Is it possible to survive lava

Skylights into lava tubes on pahoehoe flows are quite hot, and have to be approached from upwind. They are so hot that the air shimmers over them so they are hard to miss. They are dangerous not as much because of the radiant heat from the lava inside but because of the super-heated plume of air coming out. You have to be really careful that the wind doesn't shift, and many a volcanologist has gotten singed skin and hair when the wind changed.

An a'a flow is terrible to work near. Instead of a relatively continuous skin, a'a flows have discontinuous layers of clinker, and a huge amount of radiant heat escapes from between the clinker. Additionally, 'a'a flows tend to form open channels rather than lava tubes. The channels can sometimes have completely incandescent surfaces because they are flowing so fast that any skin that forms is immediately torn or sunk. We remember once flying over a large channel in a helicopter.

What would happen if you leaned a bit too far over the rim of a volcano and fell in? You would die, of course — but how? The question has garnered more scientific investigation than you might expect. As reported in December, lava's high density and resistance to flow suggest a person would smack onto the surface of a lava pit rather than sinking into it. The real danger comes from volcanic mudflows , also called lahars, says Krippner. In , a lahar caused by the Nevado del Ruiz volcano in Colombia submerged an entire town, killing 25, people.

In , resourceful residents of the village of Catania fought back against the all-destructive force of molten lava.

The residents of nearby Paterno were not pleased. They believed the diversion pointed the lava directly at their own community and decided to stop Catania's attempts. The breach sealed up and the lava continued flowing toward Catania, destroying a large portion of the town.

It was the modern start to what Dr Shannon Nawotniak, a professor of geology at Idaho State University, calls a "spectacularly poor success rate" of stopping lava. At temperatures of about 1,C 1,F , lava destroys whatever it touches. Its path is notoriously hard to predict. The ability to impede or redirect lava largely depends on location, resources and luck. Here are four strategies:.

Before he was a general in World War Two, George S Patton designed a different kind of military campaign - a bombing run on Hawaii's Mauna Loa, the largest volcano on Earth, as it erupted in As the lava began flowing at a rate of one mile 1. Lava tubes are cooled and hardened outer crusts of lava which provide insulation for the faster-flowing, molten rock inside. Such a conduit enables lava to move farther and faster. In theory, bombs would destroy the lava tubes, robbing lava of an easy transport channel and exposing more of the lava to the air, slowing and cooling it further.

But in practice, while bombs created craters in parts of the tubes, they were soon filled again by the lava. Hilo was instead saved when Mauna Loa stopped erupting. Later tests by the US Air Force suggested newer, larger bombs could make more of a difference if they were targeted at the most vulnerable sections of the flow.
