Harrat refers to a volcanic field, primarily found in the Arabian Peninsula, particularly in Saudi Arabia. These fields are characterized by numerous volcanic cones and lava flows, resulting from past volcanic activity. The most notable of these is the Harrat Rahat, which is located near the city of Medina. The volcanic activity in Harrat has shaped the landscape and influenced local ecosystems. The area is often studied for its geological significance and is home to various species of flora and fauna adapted to the unique environment created by the volcanic terrain.
