What geological feature is located below an active volcano

The geological features that are usually present below an active volcano are as follow-

1) Mantle plume - This is the region containing a huge concentration of magma rising from the mantle-core boundary. This exerts huge pressure towards the surface of the earth thereby lifting the land and subsequently forms a volcano.

2) Magma chamber - These are chambers that are comprised of magma bodies and with the increasing pressure and temperature, they tend to rise up and form volcanoes.

3) D (i) ke - This are vein-like structures within which the magma moves upward with increasing force. They cross-cuts the country rocks.

4) Sills - This is a parallel vein-like structure along which magma flows and they are parallel to the country rocks. They are not that frequently found like d (i) kes.

Below an active volcano lies magma chamber. Magma is the liquid which makes the lava. It's located within the crust of the earth.

Explanation:

Magma chambers lies within the crust of the earth. Volcano is made up of magma which has come in contact with water. Upon contact with water, it erupts.

Once the volcano erupts it can destroy all forms of life surrounding it. The parts where the lava has fallen are no more capable of inhibiting.
