Tatun Volcanic Group
The Tatun Volcanic Group constitutes a group of volcanoes located in northern Taiwan. It is located 15 km north of Taipei, and lies to the west of Keelung. It just adjoins the northern coast of the Taiwan island. The volcanic group was a result of episodic volcanism between 2.8 and 0.2 Ma. As of 2005, some geothermal activity was occurring and gas fumaroles were active among these volcanoes. Observations of the Tatun Volcanic Group suggest that magma chambers probably still exist under the land surface of northern Taiwan. The last eruption occurred in the year 648.
In 2002 it was listed as a potential World Heritage Site.
History
The north of the island is where evidence of volcanic activity is most obvious. In the early 20th century, the North Range of hills, also called Daitonzan from Japanese or Twa-tun from Hokkien, was recognized as having an abundance of sulfur deposits. There were three craters in the North Range between Tamsui and Kimpauli. The North hill crater, over in diameter and about deep, was the most extensive and was sometimes filled with water.Volcanic edifices
