Birendranagar, nepal, was struck by an earthquake of a magnitude of 6.0, according to the European-Mediterranean Seismological Centre (EMSC). At a depth of 35 km, the earthquake struck. There have been more earthquakes in delhi NCR recently than ever before, but why do they occur so regularly in this area?

Tremors brought on by the movement of the tectonic plates inside the earth are what produce an earthquake. These plates are found inside the crust, which is the earth's topmost layer. An earthquake is the result of two blocks of the earth's surface moving against one another.

The "focus," or center of the Earth's crust, is the source of an earthquake.

In northern india, there are the Himalayas. The himalayas were formed as the indian plate migrated in the direction of the Nepalese plate.

Between North and Northeast india are the Himalayas. Since these parts of india and nepal are situated on the margins (fault zones) of two enormous tectonic plates, there are many earthquakes in these areas. Both nations become earthquake-prone due to the collision of the two plates.

According to the indian government, earthquakes of varying intensities can occur across around 59% of India's landmass, which includes all of its states.

The entire region is divided into four seismic zones according to India's seismic zoning chart. Seismically, zone II is the least active zone, and zone v is the most active. Zone 5 has eight states and Union Territories that are susceptible to the strongest earthquakes. Zone IV includes the Delhi-NCR area.

Percentage of India’s total landmass area in Earthquake Seismic Zone:

Zone V: 11% (most active)
Zone IV: 18%
Zone III: 30%
Zone II: 41% (least active)
