Tuya Volcanic Field Concepts

The video discusses the lesser-known volcanoes in British Columbia, focusing on the Tuya Volcanic Field. It explains the formation of tuyas, a type of subglacial volcano, and details the history and features of the volcanic field, including its various vents and recent activity. The potential for future eruptions and their likely impact is also covered, with the Tuya Volcanic Field classified as a very low threat.

Which volcanic feature in British Columbia erupted a lava flow that crossed into Alaska in 1904?

• Iskut Unuk River cones
