Prometheus is the site of two volcanic eruption plumes : a small, sulfur-rich plume erupting from the magma-source vent at the eastern end of the flow field and a-tall,-rich dust plume erupting from the active flow front at the other end.

In each of these cases, the volcanic plumes emanated from different parts of Masubi Fluctus, providing further evidence that dust plumes like the one at Masubi result from the rapid sublimation of surficial sulfur dioxide frost by warm, advancing lava flow fronts, rather than erupting from the primary volcanic vent.

In a rare firefight in downtown Baghdad recently, I found myself between the close crack of a gun and the little dust plume where the bullet hit . ( It is either scrupulousness, since I have no clue whether it was me or something else the gunman was aiming at, or dead denial that prevents me from writing that I was shot at .)
