Kashmir, Western and Central Himalayas, the whole of North-East, Rann of Kutch, Rajasthan and Indo-Gangetic plane are weak zones.
Earthquakes are caused by the movement of tectonic plates, the boundaries of the plates are the weak zones where earthquakes are more likely to occur. The weak zones are also known as seismic or fault zones.
, western and central Himalayas, the whole of North-East and Rann of Kutch.
The weak zones along the boundaries of the plate where earthquakes are more likely to occur known as seismic zones.
Delhi is prone to earthquakes because it is sitting on three major fault lines. “Delhi has a few fault lines. This means there are some junctions of plates, in and around Delhi-NCR. The Delhi-Moradabad fault line is a major fault line.
The city of Mumbai has a long history of experiencing earthquakes, with over 25 recorded events of magnitude 4 or greater in the last 400 years.
Zone 5. Zone 5 covers the areas with the highest risk of suffering earthquakes of intensity MSK IX or more significantly. The IS code assigns a zone factor of 0.36 for Zone 5. Structural designers use this factor for the earthquake-resistant design of structures in Zone 5.
Looking at the zonal map of India, you can check that India is divided into six zones namely North Zone, South Zone, East Zone, West Zone, Central Zone and North East Zone. All these zones include 28 states and 8 union territories. Each zone is comprised of certain number of states and union territories.
The earthquake belt in India is mainly confined to the Himalayan region and the Ganga-Brahmaputra valley. About two- thirds of India is earthquake prone. SSC CPO SI Tier II Exam Date Out on 29th March 2023!
In simple words, the tremors in the Indian subcontinent occur when the Indian plate collides with the Eurasian plate along the faultlines present near the Hindu Kush region.
In July 2021, minister of state for Science & Technology and Earth Sciences, Jitendra Singh informed the Lok Sabha "that considering the recorded history of earthquakes in the country, a total of 59% of the land mass of India is prone to earthquakes of different intensities".
The strongest earthquake in India happened on 08/15/1950 in the India-China region with a magnitude of 8.6 on the Richter scale. The shifting of tectonic plates in a depth of 30 km resulted in 1530 deaths.
The zone of weakness concept implies that there exist within the earth's crust relatively weak zones which when differentially stressed will fail more readily than will the surrounding rock. Such zones are often inferred to determine the extent, orientation and style of younger deformation.
The point where an earthquake starts is termed the focus or hypocentre and may be many kilometres deep within the earth. The point at the surface directly above the focus is called the earthquake epicentre.
Save this answer. Show activity on this post. The region where the Earth's internal magnetic field is weakest is known as the South Atlantic Anomaly (SAA).
India is divided into four zones based on the lifestyle of people. These are Western India, Eastern India, Northern India and Southern India.
... divided India into five major regions like northern, western, central, southern and eastern states according to Table 1.
The study revealed that global warming is a major cause of the increase in the sea level and Chennai and Kolkata are at greater risk in India. A new study on climate change has revealed that Chennai and Kolkata are at high risk if the sea level rises.
Thirteen coastal states and Union Territories (UTs) in the country are affected by tropical cyclones. Four states (Tamil Nadu, Andhra Pradesh, Orissa and West Bengal) and one UT (Puducherry) on the east coast and one state (Gujarat) on the west coast are more vulnerable to cyclone hazards.
Very High Damage Earthquake Risk Zone in India include the north-eastern regions, areas to the north of Darbhanga and Araria along the Indo-Nepal border in Bihar, Uttarakhand, Western Himachal Pradesh (around Dharamshala) and Kashmir Valley in the Himalayan region, and the Kachchh (Gujarat).
The study says sea levels rose by 4.5 mm a year between 2013 and 2022, over three times the rate between 1901 and 1971. India's financial capital Mumbai is among several cities across the globe that would be most affected due to rising sea levels, according to a report by the World Meteorological Organization (WMO).
Being a coastal city, Mumbai is also at risk of tsunamis, with the west coast being more vulnerable because of its high population density, while the east coast, with its mangroves and salt pans, is considered safer.
