The Northern Cordilleran Volcanic Province has been a zone of active volcanism since it began to form 20 million years ago. Unlike other parts of the Pacific Ring of Fire, the Northern Cordilleran Volcanic Province has its origins in continental rifting—an area where the Earth's crust and lithosphere is being pulled apart.

Lava fountains can occur in the Northern Cordilleran Volcanic Province roughly every 100 years. [10] Level Mountain, the largest volcano of the Northern Cordilleran Volcanic Province. The large brown area in the middle is a dissected stratovolcano and the surrounding light brown is the broad shield volcano comprising a lava plateau.
The well-established local name for the volcano, Tseax Cone, became official on December 13, 1991, and was adopted on the National Topographic System map 103P/2. [ 2 ] [ 8 ] To the Nisga'a , Tseax Cone is known as Wil Ksi Ba x hl Mihl ; in their language it means ' Where the Fire Ran Out ' , which is a reference to the volcanic eruption that ...
There are around 200 volcanoes in Texas that have been extinct for millions of years, making them unlikely to erupt again, because the volcano no longer has a magma supply. It could however be ...
Over half of the Northern Cordilleran volcanoes are located in northwestern British Columbia. This portion is where the most recent eruptions in Canada and of the Northern Cordilleran Volcanic Province have occurred, including the catastrophic 18th century eruption of Tseax Cone and the 1904 eruption of The Volcano.

The eruption rate of the MEVC has varied throughout its long volcanic history. When the volcanic complex started erupting at least 7.4 million years ago, it increased the rate of magmatism in the Northern Cordilleran Volcanic Province from 100,000 to 300,000 cubic metres (3,500,000 to 10,600,000 cubic feet) per year.
