Question

Why does earthquake occur in subduction zone? (the area where subduction occur) ​​

Answer 1

Answer:

The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates.

Subduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. ... Earthquakes are caused by movement over an area of the plate interface called the seismogenic zone. This zone 'locks' between earthquakes, such that stress builds up.

Answer 2

Earthquakes occur in the subduction areas as the disjointed lithospheric plates go through the highest rate of vibrations due to their uncertainty.

Subduction Zones

• Subduction zones are places where the lithospheric plates ride one above the other. They are similar to the tectonic plates.
• They are not level and are unstable.
• They are mainly susceptible to natural disasters like earthquakes, volcanic eruptions, etc.

Earthquakes in the Subduction Zones

Since the lithospheric plates ride one above the other, they are prone to movements. These movements lead to tremors on the land surface that are termed earthquakes.
