caption_attribution_description: English: The darker-colored area extending diagonally to the right down the center of this Space Shuttle image is Harrat ar Rahah, the northernmost of a series of Quaternary volcanic fields paralleling the Red Sea coast of Saudi Arabia. The geometrical outlines of the historical town of Tabuk (top-center), located on the road leading from Hijr to Damascus, can be seen to the north. There are fewer young volcanoes in Harrat ar Rahah than in other harrats (lava fields) to the south.
context_page_description: Al Harrah is a large basaltic volcanic field in northwestern Saudi Arabia near the Jordanian border. It covers an area of 15,200 km². The volcanic field forms the southern third of the massive Harrat al-Shamah volcanic field, which extends from Syria through Jordan into northern Saudi Arabia. It is in the Tabuk Region of northwest Saudi Arabia. It is one of a series of Quaternary volcanic fields paralleling the Red Sea coast.
  The Saudi Arabian portion of the Harrat Ash Shamah volcanic field extends across a 210 km-long, roughly 75 km-wide NW-SE-trending area on the NE flanks of the Sirhan Valley and reaches its 1,100 metres high point at Jabal Al-Amud.
  Activity began during the Miocene; a younger eruptive stage, at the SE end of the volcanic field, occurred during the late-Pleistocene and Holocene. It is known to have erupted in historic times. Vegetation is characteristically open acacia shrubland with patches of juniper at higher altitudes
