A lava flow in the 13th century, the Stampa eruption, meets the sea and cools into vesicular basalt. Gas bubbles, called vesicles, are trapped in the rock. The layer lies on an older formation and now forms a low cliff that is collapsed and eroded in places. The sea has undercut the Stampa layer and congelifraction ( frost shattering ) has created fractures along joints in the rock. The coastline here is subjected to extreme weather and tsunamis.
