Other examples of somma volcanoes can be found on Russia's Kamchatka Peninsula and the Kuril Islands, stretching south from Kamchatka to Hokkaidō, Japan.

The Somma volcano is located in the Campania region of southern Italy, near the city of Naples, and is believed to have formed over 25,000 years ago. The volcano has a collapsed caldera of an older volcano, with Mount Vesuvius rising up from the center. Both the Somma volcano and Mount Vesuvius are part of the Campanian volcanic arc, which is known for its high levels of seismic and volcanic activity. Despite the potential dangers associated with living near an active volcano, the Somma volcano and its surroundings are a popular tourist destination, attracting visitors from around the world who come to see its unique geology and learn about the region's fascinating history.
