Answer
Indonesia experiences frequent volcanic eruptions because it lies along the Pacific "Ring of Fire"—a zone of intense seismic and volcanic activity surrounding the Pacific Ocean. This region is formed by multiple tectonic plate boundaries, making it one of the most volcanically active areas in the world, with over 120 active volcanoes across the Indonesian archipelago.
When a volcanic eruption occurs under the sea, it can cause a sudden displacement of a large volume of water. This disturbance creates powerful sea waves that travel rapidly across the ocean, known as tsunamis. Thus, underwater volcanic activity can directly trigger a tsunami.
