Dilo-Dukana volcanic field

Description

The Dilo-Dukana volcanic field is a Pleistocene volcanic field extending across the Ethiopia–Kenya border of East Africa. It has a northeast trend and contains 52 eruptive centres, 26 of which are still well-preserved. Most of the eruptive centres are in the form of cinder cones, but the well-preserved centres consist mainly of maars. Eruptions in the Dilo-Dukana volcanic field occurred from several fissures as suggested by the orientation of the eruptive centres; they occur in clusters or alignments. Argon–argon dating of four samples obtained from the Dilo-Dukana volcanic field in 2019 yielded ages ranging from 0.3 to 0.13 million years old. The largest lava flows in the volcanic field engulfed areas of nearly 17 km2 (6.6 mi2).
