Krakatoa I think
powder to sand size my butt (thought there is plenty of that)...we had gulf ball size pumice falling on the ships after Pinatubo went.
Krakatoa 1883 or Tambora 1815?
Both had significant world wide climate effects.
The Summer without a Sun here in TX.
Here is a nice article to peruse in your leisure.

We didn’t have any paint problems with Mt. St. Helen’s volcanic ash.
Did you go for a swim? Venomous sea snakes in the lake!
Well, I can’t resist...... things I should probably not have done.
Back in 1966, I lived in Manila and took the opportunity to get a student pilots license and take flying lessons. I flew solo in an old ,very old piper cub J-3. You could literally see daylight through the seams in the floor. but I digress. It was cheap. Very very cheap.
I flew on Saturday mornings. The flight was from Manila International out to Taal Volcano and back plus enough time as required to get an hour in. I regularly flew above and through the dissipating steam drifting up from the volcano.
On reflection that was about as dumb as the time my friend and I beat on a hollow tree to get the bear cubs to poke their heads out so we could get a photo
Thanks - both were bad, but Krakatoa is the one I was thinking of. I found an old book at the thrift store about it - large format with lots of drawings and old photos.
Mixed in were native accounts, some nearby ship’s logs, newspaper articles, tide logs from around the world, etc. A real interesting and detailed mix of information.
The eruption caused a huge tsunami. Tide records in England even recorded the event. I don’t recall now if it was the tsunami or the “ringing” of the planet due to the shock wave that caused the change in water depth in England.
Found the following abstract for a paper on the net. Not sure I understand it from this, but it sounds like it was from the air wave affecting the water. That is one heck of a boom to have the air shock wave travel around the world!
“Tide gauge disturbances detected at many places around the world after the explosive eruption of Krakatoa in 1883 cannot be explained as free ocean waves traveling by the shortest sea route from Krakatoa, but were clearly correlated with the air wave. Previous explanations of the way in which the air wave caused the tide gauge disturbances are shown to be unsatisfactory from the point of view of both theory and observation. It is suggested that these disturbances were in fact free waves generated by the air wave at major changes in depth in the ocean, notably the continental slope. This mechanism is investigated for both normal and oblique incidence of the air wave on a step. The tide gauge disturbances observed after the eruption of Krakatoa are shown to be consistent in arrival time, time scale and amplitude with the predictions of the theory.”
Pinatubo is actually between Subic Bay and Clark. That is you must fly over the mountains to get from Subic to Clark.
Thank you. IIRC, a close look at the data shows that CO2 concentrations lag the temperature changes. That is, the CO2 levels are caused in part by temperature changes, and not the other way around.
I carry dust masks in my vehicles ever since St Helen’s blew.
Actually, that was the ash I was talking about. I was in Grand Forks, ND, and people were complaining about the ashfall ruining their paint jobs, scratching up the cars pretty heavily.
Hope you are coping okay.
I wonder if the damage wasn’t caused in a car wash.
Probably a Dodge Caravan.
This event may be shaping up to match that in 1754
https://en.wikipedia.org/wiki/Taal_Volcano#The_1754_eruption
Thats based on ocean temps.
Volcanoes are not in that category.
If we have something like the 1754 eruption, it could approach Pinatubo in amount of ash erupted into the atmosphere. That will have a huge effect on summer temperatures as the ash cuts down on sunlight reach the surface of the Earth quite a bit.
Just looked it up and there was more engine damage than paint. The ash actually turned to glass in the engines.
I did look up Dodge Caravan and they seemed to have a lot more than just paint problems.
