Ash: A Jagged Little Potential Electricty Conductor
Ash particle, 1980 Mount St. Helens eruption, magnified 200 times
Last night I found some fascinating and informative details about volcanic ash on this USGS site:
Volcanic Ash, What it can do and how to minimize damage
For instance, did you know that volcanic ash...
- does not dissolve in water
- is not soft like sand, but very abrasive and corrosive
- conducts electricity when wet
- is formed by the force of escaping gas when it violently shatters solid rock
Exciting, huh? Being a geology hobbyist and living in the Ring of Fire definitely has its perks.
