Taranaki volcanTaranaki (Egmont) volcano is an isolated steep andesitic stratovolcano located in the SW part of the North Island of New Zealand. It is the second highest peak on the North Island and one of the most active volcanoes in New Zealand and has last erupted in 1854.
Introduction:Taranaki is surrounded by a ring plain of debris-avalanche and lahar deposits that and extend to the coast. The isolated Taranaki 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.

1655 AD Burrel Lapilli eruption
The largest known eruption of Taranaki in recent centuries was a major explosive (subplinian VEI 4) eruption around 1655. Following the extrusion of a small lava dome, the eruption culminated in an explosive phase that produced the so-called Burrell Lapilli covering over 200 square km of the North Island in pumice. The eruption is an example for the transition from effusive (lava dome formation) to explosive eruption style:
