What is volcanic ash made of?

Volcanic ash falls happen infrequently in Alaska. But when there’s enough of the stuff, volcanic ash can pose a risk to people, automobiles and airplanes. Kristi Wallace, a geologist with the USGS, studies ash to better understand volcano behavior and risk.
The Alaska Volcano Observatory is a partnership between the USGS, the Geophysical Institute of the University of Alaska Fairbanks, and the State of Alaska Division of Geological and Geophysical Surveys. Scientist from around Alaska work to understand volcano behavior and keep the public informed during eruptive events.

I know Kristi! I met her during ANSEP!

[@TheBereangirl]

I was in Spokane Wa. when Mt. Saint Helens blew her top. Thought is was snowing in May! It was gray for months and we had to wear masks for a long time. I was around 8 or 9...not fun as a kid.

how to test some powder is the real vulcanic ash or not?

[@Maricarmjolo]

Very informative

[@luciusirving5926]

Volcanic ash and fly ash F have the exact same properties. Both make green concrete.

Can we smelt volcanic ash?

[@Blue_Neptune21]

Obviously the smelting process is not understood by the viewers … you want to make some lava?

So in other words, volcanic Ash is just spicy sand?

[@luciusirving5926]

It's also green cement.

[@drdouble2518]

Can you identify rocks made from ash specifically? Lets say a twenty ton pile shovelled there half a million years ago....

Here to understand ash after the La Soufriere volcano in St. Volcano has erupted.

Fine, but it didn't really answer the "made of" question. Which one looks for to understand carbon dating fossils videos.
