The Marrah Mountains or Marra Mountains or Fugo Marra (In fur language) or (Jebel Marra, Arabic: جبل مرة bad mountains) is a range of volcanic peaks created by a massif that rises up to 3,000 m. It is located in the center of the Darfur region of Sudan, specifically within Dar Fur and neighboring areas. The highest point is Deriba Caldera. The upper reaches of the massif is a small area of temperate climate with high rainfall and permanent springs of water.
The last eruption occurred around 1500 BC. The centre of activity was Deriba Caldera, and involved caldera collapse following the eruption of pumice and pyroclastic flows which travelled over 30 kilometres (19 mi) from the volcano.
