Lava is a mixture of molten rock, solid crystals, and gas, with a wide range in compositions, flow velocities, and flow lengths and thicknesses. Lava flows can erupt effusively from vents or fissures, or in strombolian explosions or lava fountains. Viscous lava can result in thick flows that move slowly and hot, low-viscosity flows can travel far from the vent, especially when they are insulated in lava tubes and fracture networks. Hazards include rapid lava flows, explosions, pyroclastic flows when lava flow fronts collapse, lava delta collapse, volcanic gas, rock falls, igniting fires, and falling through the cooled crust of lava.
