Yeah I have heard a podcast about her recently, and apparently the book Year Without Summer talks about how the 1816 eruption of Mount Tambora was so violent that it covered the entire world in ash and caused a mini ice age event. Insane to imagine, but paintings from this time will show the sky with strange colors.

Supposedly the force of this eruption was estimated to be 100x the force of Mount St Helens, which was enough to completely deface a mountain.
