Earthquakes refer to shaking or trembling of the Earth's crust as a result of abrupt release of energy. They are basically seismic waves, generated by the natural phenomena or at times, man-made events. Volcanoes, on the other hand, are openings in the Earth's crust from which hot gases and molten rock materials are ejected on the surface of the Earth.

Earthquakes and volcanoes are related to each other. In fact, earthquakes usually accompany a volcanic eruption. Similarly, unusual earthquakes can lead to volcanic eruptions. Before discussing about the relationship between earthquakes and volcanoes, let's take a brief look at each of them.


Earthquakes, as mentioned earlier, are caused due to sudden release of pressures that has been accumulated over a period of time. The generated seismic is measured with the help of seismometer in order to indicate the intensity or size of the earthquake.

The earthquake size is represented by moment magnitude scale (MMS); a magnitude of 3 or lower is undetectable, whereas a magnitude equal to or greater than 7 causes maximum damage to life and property. The underground point where the earthquake originates is called the hypocenter or focus. Epicenter refers to the point on the Earth's surface, which is exactly above the hypocenter.


Volcanic eruptions that involve extrusion of magma usually form mountains or mountain-like landscapes after the ejected materials cool down. They can occur in any part of the earth's surface, either in land or seas and oceans. Volcanoes are classified into active (eruptive), dormant (presently not active) and extinct (not eruptive) types, based on the activeness of a particular volcano. They are further classified into six different types - shield, cinder, submarine, subglacial, stratovolcano and supervolcano, depending upon the mode of ejection and other features.
