Earthquakes can have several impacts on landscapes. Some of the common effects include ground shaking which can cause landslides, ground ruptures, and the formation of new landforms such as fault scarps and fissures. Earthquakes can also trigger soil liquefaction, where saturated soil behaves like a liquid, leading to ground subsidence and a change in the landscape's topography. Additionally, earthquakes can alter rivers and streams, create new water bodies, and even change the course of existing waterways. Overall, earthquakes have the potential to significantly reshape and transform landscapes.
