Global Volcanism Program | Image GVP-10424
Harrat Khaybar, one of Saudi Arabia's largest volcanic fields, covers an area of more than 14,000 km2 to the N of Madinah (Medina). This Space Shuttle image shows the central vent area of the volcanic field. Light-colored areas at the center of the image show lava domes and tuff rings; above this area is Jabal Qidr volcano. The lava flows extending to the W from the central vent area are young prehistoric and historic. An eruption was reported in early Mohammedan times during the 7th century CE.
