How do you think knowledge of earth's structure provides insight into how and why these natural events happen?

Knowledge of the structure of the earth can provide insight into natural events such as earthquakes, volcanoes, landslides e.t.c. The Earth's crust is divided into tectonic plates. The boundaries where these plates interact with each other generates earthquake and volcanic activity. This knowledge has helped humans to map out and predict where and to some extent, when,  these events will occur.
