GEOLOGY

Detailed explanation-1: -We can deduce that volcanoes and earthquakes are caused by tectonic plate movements, they both pose a significant danger to humans, and result in deadly secondary effects like tsunamis.

Detailed explanation-2: -Unlike most volcanoes and earthquakes, tsunamis are not direct consequences of plate tectonics. The most common tsunami trigger is submarine earthquakes, but they can also be set off by a volcanic eruption under, or next to, the sea. Thus volcanoes, earthquakes and tsunamis are part of the same story.

Detailed explanation-3: -Volcanic eruptions can profoundly change the landscape, initially through both destructive (flank failure and caldera formation) and constructive (lava flows, domes, and pyroclastic deposits) processes, which destroy vegetation and change the physical nature of the surface (e.g., porosity, permeability, and chemistry).

Detailed explanation-4: -Earthquake. The surface of the Earth is made up of tectonic plates that lie beneath both the land and oceans of our planet. The movements of these plates can build mountains or cause volcanoes to erupt. The clash of these plates can also cause violent earthquakes, where Earth’s surface shakes.

Detailed explanation-5: -Volcanically-caused long period earthquakes are produced by vibrations generated by the movement of magma or other fluids within the volcano. Pressure within the system increases and the surrounding rock fails, creating small earthquakes.
