There are no Holocene eruptions known for Tuya Volcanic Field. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

A broad region dotted with formerly subglacial volcanic cones known as tuyas forms the Tuya volcanic field near Tuya Lake and a broad area to the north. Although tuyas, the products of Pleistocene subglacial eruptions, are perhaps more well-known in Iceland, these predominantly flat-topped basaltic table mountains derive their name from the Tuya region in the Cassiar Mountains and Tanzilla Plateau area of northern British Columbia. Tuya Butte itself, immediately north of Tuya Lake, has no summit crater or obvious vent, suggesting fissure-fed eruptions, although several indications suggest a vent location near a large cirque on the north face. Other tuyas lie in the High Tuya Lake, Iverson Creek, Rancheria River, and Klinkit Lake areas. Several small subaerial shield volcanoes, and postglacial lapilli cones and lava flows have been reported in this area. At least one of these, Grabrielse Cone near the headwaters of Iverson Creek, is of Holocene age.
