Symmetrical Taranaki (Egmont) volcano dominates the western coast of New Zealand's North Island. The 2518-m stratovolcano, seen here from the south, is surrounded by a ring plain of debris avalanche and lahar deposits produced by repetitive collapse of the volcanic edifice. Taranaki (Egmont) has been active throughout the Holocene. The latest eruption of Taranaki took place in 1854 CE.

Tarankai (Egmont) volcano has a breached summit crater that is occupied by a partially destroyed lava plug. This view from the SE shows the stacked lava flows that form much of the cone, with the vegetated slopes of the parasitic volcano, Fanthams Peak, at the left. Both Taranaki, the Maori name, and Egmont, the name assigned by Captain Cook, are used for the volcano.

Grass-covered conical hills dot the plains around Mount Taranaki (Egmont), on New Zealand's North Island. Small hills such as these, often located in lowland areas well beyond the flanks of a volcano, were once thought to be cinder cones or small secondary vents produced by explosions when a lava flow passed over a body of water. They now are known to be hummocks of massive debris avalanches produced by volcanic landslides. Debris-avalanche deposits originating from repetitive collapse surround the volcano to distances of about 40 km.

The pasture-covered, hilly terrain in the foreground is part of a vast ring plain of debris-avalanche and lahar deposits that surrounds Mount Taranaki (Egmont). Repetitive collapse of the volcano during the late Pleistocene and Holocene produced debris avalanches that reached the western coast, nearly 40 km from the volcano.

An aerial view from the south shows Mount Taranaki (Egmont), with its parasitic volcano of Fanthams Peak at the lower right. The summit of Taranaki contains a partially destroyed lava dome; four other lava domes are located low on the south and north flanks. Taranaki volcano collapsed and rebuilt itself repetitively during the late Pleistocene and Holocene.

Taranaki volcano, seen here from the SW, rises to 2518 m above the Taranaki ring plain, with its parasitic volcano Fanthams Peak on the left. Taranaki (Egmont) is the youngest and SE-most of a group of volcanoes beginning with the Kaitoke Range, near the west coast of North Island. Tarananki has been active during the past 125,000 years. Its most recent activity, during the 15th to 19th centuries, included the eruption of airfall tephra, pyroclastic flows that traveled to the NW, and emplacement of the summit lava dome.

Mount Taranaki volcano is the centerpiece of Egmont National Park on the western side of the North Island of New Zealand. Farmlands surrounding the volcano extend to the boundaries of the national park, leaving a circular pattern prominent from space. The Pleistocene Kaitoke Range forms the topographic high WNW of Taranaki.
