If a large shield volcano has a massive eruption, empties its magma chamber, and becomes dormant, several geological processes can shape the landform over time.
If a shield volcano goes dormant after a large eruption, it will go through transformative processes. Wind, water, and ice-driven erosion and weathering sculpt the slopes, creating valleys, and changing the original landform. As vegetation progressively takes over the area, it stabilizes the soil and promotes the growth of ecosystems.
The topography changes, revealing ridges, valleys, and other topographical features. The region's topography is continuously changing over time due to the possibility of secondary volcanic activity and ongoing geological events, even though the main volcano is still dormant.
