Al Idrisi is a submarine mud volcano in the Atlantic Ocean west of Morocco . At a height of 255 meters above sea level and a diameter of 5.4 kilometers, it is the largest mud volcano in the El Arraiche mud volcano field near the Moroccan continental shelf in the Gulf of Cádiz . The area with its carbonate hills and mud volcanoes was discovered in May 2002 by the Belgian research vessel RV Belgica .
The highest point of Al Idrisi is a little less than 200 meters below sea level. The volcanic cone is surrounded by a deep, horseshoe-shaped trench towards the open sea. The flanks are thickly covered with recently swollen mud that flows into the ditch in thick, bulbous streams. The crater has a well-shaped outer ring and an inner dome . The eruptions occur in phases and seem to occur more or less synchronously with the mud volcanoes in the area.
The mud volcano is named after the cartographer , geographer and botanist al-Idrisi , who was born in North Africa and lived in the 12th century.
