What is the relationship between volcanoes, earthquakes, and tsunamis in asia? how do seismic events like earthquakes cause tsunamis?

    Volcanoes and earthquakes are closely linked. Both result from the movement of tectonic plates that is constantly changing the surface of the earth. In addition, earthquakes give clues that a volcano may be on its way to an eruption.

    In the case of an earthquake that precedes an eruption, the main reason why it occurs is the moving magma.

    Volcanic activity can cause tsunamis due to one or a combination of several factors: underwater explosions, pyroclastic flows (gas, ash and rock currents) and volcanic landslides.

    But the main factor for tsunami formation is tectonic activity. A shock zone or encounter between two tectonic plates is a geologically very unstable area, providing the emergence of eventual earthquakes resulting from the release of accumulated energy at the points of contact between them. When this occurs in the ocean, there is an uplift of the oceanic waters, which agitate and are capable of generating very strong waves, the tsunamis.
