The elongate Ketildyngja shield volcano, the most prominent feature of the Fremrinámur volcanic system, formed about 4,000 years ago and contains a distinct summit crater of about 400 x 800 m. Associated fissure systems extend from just northwest of Askja, across the Ketildyngja shield, and about 130 km to the northern coast of Iceland.
