He also reached out to Dick Ostrander, director of what is now Yakima Valley Libraries, to see if he could find out if any other modern city had dealt with the ashfall of a volcanic eruption before. Ostrander checked with his connections with the Library of Congress and other institutions and gave his report to Zais at the end of the day.

“He said, ‘I have good news, and I have bad news,’” Zais recalled. “‘The bad news is there is no other example in the modern world where an urban area was infiltrated by ashfall.’

“I said ‘That’s not great. I don’t want to be reminded about Pompeii,” the Italian city that was entombed for centuries by ash from Mount Vesuvius in the year 79.

“‘The good news,’ Ostrander said, ‘Is when you figure it out, you’ll be the standard of care. So you better get it right.’”

That was before I moved to the northwest. Must have been horrific. Can't say I'm sorry I missed it.

I rode a mtn bike across the Plains of Abraham on the flanks of the mountain. It's really strange. The initial estimates were that it would take 50-75 years for the area to recover, but most everyone was amazed that it happened MUCH quicker. It's still obvious that something happened there but in about 10 years it went from a barren moonscape to what looked like a clear-cut forrest.

I was on an Amtrak train from Seattle to Chicago the day of the erruption that went through the ash cloud. One of the strangest things I've ever experienced. Flocks of birds were flying in circles....

Now picture 70,000 years ago... what is now Lake Toba in Indonesia. Then, it was a range of hills 19 miles wide, by 60 miles long.
It was the "Mount" Toba supervolcano. It blew 2,800 TIMES the debris into the atmosphere that Mt. St. Helens did. It took a range of high hills, and turned it into Lake Toba, 19 miles wide, and 60 miles long.
It blotted out the sun, worldwide, for months. Humans dwindled from a few tens of millions, down to under a few tens of thousands. It was the largest eruption on earth in the last 25 million years.
It created a genetic bottleneck that we can trace even today... Most of the genetic groups of humans outside of East Africa became extinct, or diminished so severely that in the next 10,000 years or so, their genetic line fizzled out.

I remember Mt. St. Helens. I remember here in Northern California getting 1/8" or so of ash on things.
I was impressed.

But, compared to Toba, it was a barely noticeable fart.

Not unlike some of today's COVID misanthropes, an old throwback, oddly enough named Harry S Truman, refused to believe he was in danger and stayed behind that day.

Harry was never seen again.

He was the only direct fatality, and it was his choice I suppose. We had plenty of advanced notice. They started moving people out weeks before.

A former GF's father was a geologist for the USGS in 1973 and they did a survey of the Cascade range to asses the risk of vulcanism. The team's report said essentially no risk. He strongly disagreed and filed a dissenting report, warning of St Helens blowing within a decade. 7 years later, kerbloeey.

Nope. There were 57 people killed by the eruption and at least three were killed directly by the blast, Harry R. Truman, Dave Johnston (a USGS geologist), and Reid Blackburn (a National Geographic photojournalist).



"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

Pyroclastic flows are deadly.
