Edziza is now (due to recent published papers) considered to be the most active Canadian volcano, with one eruption occurring about every 250 years on average. (For those wondering what is the second most active in Canada, it is the iskut unuk river cones)

GeologyHub, your explanations are clear and to the point. It’s amazing how you can give a five minute presentation that most take 45 minutes to an hour to do so. I consider your channel the ultimate Cliff Notes on volcanos and other geologic oddities. Your efforts are invaluable to busy people with busy lives.

This is EXcellent. Thank you for posting it

Love this .

I will not see the time when man can influence a volcano.

You can't carbon 14 date rock. There are many ways you can date rock which is volcanic in origin, but carbon 14 dating is not among them. Carbon 14 dating works on once living organisms which are under 50,000 years old. Bad information right at the beginning of a video is never a good sign.

Stratovolcanoes don't erupt for more than 3 million years at the most. Subduction and plate techtonic movement, which creates Stratovolcanoes, doesn't work like that. Mantle plumes, however, will work like that. In 8 million years, the North american plate has traveled west southwest about 750 miles. Example: the Yellowstone hotspot was in south Oregon 8 million years ago. None of the current stratovolcanoes on the west coast had appeared yet. Do some research, okay?

Its oldest known eruption site is actually about 15.7 million years old. I do forget if that is in Oregon or California. Or if it was in California but got moved to Oregon because of the clockwise rotation of the Juan de Fuco plate. Things that complicate everything is all the terranes the North American continent has run into and their multi-directional travels. An island that is mostly in British Columbia is where they have found Washington’s first, and only, dinosaur bone. Part of a T-rex thigh. Thing is, it died in Mexico.

time stamp@4:37 carbon 14 dating of rocks? really, how do they carbon date rocks? I thought you need biological stuff to carbon date anything older then 50,000 years (1/2 life of co14) darn near every rock unless Mother Earth just spit it out is older then that correct or not??? !!! google = Why can you not carbon date stone? For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue. other wise enjoyable. .

I completely didn’t notice that until I read your comment. I only have my associates degree in biology so I ask a lot of dumb questions but: is it possible for the carbon 14 dating dating to be performed on rocks if there are fossils inside? Like even fossilized plant life? If evidence of plants and creatures are trapped inside the rocks, can they carbon date them in that way??? Just a thought/question because your comment got me THINKING now lol

@@seasickshark thinking is a good thing I do it all the time. I wondered as you did and couldn't recall hearing of rocks being c-14 dated so I went to google and found a lot about this subject and rocks no, organic yes. Up to 50,000 years in age accurately (half life c-14) and falls off big time after that.

@@seasickshark Short answer, no. Long answer, maybe, but not if something is properly fossilized, there's no carbon left...it's been replaced by minerals. And not in the case of something like coal, it's been down there so long it doesn't have any carbon 14 left to measure. Something biological preserved in an anaerobic environment?...quite possibly, and that is frequently done in geology, archaeology and paleontology. They can also use other radiometric dating techniques to measure the rock the fossils are found in to get a date for the deposition of the fossil layer.

It is very common for volcanoes to form glaciers. Glaciers do not form from snowfall. Mount Saint Helens developed a massive glacier in less than six months after its eruption. There was more ice in Helens than ten years of snowfall could produce in less than one year. Volcanoes cause glaciers. I guess that's easy to not notice in cold Canada, but volcanoes in Hawaii have glaciers, too.

According to all the literature I’ve read on glaciers, they are formed as snow accumulates over time and turns to ice. There are thousands of sources online that state this.

@@Micah98134 That's like claiming that all the water in Crater Lake, Oregon comes from rain or snow. There is not enough precipitation to justify that. There is very little catchment. Just like many mountain-top lakes and ponds found throughout every mountain range there is no way to justify more water coming out than water falling down without acknowledging subterranean sources. "All glacier material comes from snow" is a very simple thought. That makes it attractive to simple-minded persons irrespective of the fact it does not match the evidence.

This is idiotic. Then why are there glaciers on non-volcanic mountains? Or are we on Enceladus? Water and sub-zero °C temperature causes glaciers. Full stop. Typically it's from precipitation. So, you can have air, that is moist but still below the saturation/precipitation point of the air at that combination of pressure, altitude and air temperature, flowing at higher altitudes that allows accumulation of ice without obvious precipitation. This can be compounded by day/night warming cycles. Volcanos can emit large amounts of water vapour that then condenses at the higher altitudes, but this is only a function of altitude and latitude, not an innate function of being a volcano.

@@clusterfer When vapor is released from pressure temperatures fall dramatically. That is how air conditioners and refrigerators work. When a hot spot is deep in the mountain water and CO2 rise at ambient temperatures, release from pressure near the surface, the CO2 evaporates, freezing the water. The stream or spring emerges as frozen water. Look for glacier heads which have little to no catchment area. They come from hot spots. Mount Shasta's glaciers, for instance, grow or recede unevenly because they aren't from snow or rain and the vents vary in output. Mount Kilimanjaro has glaciers but the air never gets near freezing. Name one non-volcanic mountain and I'll show you otherwise. Examine Ute Mountain and the surrounding volcanic mountains. Find El Garita caldera. Those mountains are all volcanic, too. All mountains look alike because they're all volcanic.
