Hua Yu Island Introduction
The geological composition of the Penghu Islands consists primarily of basalt, with the exception of Huayu Island, which is made up of andesite. Andesite is a type of volcanic rock formed from magma that cools quickly, characterized by high viscosity and slow flow. It typically accumulates into conical shapes near volcanic craters, unlike the blocky terrain formed by basalt. Huayu Island was formed approximately 65 million years ago and is the oldest and westernmost island of Penghu. Located northwest of Wang-an, the island is home to nearly a hundred species of native plants, which is why it has been named Huayu. Currently, the population is just over a hundred, as the area is abundant in fishery resources due to the convergence point of the Kuroshio Current and the Taiwan Current, and most residents engage in fishing for their livelihood. The highest point on the island is Yandun Mountain, at an elevation of 53 meters, located in the eastern part of the island. On the summit of the western part of the island stands the Huayu Lighthouse, which has a pure white tower constructed of reinforced concrete. It is the westernmost lighthouse in Taiwan and serves as an important landmark for Huayu. On the southeastern reefs, there are left footprints of the legendary Lü Dongbin's "immortal footprints," which pair with the right footprint on Tian Tai Mountain of Wang-an Island, but these can only be seen during low tide!
