Why parts of North India felt big tremors of a 6.5-magnitude earthquake in Afghanistan :
On March 22nd, 2023, parts of North India were hit by strong tremors of a 6.5-magnitude earthquake in Afghanistan. The quake, which struck at a depth of 147 km, was felt across several regions in India, including Delhi, Haryana, and Uttar Pradesh.
The reason for the tremors being felt in North India lies in the geological structure of the region. India lies in a seismically active zone, with the Himalayas forming a major part of this region. The Himalayan region is characterized by several active fault lines that are prone to frequent earthquakes. These fault lines are the result of the collision between the Indian and Eurasian tectonic plates.
The Eurasian plate, which extends from Europe to Asia, is moving in a northerly direction, while the Indian plate is moving towards the north-east. As the two plates collide, the Indian plate is being pushed underneath the Eurasian plate, resulting in the formation of the Himalayas. This collision causes immense pressure and strain in the region, leading to frequent earthquakes.
In the case of the recent earthquake in Afghanistan, the tremors were felt in North India due to the proximity of the region to the epicenter. The epicenter of the earthquake was located in the Hindu Kush mountain range in Afghanistan, which is situated close to the northern border of Pakistan. The seismic waves generated by the earthquake traveled through the earth's crust and were felt in North India.
Moreover, the geological structure of the region also played a role in the intensity of the tremors felt in North India. The seismic waves generated by the earthquake were amplified by the sedimentary basin in the region, which acted as a natural amplifier of seismic energy.
In conclusion, the recent earthquake in Afghanistan, which was felt in parts of North India, is a result of the seismically active zone in which the region is located. The collision between the Indian and Eurasian tectonic plates has led to the formation of several active fault lines in the region, which are prone to frequent earthquakes. While the tremors were felt across a large region, the geological structure of North India played a role in the intensity of the tremors felt in the area.
It is worth noting that earthquakes in the Himalayan region can be particularly devastating due to the high population density and poor infrastructure in the region. In 2015, a 7.8-magnitude earthquake in Nepal killed over 8,000 people and caused widespread damage to infrastructure and property.
As a result of the frequent earthquakes in the region, India has established a robust seismic monitoring network to detect and measure seismic activity. The network includes several seismological observatories, which monitor seismic activity in real-time and provide early warnings to minimize the impact of earthquakes.
Furthermore, efforts are also underway to improve building codes and retrofit existing buildings to withstand earthquakes in the region. The government has launched several initiatives to raise awareness among the public and promote earthquake-resistant construction practices.
Despite these efforts, earthquakes remain a major threat in the Himalayan region, and it is crucial for the government and the public to remain vigilant and prepared for future seismic activity.
In conclusion, the recent earthquake in Afghanistan, which was felt in parts of North India, is a reminder of the seismically active zone in which the region is located. While the geological structure of the region and proximity to the epicenter played a role in the intensity of the tremors, the impact of earthquakes in the region highlights the need for preparedness and building resilience to minimize the impact of seismic activity in the future.
