Hawaiian eruption A type of volcanic eruption that produces very fluid, mobile, basaltic lava, characterized by spectacular fire fountains, with little explosive activity. The lava flows that result are often formed by the accumulation of fire-fountained lava and are termed ‘spatter-fed flows’. Hawaiian-type eruptions produce a broad, low-angle cone (a shield volcano). Compare PELÉEAN ERUPTION; PLINIAN ERUPTION; STROMBOLIAN ERUPTION; SURTSEYAN ERUPTION; VESUVIAN ERUPTION; and VULCANIAN ERUPTION. hawaiite See ANDESITE; and BENMOREITE.
