The Ashintully Volcanic Belt is a term in Meckelnish geology for large volcanically active region that comprises the Genevelond Peninsula, Treynor Archipelago and Glanurchy Island, presently the country of Meckelnburgh.

Etymology

The term "Ashintully" has existed since the 1450s AN to refer to the series of volcanos lying at the western edge of the Teir'Dal Corridor. It meant "Mighty Volcano" in the ancient Dagoran language, a name given under the ownership of the region by Menelmacar.

Geology

The Ashintully Volcanic Belt remains a volcanically active region, and is responsible for a significant portion of the geography in Meckelnburgh and Hergilsey. The majority of the volcanology rests in the Comstokia Zone, along the Comstokia fault. This is a leaky transform fault that has produced a line of volcanoes parallel to the Genevelond Peninsula, moving eastward. Two mantle plumes under the Siyon Thermal Field in northwest Meckelnburgh and Mt. James in Hergilsey are responsible for their anomalous volcanic activity.

Activity

The eastern half of the Comstokia Zone retains its potential for activity, and may presently feed Mt. Tomsohnd and others in eastern Meckelnburgh. Mt. James is an actively erupting volcano on Glanurchy Island, and continues to produce a lava lake and fissure vents, especially down its western slope. Likewise, the Siyon Thermal Field is active and filled with dozens of active geysers and hot springs. The Siyon Hot Spot nonetheless continues to fill, raising the depression responsible for Lake Siyon each year.
