Kueishantao, Taiwan

By ExploreNow Editor, on February 17th, 2012%

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 1785 ± 10 years
Summit Elevation: 401 m    1,316 feet
Latitude: 24.85°N   24°51’0″N
Longitude: 121.92°E   121°55’0″E

Kueishantao Island, whose summit is 401 m above sea level, is the southernmost of five small volcanic islands off the NE coast of Taiwan. Kueishantao, also known as Guieshan Island, consists of andesitic lava flows and volcaniclastic material. Kueishantao is the southwesternmost volcano along the axis of the Okinawa Trough back-arc basin that extends to the NE from Taiwan to Unzen volcano in Kyushu.

The SW tip of the Okinawa Trough extends past Kueishantao onto the Ilao Plain on the island of Taiwan. The island is known as “Turtle Mountain Island” due to its profile as seen from some points on the coast of Taiwan. Historical accounts during the time of King Qianlong of the Qing Dynasty (1775-1795 AD) noted the Guieshan mountain split open with a blood-red lava flow. Kueishantao displays vigorous active submarine fumaroles and solfataras that discolor seawater over wide areas.

Tatun Volcano Group, Taiwan

By ExploreNow Editor, on November 24th, 2011%

Volcano Type: Lava domes
Volcano Status: Radiocarbon
Last Known Eruption: 4100 BC ± 40 years
Summit Elevation: 1120 m   3,674 feet
Latitude: 25.17°N *   25°10’0″N
Longitude: 121.52°E   121°31’0″E

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 north 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 at the Tatun volcano group about 23,000 to 13,000 years ago, and a phreatic eruption assocciated 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.
