A lava flow is an outpouring of lava during an effusive eruption Kilauea volcano put on another spectacular show friday night with lava fountaining in halemaumau crater reaching new heights for the latest eruption, which began nearly 10 months ago (an explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.)
