Shield volcanoes can produce pyrcoclastic flows, but it is rare. Shield volcanoes are fed by low-viscosity basaltic lava with a low gas content. The means that most eruptions are either non exposive or have a very low-grade explosivity. An eruption needs to be explosive to produce pyroclastic flows. However, records show that Kilauea has produced explosive eruptions with pyroclastic flows. The explosions appear to have been the result of groundwater seeping into the magma chamber.

How are pyroclastic flows formed?
There are a number of ways in which pyroclastic flows occur and the first follows a Plinian eruption. If a fountain collapse of its eruption column occurs the jet is not able to heat the air sufficiently and lack of convection causes the plume to fall rather than shoot upward and flow down the mountain. The second is the same type of collapse after a vulcanian eruption in which a gas cloud is created that is denser than the air around it and this turns into a pyroclastic low. Other ways include a lava dome suffering a gravitational collapse, the mouth of a vent in a volcano frothing when the erupted lava degasses and when a section of a volcano collapses and a directional burst occurs.

How far do you need to be away from a volcanoe so you dont get burnt?
Depends on if the volcano is erupting or not. If it's not then you could go anywhere you wanted on the volcano. If it's erupting stay out of pyroclastic flow and about 30 feet from lava and you won't feel it that much. But be careful because lava moves quickly at times.

How can people protect themselves from a volcano?
dont live near a volcano
Which volcano does not erupts?
Dormant volcanoes dont erupt, if you are looking for a single volcano, just say the Bola volcano
How do you get in volcano?
well you dont want to get in a volcano unless it is EXTINCT. If it is then sometimes there are some people who you pay to take you inside a volcano
