In the movie "Volcano" basaltic lava flows are shown running down flat streets at speeds faster than humans could run. From your knowledge of magma viscosity, is this realistic?
A) There is no way of knowing because basaltic magmas can have viscosities similar to water or higher depending on temperature and fluids, and thus there isn't enough information.
B) No, the viscosity of basaltic magma is much higher than water, and thus, would flow much faster than water.
C) Yes, the viscosity of basalt magma is similar to water so it would flow at comparable rates.
D) No, the viscosity of basaltic magma is much higher than water, and thus, would flow much slower than water.
