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, when the magma reaches the surface it creates volcanoes. 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 leading to formation of massive waves creating trembling on the earth’s surface. Thus, volcanic eruptions can cause earthquakes because of the massive amount of energy that is released during an eruption.
