JB,

"I remember hearing about a village in Cameroon that was
essentially asphyxiated when a local volcano spewed out CO2
that blamketed the area. In that case, such a large quantity
of CO2 given off in a short period of time was toxic enough
to wipe out a village."

It was not a volcano, but rather a volcanic lake. On 21 August 1986, Lake Nyos in
Cameroon suffered a landslide which triggered the release of CO2 which was trapped under
the lake.

Approximately 1700 people were killed.

There are apparently a good number of other lakes around the world where this phenomenon
could occur again.

Just to keep things in perspective, I recall hearing about this incident while monitoring
shortwave!
