In various places he has different names (Namu-fyal, Dal-fyal, Leire nukura). It reaches a height of 400 - 600 m and a width of 400 km. Cracks, limiting its accompanied by a continuous series of craters, vylivshih huge masses of lava. Period of strong eruptions of their time was between 1724 m and 1730-mi for years. Now, these cracks are fumaroles, solfatary and keys, spewing hot mud. Among the volcanoes mosquito lake especially curious Ver fyal, featuring his very proper form. Sharp contrast to this grand volcanic eruptions represent the tiny cracks that resemble some kind of artificial model and observed Toroddsenom in southern Sveynagi. At one of these cracks, which has a length only Hume and width 10 - 12 cm, are 12 tiny craters, of which the largest reaches one meter in diameter, while the rest is not more than 12 - 16 cm The same crack with a tiny volcanic lava flow Toroddsen found in Helgafela peninsula Reykjavik, Nese. In the mosquito lake in northern Odada-Rauna move the earth's crust - faults and shifts - have occurred in the north-south direction. On the contrary, in the southern Odada-Rauna cracks directed mainly to the northeast. Among the latter, and includes rows of craters Kverknuka Ranney and Ding Halls. Kverknuka Ranney consists of many cone-shaped cliffs of tuff and breccia between them in the most fantastic forms piled lava. Profiles of area between Kverknuka Ranney and Dingyuholsom shown in Fig. 182 and 183, provide a visual representation of the structure of this beautiful volcanic area.
