Tatun Volcanoes (), a
group of
volcanoes located in northern
Taiwan, is located 15 km north of
Taipei, and lies to the west of
Keelung
Keelung () or Jilong () (; Hokkien POJ: '), officially known as Keelung City, is a major port city situated in the northeastern part of Taiwan. The city is a part of the Taipei–Keelung metropolitan area, along with its neighbors, New Taipe ...
. It just adjoins the northern coast of the Taiwan island. The volcano 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 on Tatun Volcano Group suggest that
magma chambers probably still exist under the land surface of northern Taiwan.
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 (approx. modern-day
Jinshan). The North hill crater, over in diameter and about deep, was the most extensive and was sometimes filled with water.
