Ya it’ll take a while to determine..
One big thing is..did it umbrella at extreme height? How high did it spew? Etc. I have seen 55 thousand feet, but thats all the speculators around.
I will wait for the real actual reports. The USGS is one of the few government agencies that is still fairly good at this stuff. They work with all the global volcano geologists, etc.
The source in the video indicated 98,000 feet.
