Al Wahbah, on Harrat Kishb, is the most spectacular of several volcanic explosion craters found on the lava fields of western Saudi Arabia. A Quaternary phreatic event drilled out a crater 2 km in diameter through Proterozoic basement rocks and Quaternary lava flows. The crater is rimmed with a tuff ring of debris from the explosion, around which were diverted Holocene basaltic lavas.
