Hi,
a friend and I went to Italy this year visiting Stromboli (which
is closed to the public now) and climbed Vulcano. We became more
curious about vulcanism and my friend bought a book that sais,
Vulcano was emitting TONS of gas per day. Now we've seen the
fumaroles we believe this was quite unlikely - a ton of gas is
such an enormous amount. Maybe this was correct for a longer
time, maybe a month or a year.
Can anybody here say something about this?
Thank you!

Most active volcanoes have numerous vents and fractures. You probably
didn't see them all. And a ton of gas coming out of a volcano is a very
small amount. It would dissipate fairly rapidly, depending on wind
conditions. |

Do a short calculation:
CO2 has a density of about 2kg/m3 (at 1 bar pressure). This means that
500m3 have 1 ton.
500m3/d is 21m3/h or 6 l/sec. That's not so much after all.
Cheers, Christof
