Best Answer

In addition to suffocating ash and flowing lava, pyroclastic flows are probably the most dangerous feature of some volcanoes. Pyroclastic flows are currents of extremely hot gases and rocks that flow down and away from the slopes of volcanoes. They travel at speeds has high as 450 mph, and the temperature of the gas and rock can reach more than 1800° F (1000° C).

Is Krakatoa dangerous?

Krakatoa has many hazards because it is a subduction volcano. Lava flow is of course a hazard for the area surrounding the volcano but hazards for areas further away include volcanic gases which produce acid rain and there can be volcanic debris that has the ability to travel quite far from the source. Other hazards can include ground cracks and tsunamis due to the sheer strength a volcanic eruption can expel.
