What will happen to the man that fell into the lava?
The Kilauea volcano in Hawaii erupting for a month, in photos and video you can see how the lava rises from the Ground through cracks in the asphalt and poured on the roads, but there are no victims — only destruction. But purely theoretically: what happens to the person who touches the liquid stone?
Lava flowing in Hawaii, has a temperature more than 1700 °C; this is five times hotter than the average home oven. Plunging his hand into the melt a temperature, you will not lose the limb immediately, but will get serious burns — “you will burn the nerve endings will burn subcutaneous fat” explains to the magazine The Verge David Damby, a chemist from the centre for the study of volcanoes with Geological service of the USA.
While the lava burns the body outside, says Demby, destroys you from the inside bubbling up from the close presence of molten rock water. But, unlike Gollum in the final film “the Lord of the rings: return of the king”, you are unlikely to dive into the lava, as the water. This liquid stone is too viscous. Volcanologist Janine Krippner adds that instead of having to dive into the lava, you’re more likely to sit or lie on its surface. In addition, the lava flows slowly (in most cases, you can just leave without going on the trot) and cools down quickly, and it formed a solid crust, which can even be run, what did this guy during the eruption of mount Etna. Do not try yourself!

In General, lava is dangerous and scary, but not too much. During the eruption there are things more dangerous — for example, volcanic mud flows, lahars. They usually have the consistency of wet concrete and gaining more speed than lava up to 200 km/h. They carry pieces of stone, cold and hot, water and pumice, and sometimes cover entire cities, killing the inhabitants — as it happened in 1985 in Colombia during the eruption of the volcano Nevado del Ruiz.
Still very dangerous pyroclastic flows is a mixture of high temperature volcanic gases, ash and rock. To escape from them impossible, the propagation speed sometimes reaches 700 km/h and the temperature is 700 °C. It is a pyroclastic flow destroyed in 79 the population of Pompeii and Herculaneum.
The USGS also recommends to roast over the lava flows marshmallows — even on very long sticks (believe that the answer of geologists, this curious Twitter user applies to the same question about kebabs). Here is what the representatives of the Agency: “Uh… No, it’s not safe (Please don’t do that!) If the fault comes from SO2 and H2S, the taste is NOT VERY. And if you add sulfuric acid, you will get a very spectacular reaction with the sugar.”
