我是一个火山学家,我有喷发的火山。首先,火山学家实际上几乎从来不穿那些西装。热量几乎从不重要的风险情况下,我们的工作。危害通常被弹道冲击的机会,或被毒气毒死。你经常看到那些套装的原因是,他们在电视上看起来很酷。我知道凯蒂和莫里斯约翰一般穿着它们,但他们的目标是尽可能接近爆炸喷发,尽可能频繁,尽可能长时间地。这种策略会导致死亡。这是一个悲剧,当约翰(41人)被杀Unzen但不完全是一个令人惊讶的人,回想起来。现代火山学家倾向于更谨慎,你可能会说,火山学的英雄时代已经结束了。当你在火山爆发,一些主要的事情你可以做什么来减少风险:1。 Wear a helmet. This would have saved lives at Galeras. 2. Reduce the amount of time you spend in the hazard zone. This means you need to work quickly, which often means carry less and don't wear silly protective gear like heat suits. 3. Wear a gas mask, usually with SO2 scrubber cartridge. Ever try to jog up a hill in one of these? It becomes hard to breathe, and the mask quickly fills up with condensation from your breath. Communication through a radio or otherwise is hindered. Everything takes longer, so sometimes the masks are left off in the interest of #2. 4. Increase your situational awareness. Maintain communications with someone who is watching data from instruments such as seismometers and tiltmeters. Also, make sure you have unobstructed vision so that you can potentially step out of the way of lava bombs which are falling towards you. Again, PPE such as a heat suit or even a gas mask can work against this. As for the idea of "picking up" lava with your hands, remember that lava is extremely viscous, so it takes quite a lot of force to pull a sample out of a flow. The colder lavas to which you refer are even more viscous than hotter lavas. Anyway, I doubt there are any gloves that can deal with prolonged contact with a 650C fluid. (Remember that fluids and solids are far more conductive than a gas and will transfer far more heat.) I think trying to sample lava with hands would be far more "awkward" than using a pole, which is really quite a simple, easy way to do it. Edit: I just thought of another reason volcanologists can't dress like firefighters. Expense. Volcanologists have an extremely hard time getting sufficient funding. I actually asked for an SCBA for my work in the fumarolic ice caves of Mt Erebus, where CO2 is high. We couldn't afford it on our grant. Instead, I just carefully monitor gas levels and there are caves which I cannot enter because we read dangerous levels of gas at the entrances. Edit: I highly recommend that anyone interested in this subject read No Apparent Danger and Volcano Cowboys.
