Djibouti, trending NW from the
 
  Red Sea, contains a broad area of
 
  youthful fissure vents between
 
  Lake Asal and the Ghoubbat al
 
  Kharab gulf. The rift is subaerially
 
  exposed over a 12 km distance
 
  between these two bodies of water
 
  and contains numerous basaltic
 
  cinder and spatter cones. Magma-
 
  water interaction has produced tuff cones, some of which form islands or are
 
  breached by the sea. The most recent lava flows are younger than lake
 
  sediments deposited 5300 years ago. These lavas were thought to have been
 
  erupted during the past 3000 years (Delibrias et al., 1975). The Ardoukôba
 
  fissure erupted in 1978, producing a small cinder cone and lava flows that
 
  covered part of the rift floor near the Red Sea. (Global Volcanism Program))
