The Tatun (Datun) volcano group consists predominately of a series of andesitic lava domes in the northernmost part of Taiwan. About 20 volcanoes, the southernmost of which is only 15 km N of the capital city of Taipei, are included in the Tatun group, which was constructed along E-W and NE-SW trending ridges. The highest and youngest volcano is the 1120-m-high Cising (Chisingshan) lava dome. Several magmatic eruptions took place in the group about 23,000 to 13,000 years ago, and a phreatic eruption associated with collapse of the lava dome, possibly closely following lava effusion, took place about 6000 years ago. Hot springs, fumaroles, and solfataras are found over wide areas along a zone parallel to the SW-NE-trending Chinshan fault and extending to the NE coast of Taiwan, and extensive geothermal exploration has occurred at the Daiton geothermal area.

The Tatun (Datun) volcano group forms the northernmost part of Taiwan, north of the capital city of Taipei (lower left). About 20 andesitic lava domes are included in the Tatun group. The two small narrow peninsulas west of the top center of this NASA Landsat image mosaic (with north to the top) are formed by lava flows from the Tatun group. The latest eruptions in the group are of late Pleistocene and mid-Holocene age, but hot springs, fumaroles, and solfataras are found over wide areas, and extensive geothermal exploration has occurred.

Lava domes of the Tatun (Datun) volcano group rises to the NE beyond Taipei, the capital city of Taiwan. About 20 andesitic lava domes are included in the Tatun group. The latest eruptions in the group are of late Pleistocene and mid-Holocene age. Hot springs, fumaroles, and solfataras are found over wide areas, and extensive geothermal exploration has occurred.

A phreatic eruption from a fissure on the west side of Cisingshan lava dome, seen from the west, took place at the time of the Cisingshan debris avalanche about 6000 years ago. The fissures contain small funnel-shaped craters that were the sources of explosive breccias several hundred meters wide and several meters thick that were considered to possibly be related to lithostatic unloading of the youngest lava flows of Cisingshan, which may have occurred only a few years before the collapse.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
