the lidar image above shows the region around seattle, extending from the puget sound to the foothills of the cascades. overlaid in brown are landslides mapped by the washington state department of natural resources. note that most landslides in the seattle area occur near the coast along the puget sound and lake washington. (a) why are more landslides found along the coastline in seattle greater precipitation along the puget sound shorelines ? the climate of the puget sound is characterized by high amounts of rainfall. as such, increased pore water pressure is the predominant landslide triggering mechanism in the puget sound. however, 1965 was a particularly dry year, yet there was a higher than average number of landslides in the seattle area. (b) what was another possible trigger for these landslides more development of steep slopes in 1965 ? include answers to both question (a) and question (b) in your response.
