Tectonics, Earthquakes, and Volcanoes
Both volcanoes and earthquakes occur due to movement of the Earth’s tectonic plates. They are both caused by the heat and energy releasing from the Earth’s core. Earthquakes can trigger volcanic eruptions through severe movement of tectonic plates. Similarly, volcanoes can trigger earthquakes through the movement of magma within a volcano. Therefore, one aspect of how are volcanoes and earthquakes interrelated is the cyclical relationship where earthquakes cause volcanic eruptions and magma movement causes earthquakes.
