A tiny volcanic island resists typhoons better than continents

While continental shores often slowly surrender to the sea, the Dokdo islets are built from a rare volcanic recipe that makes them nearly indestructible. Formed 2.5 million years ago, these twin peaks are composed of 70 percent plagioclase, a crystal-heavy mineral that creates sheer, vertical cliffs. This geological armor is so dense it can withstand the relentless 10-meter-per-second winds of a Pacific typhoon without significant erosion.
