No, I don't have experience in this, and hopefully I will never need to do so either.
But I thought it would be a good idea nonetheless.
Generally when people think of a volcano they will probably think of either Mount St Helens or a Kilauea type eruption.
With Kilauea, it is generally going to be a short term survival problem, as during the long run there is not very much hazard, although if you happen
to be in the wrong place, the area in which you live will be destroyed.
This house was in the way of a Kilauea eruption:
The main problem is the lava flows, which while very hot (obviously) are generally quite slow, and as such do not prove to be a massive problem with
getting way from. They have little energy and will generally follow a valley or similar down to the ocean, or they will solidify first. There are
also hazards associated with the lava hitting the sea, such as a hydrothermal type blast, which can potentially throw up bits of lava. Or the area
will be unstable, and while it may look solid, it is likely not to be a few centimetres down.
The more hazardous type is the Mt St Helens type, explosive, sending ash high into the sky, and generally not somewhere you would want to be near.
The main hazard close up, is the Pyroclastic flow, which is basically hot rocks, ash and gases moving very fast down the side of the volcano. It
cannot easily be outrun using a road vehicle for example.
A Pyroclastic surge is slightly different, in that it has less rock, but it can potentially flow over the top of a hill for example.
After the eruption is over, the ash fallout is a hazard, as this website demonstrates.
What to do in volcanic ashfall
A lahar is volcanic ash and mud, which, when combined with rain can flow down the side of a volcano and flow with devastating effect through a any
Lahars have the consistency of concrete: fluid when moving, then solid when stopped. Lahars can be huge: the Osceola lahar produced 5,600 years
ago by Mount Rainier in Washington produced a wall of mud 180 m (600 feet) deep in the White River canyon and extends over an area of over 320
Lahars can be extremely dangerous, because of their energy and speed. Large lahars can flow several dozen meters per second and can flow for many
kilometres, causing catastrophic destruction in their path. The lahars from the Nevado del Ruiz eruption in Colombia in 1985 killed an estimated
25,000 in the city of Armero, buried under 8 m (26 ft) of mud and debris. The 1953 Tangiwai disaster in New Zealand was caused by a lahar.
