Hey guys.After my trials and errors i have come up with an interesting topic about how are volcanoes and earthquakes related.
How are volcanoes and earthquakes related?
Some, but not all, earthquakes are related to volcanoes. For example, most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma.
Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again. Every time the rock cracks it makes a small earthquake. These earthquakes are usually too weak to be felt but can be detected and recorded by sensitive instruments. Once the plumbing system of the volcano is open and magma is flowing through it, constant earthquake waves, called harmonic tremor, are recorded but not felt.Earthquakes and volcanoes are natural phenomena resulting from the plate tectonics. In general, a volcanic eruption is accompanied by earthquakes.
The close relationship between temblors and volcanic outbursts is evident from the maps depicting the locations prone to both these phenomena. If you compare the maps that illustrate earthquake zones and volcanic zones, you will find them matching each other. This is because the main theory behind both these natural calamities lies in the plate tectonics.
The planet Earth comprises irregular-shaped and varying-sized plates, which constantly move at different speeds. To be precise, the plates drift over the mantle layer of the Earth. Consequently, magma is generated along the plate boundaries.
When the plates collide, move apart, or slide each other, it leads to generation and accumulation of pressure (strain), which when released causes earthquakes. The strongest earthquakes are manifested during the plate collision, while the slowest earthquakes are observed when plates move apart from each other.In addition, both activities occur within a plate, which are referred to as interpolate earthquakes and volcanoes, respectively. It is estimated that about 10 percent of earthquakes are of this type.
