Well, I really messed up that Mystery Volcano Photo, eh? I had, in fact, posted that very image before of Kirishima to show the "before" of the crater [head slap - see top left for "after" image]. Yes, Eruptions reader Mike L. submitted the image, taken in 1990. We'll give Don Crain credit for getting the location/date of my slip up right - and half a point to Eva for getting the location as well.
So, the current standings
To make up for my mistake, I'll leave you with a new MVP that should be more of a challenge. For this, you need the location in the image, when it formed and why this is a mystery volcano photo - as specific as possible. Good luck (and I know I have posted this one before!)
