Formation of the island of Taiwan
Roughly 70 million years ago, the Paleo-Pacific plate and the Eurasian plate came together to cause a diastrophism, in turn triggering the “Nanao Orogeny”, which raised the stratum to form the island of Taiwan. Subsequently, when this process ended and the plates expanded, old Taiwan island gradually began to sink. Several million years ago, when the Eurasian plate collided with the Philippine sea plate, it triggered the “Penglai Orogeny”, and the island of Taiwan was raised once again. Through the forces of nature, the modern island of Taiwan gradually took shape.
