[edit] Model
We can model a pyroclastic surge by using the white steam from an ultrasonic humidifier. The water droplets and the air are fairly warm, yet the steam flows downward to form a ground-hugging density current. Air has a density of around 1.2 kg m3, but if the added mass due to suspended particles is significant, then even though the particles remain suspended, they drag down the air between them as they fall. --Wjbeaty 21:09, 6 August 2006 (UTC)

Seminal work on the subject? Removed nomenclature? Pyroclastic density currents!!! —Preceding unsigned comment added by Russjass (talk • contribs) 14:24, 12 May 2008 (UTC)
