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 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.

The eruption rate of this period was much greater than what is observed for the Northern Cordilleran Volcanic Province today. [1] Following the onset of activity at Edziza, Maitland volcanism commenced 5.2 million years ago with the outpouring of alkali basalt and hawaiite lava on a broad, late Tertiary, low-relief surface. This resulted in the ...
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.

Tseax Cone is one of the southernmost volcanoes in the Northern Cordilleran Volcanic Province. [10] This is a broad area of shield volcanoes, lava domes, cinder cones and stratovolcanoes extending from northwestern British Columbia northwards through Yukon into easternmost Alaska. [27]
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.
A volcano belched a plume of ash and steam into the night sky in the central Philippines in a powerful explosion that sent more than 700 people fleeing to evacuation camps. The explosion of Mount ...
PHIVOLCS Observatory at Mount Hibok-Hibok.. The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Filipino:; Filipino: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya [2]) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the ...
