Auckland, New Zealand's largest city, is constructed over the 140 km2 Auckland Volcanic Field. The field contains more than 50 maars, tuff rings, and scoria cones that were formed during eruptions over the past 150,000 years. Of the 19 eruptions known to have occurred during the past 20,000 years, only one took place during the Holocene. Activity about 600 years ago formed a low shield volcano at Rangitoto capped by a scoria cone. Photo by Jim Cole (University of Canterbury).
