individual lava fields cover over 20 square kilometres (7.7 sq mi) of surface, but surfaces of about 10 square kilometres (3.9 sq mi) are more typical. There are usually only a few flows per vent, although they often have lobate structures. The surface of the lava flows has varying textures and often contains hills or ridges, generally corresponding to

Bayuda is an elongated volcanic field with fresh volcanic features extending over an area of 11 by 48 kilometres (6.8 mi × 29.8 mi) in a northwesterly direction. Within this area, a number of volcanic vents within a narrow space have formed a continuous volcanic surface. Some
