WebViscosity is the internal friction, or resistance to flow—or how “thick and sticky” or “thin and runny” a lava is. Lavas with low viscosity such as those erupted at Kilauea in Hawai’i Volcanoes National Park flow easily, with flow fronts that move up to 6 miles (10 km) per hour. Speeds in channels or lava tubes on steep slopes can ... WebThe speed of a magma flow depends on its viscosity – that is, its resistance to flow – which in turn depends upon how much water and silica are in the magma itself. ... viscous magma with high gas content. This combination is explosive because the gases cannot easily boil out. The gases remain trapped in the magma until the pressure in the ...
