The Volcano (British Columbia) The Volcano being one of the three having erupted in the last few hundred years. Tseax Cone, which last erupted in the 18th century, is the southernmost volcano in the province, while Prindle Volcano in easternmost-central Alaska, which erupted more than 10,000 years ago, is generally considered the northernmost. At least two phases of volcanic activity have been identified at The Volcano. Each event was followed by the eruption of lengthy basaltic lava flows that flowed down steep granitic flanks of the mountain ridge on which The Volcano lies. After this took place, they travelled through the Lava Fork valley
Zuidwal volcano mineral composition, points to volcanic activity as a result of subduction far away from the volcano. During the Cimmerian Orogeny, the Cimmerian Plate collided with Kazakhstania, sending shock waves through the Eurasian Plate, resulting in volcanism. The volcano is covered by layers of sandstone from the early Cretaceous that act as reservoir rock for the gas. The seal rock consists of shale. The volcanic rock is magnetic, creating a magnetic anomaly. Zuidwal volcano The Zuidwal volcano is an extinct volcano in the Netherlands at more than below ground under the Wadden Sea, between Harlingen and Vlieland, just south west of
