Natural disasters such as earthquakes and tsunamis can have significant impacts on coastal landscapes and ecosystems. These events can reshape the coastline by altering landforms, sediment distribution, and elevations. They can also create new habitats or destroy existing ones, affecting the balance of ecosystems and biodiversity. Additionally, the force of tsunamis can carry sediments and debris inland, influencing the composition and structure of coastal ecosystems. Overall, natural disasters play a crucial role in shaping coastal environments and can lead to both short-term disruptions and long-term changes in coastal landscapes and ecosystems.
