About Pengchiahsu
Pengchiahsu is a stratovolcano rising to 120 meters (394 feet) in Taiwan's Western Pacific Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Pengchiahsu is located in Taiwan, within the Ryukyu Volcanic Arc of the broader Western Pacific Volcanic Regions. Situated at 25.63° N, 122.08° E in the Northern Hemisphere, the volcano lies within a subtropical climate zone. At just 120 meters above sea level, Pengchiahsu is a relatively low-elevation volcanic feature. Despite its modest height, it remains an active geological formation with the same underlying magmatic processes as its taller counterparts. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Pengchiahsu is one of five small Pleistocene volcanic islands NE of Taiwan. The summit of the andesitic island (also known as Agincourt) reaches only 129 m above sea level. The age of volcanism is considered to be Pleistocene, but it was reported to display fumarolic activity (Volcanological Society of Japan, 1971). However, there are no more recent reports of fumaroles or other indications of ongoing unrest as of 2015, and the Central Geological Survey makes no mention of them, though it does for other locations.

How high is Pengchiahsu?+
Pengchiahsu has a summit elevation of 120 meters (394 feet) above sea level. At 120 meters, it is a relatively low-elevation volcano.
What type of volcano is Pengchiahsu?+
