The city of Honolulu drapes the lower flanks of the massive Koolau shield volcano on the island of Oahu. Most of Koolau volcano is of Pliocene-to-Pleistocene age, but a series of late-Pleistocene to perhaps early Holocene explosive eruptions formed a chain of tuff cones, cinder cones, and spatter cones at the SE end of the island. The largest of these is the Diamond Head tuff cone (lower right), which forms a dramatic backdrop to the city of Honolulu.
