The Most Dangerous Volcanoes in the United States

Показать описание

Which volcano in the United States is the most potentially dangerous? Surprisingly, it is NOT Mount St. Helens. This video will discuss which 5 volcanoes out of the 160 in the country are the most potentially dangerous and why this is the case.

My first guess would be Mount Rainer, due to its proximity to heavily populated areas and the fact that it is highly prone to devastating lahars.

I've really come to appreciate this channel in helping me deal with volcano anxiety. I live close to one of these "Most Dangerous" volcanoes, but learning about them from your videos makes me feel very informed about the risks, likelihood of eruption, and potential consequences of an eruption. If there is a disaster planning youtube channel, I think a collaboration between you and them on how to prepare for an eruption would be very informative! Something to look into!

Very interesting. I was sure Rainier was going to be #1 simply because it will affect highly populated areas, but I was not considering the eruptive history of the various volcanoes and the fact that the type of eruptions they produce does change over time. I did recently learn that Kilauea sometimes produces explosive eruptions, I was still surprised that it was #1. Thank you for a very informative video.

Glad mt shasta made it in here. I want to know more about the landslide that happened there, given in ur past videos you said there was hunkered terrain or debris from a landslide

Thanks as always, Geology Hub! Thanks for the clarification about Kilauea's 1790 eruption and how many people it killed.
This is a very insightful list, containing very fascinating volcanoes.

Thanks, GH, straight to the point with the volcanoes as always.

If it weren't for the Osceola mudlfow, we (possibly) would have had the tallest mountain in the lower 48! And a much more visually worthy candidate for that title, in my entirely biased opinion.

Again, it must be noted that the Western Continental USA (excluding Hawaii and Alaska of course), has scores of active (yet dormant) volcanoes, yet they almost never erupt.
I'm 52, but Mount saint Helens is still the only one to do so.

Thanks for all the hard work on these videos

Thank you, GH. Interesting as always!

TBH, I wasn't surprised that Kilauea was considered the most dangerous volcano. As well as the stated factors, The fact is that, despite its frequent eruptions, people are building houses on old lava flows in active rift zones... and getting very surprised when those rift zones spring to volcanic life, like LERZ in 2018. There is also the deadly assumption that because its effusive, it's not that dangerous...a case of familiarity breeding potentially lethal contempt!

GH, you are my favorite teacher! Thank you, have a great week! ❤

I wouldn't have put kileuea #1, but your reasoning makes sense, the rest are not surprising

Most people don’t know that Mount Saint Helens ash fall actually saved probably 40 or 50 carpenters, labored and ironworkers when one of the ash falls closed down construction on the Satsop Nuclear Power Station. The ash landed on the site and the crews were sent home until they could get the work areas cleaned up. That particular day, the contractor I was working for, Chicago Bridge and Iron Inc., had their giant self erecting tower crane collapse and fall into an area where those workers had been working. They would have either been seriously injured or killed by the crane parts and debris that impacted the area. I was working on the other side of the containment vessel and was shaken up by the accident! Amazingly, nobody was killed. I think 3 guys were injured, none seriously. The crane was the tallest equipment working on the site at the time of the accident.
