1992 Spurr Eruption Case Discussion
27 Apr 2011 | Contributor(s):: William I Rose
This lecture summarizes distal ash cloud observations via satellite and radar, along with information about meteorology and fallout, for the 1992 Crater Peak/Spurr eruptions. These small subplinian events produced significant fine and very fine ash fallouts that were sampled and measured. Even...
Thunderstorms and Volcanic Clouds
There are many similarities between eruption clouds and common convective clouds which lead to thunderstorms. This lecture calls attention to the comparison.

Direct sampling of volcanic clouds
Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...
