Healthy Elkhorn coral (Acropora palmata) near unpopulated Buck Island, U.S. Virgin Islands. Elkhorn coral is one of many important reef-building species that create 3D structure on the seafloor. Coral reef structure provides habitat for marine life and helps break up waves as they approach the coastline.

Coral reef structure provides habitat for marine life and helps break up waves as they approach the coastline.
These Elkhorn corals (Acropora palmata) near Buck Island, U.S. Virgin Islands have died and collapsed into rubble. As coral reef structure degrades, valuable habitat for marine life is lost and nearby coastlines become more susceptible to storms, waves and erosion.

Cliff erosion is a common storm-induced hazard along the West Coast. Two condemned apartment buildings along Esplanade Avenue in Pacifica, California are shown here before their demolition in 2016 and 2017.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Oregon Inlet, North Carolina. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach and inundated the low area in the backshore at Oregon Inlet (A, green box, blue arrows).
