amount of energy getting accumulated in the subduction zones is not equally dissipated through the small and moderate earthquakes that we are seeing right now. The energy has been building up, and the only relief is a strong earthquake. Consequently, an earthquake of magnitude higher than eight has been projected in the Himalayan seismic zone. To compare, the Nepal earthquake of 2015 was of magnitude 7.8, and it claimed over 8,800 lives. Scientists, therefore, urge the people and authorities to be prepared by strict adherence to the building codes.
As they say, earthquakes do not kill people; buildings do!
Subduction Zone
When two tectonic plates collide each other than always heavier plate slide beneath the litter plate. India and Eurasia collided some 90 million years ago, as Indian plate is heavier than Eurasian the continental crust of the Indian tectonic plate was forced down under the Eurasian plate, sinking down into the Earth's mantle to a depth of at least 200 km kilometers. Delhi earthquake occurring due to being on the subduction zone.

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 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...

Cyclone In India

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...
