Details for: Tofua
A small plume rises from Lofia cone on the N side of the caldera lake of Tofua volcano in this 1990 aerial photograph. Recent tephra was emplaced onto the caldera rim to the NW. The steep walls of the 5-km-wide caldera are about 500 m high. Three post-caldera cones were constructed at the N end of a cold fresh-water caldera lake, whose surface lies only 30 m above sea level. Aerial photo by Tonga Ministry of Lands, Survey, and Natural Resources, 1990 (published in Taylor and Ewart, 1997).
