Tsunamis and coastal erosion also pose significant threats, with poor land use exacerbating these issues. In Pacifica, severe erosion led to the condemnation and demolition of homes along Esplanade Ave, resulting in evacuations of low-income residents.
If we are going to attempt to assess the risk of a tsunami at some particular place on the planet, we must first understand how to make a tsunami. Earthquakes and volcanoes generate the great majority...If we are going to attempt to assess the risk of a tsunami at some particular place on the planet, we must first understand how to make a tsunami. Earthquakes and volcanoes generate the great majority of tsunamis, and the theory of plate tectonics explains the cause of earthquakes and volcanoes. So, we'll start with the world's briefest review of plate tectonics.
