所以这不是火山(见内），而是地下的天然气燃烧三个碳的丙烷，燃烧变成无味的二氧化碳。

火山爆发时是有sulfur dioxide (SO₂)和hydrogen sulfide （H2S) （臭鸡蛋的味）所以有硫化物味。hydrogen fluoride是用来在玻璃上刻字的，如实验室里量杯上的刻度。所以要远离火山。

Ninety-nine percent of the gas molecules emitted during a volcanic eruption are water vapor (H₂O), carbon dioxide (CO₂), and sulfur dioxide (SO₂). The remaining one percent is comprised of small amounts of , carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species.
