Its not as if, Kato laughs, America doesnt have the know-how or technology to go a more structurally-based route. We have some national parks where were trying not to use the concrete sea walls or anything like that in order to preserve the scenery. Efforts have been made to shape seawalls and sunken piers to make them into appropriate habitats. The combined effects of elevated wave energy, water levels and directional shifts common during El Nio events have historically resulted in severe coastal erosion along the North American west . Eng.

L. et al. ), and the litho-sphere (topography, soil quality, groundwater, surface water, etc.) On the basis of more than 83,000 beach transects covering 8,300km of sandy coastline, we find that approximately one-third of all transects experience significant erosion during El Nio phases. That means domestic areas arent as prone to the type of seismic activity that propagate earthquakes and tsunamis.
