The northern basalt lava field of the Alid volcano (No. 3) is limited at its northern margin by the products of the silicic volcano of Jalua. This is a strato-volcano with a large central volcanotectonic depression open to the sea. The silicic rocks of the volcano are apparently peralkaline. There is fumarolic activity on the western flanks.
