Tongpan Island Lotus Seat Introduction
The southwestern coastline of Tongpan Island features a marine erosion platform, also known as a wave-cut platform or wave-eroded shelf. As the name suggests, the relentless waves erode the sea cliffs, causing them to gradually recede and forming a flat rock platform at nearly the same height as the sea surface. On this marine erosion platform, there is a structure known as the Lotus Seat, which is actually a formation of a submerged volcanic crater. Due to constant erosion from the surrounding seawater, it has a concave shape, with only a small hill rising in the center, resembling a lotus flower from a distance, hence its name. Locals also refer to it as "Lotus Platform." The outer ring of the Lotus Seat is surrounded by basalt, while inside, there is seawater left from high tide and some mottled marks of basalt eroded by seawater. When the tide recedes and the water withdraws, the entire Lotus Seat is revealed, akin to a lotus flower rising from the water. Coupled with the evening glow of the sunset, it truly creates an illusion of being in a fairyland.
