Fluid #basalt #flows can extend tens of kilometers from an #erupting vent. The leading edges of basalt flows can #travel as #fast as 10 km/h (6 mph) on steep slopes but they typically advance less than 1 km/h (0.27 m/s or about 1 ft/s) on gentle slopes.
But when basalt lava flows are confined within a channel or lava tube on a steep slope, the main body of the flow can reach velocities >30 km/h (19 mph).
