The Tatun (Datun) Volcanic Group (TVG) is a number of andesitic lava domes in the northern portion of the island of Taiwan. There are at least 20 volcanoes, the southernmost (and largest) of which are located only 15 km N of Taipei City. This puts over 5 million within 5 km of the field and nearly 8 million within 30 km.
