Question

Give geographical reason.

Volcanic eruptions can cause earthquakes. 

Answer 1

1. Volcanic eruptions occur when either plates sink below another plate (subduction), heating and creating magma, or plates pull apart, allowing magma to rise to the surface. In both these conditions, magma creates volcanoes when it reaches the surface.
2. Thus, most of the volcanoes are found on the plate boundaries. An earthquake occurs when the tension in the normal movements within the earth’s crust increases, forming massive waves creating trembling on the earth’s surface.
3. Thus, volcanic eruptions can cause earthquakes because of the massive amount of energy that is released during an eruption.
