New Delhi (JNN). The earthquake in the Delhi-NCR region about ten times in the last one and a half months has been a big question for everyone. Because of them, everyone is in panic and question is arising in their mind that whether they feel that it is a disaster or not. This question is not baseless. For those who know that Delhi is in a very sensitive area of earthquake, these questions can definitely be troublesome. To get answers to these questions, Kamal Kant Verma from Jagran.com spoke to BR Gansal, Scientist G of Scientist G, Ministry of Earth Science.
No need to fear
During this conversation, Dr. Bansal dismissed the speculation in which the frequent earthquakes are being called as the impact of a major earthquake. According to him, all the landslides that have come to the Delhi-NCR area so far have been reduced significantly on the visitor scale. Apart from this, these earthquakes have not come to any place and come at different places. Their center is different and their source zone was also different. This is the reason that they do not consider these earthquakes to be the result of any major earthquake. According to him, such earthquakes have been coming before. Earthquake activity has intensified in Delhi in the last ten years.

Earthquake incidence has increased in ten years
According to him, more than 200-300 earthquakes have been recorded during this period, but all of them were of very low magnitude. There were only two or three of them whose magnitudes were around 5. He clearly said that there is no need to be afraid of frequent earthquakes. But as far as its prior information is concerned, these are extremely difficult to do. However, during the Bhuj earthquake in Gujarat, it was seen that there were some tremors before the tremendous earthquake. He says that the National Center for Seismology is also to be consulted by other experts and the result has been that there is no need to be afraid of frequent low-intensity earthquakes.
Delhi comes in seismic zone-4
Let us tell you that on the basis of earthquake intensity, the whole country is divided into four zones. Delhi falls in Zone-4 based on the seismogenic map. According to Dr. Bansal, an earthquake of magnitude 8 is expected in such a zone. But this intensity does not mean magnitude. According to him, there is no change in magnitude while the intensity is affected by the earthquake. Intensity of 8 has been kept in this zone because which is the area of our Himalayas, there are big source zones, they can cause big earthquakes. Due to these source zones, the intensity of earthquake in Delhi can be 8.
Question on some major earthquakes in history
Bansal says that even if there is an earthquake of more than 6 magnitudes at these places, its intensity may be 8 in Delhi. As far as the type of earthquake in Delhi is concerned, the earthquakes that have come in history were not even capable of that type. The 1803 earthquake in Mathura was reported to be over 6 magnitudes. But experts believe that it was from the Garhwal region. Some other major earthquakes in history are also under question. At the same time, all these are before that technology, since in India they are being measured on the basis of technology.
Not believable statistics
Now all records and data are analyzed on the basis of technology and after that it is decided what its actual magnitude was. He says that as far as the history of the great earthquake in India is concerned, the researchers at that time had tried to convert the intensity of what they felt into Magnitude. This is the reason why their data cannot be believed.
