The nearly symmetrical, steep-sided cone of Taranaki (also known as Egmont), is New Zealand's largest andesitic stratovolcano. Taranaki is surrounded by a ring plain of debris-avalanche and lahar deposits that and extend to the coast. The isolated volcanic center is located on the west coast of central North Island at the southern end of a volcanic arc extending NW along the Northland Peninsula. Taranaki is the youngest and SE-most of a group of three volcanoes beginning with the Pleistocene Kaitoke Range. Fanthams Peak breaks the symmetry of Taranaki on its south flank, and four lava domes are located on the lower north and south flanks. Multiple episodes of edifice collapse have occurred in the past 50,000 years. Explosive activity, sometimes accompanied by pyroclastic flows and lava dome growth, has occurred frequently throughout the Holocene. Taranaki's latest eruption took place in 1854 CE.
