Which type of volcanic eruption is characterized by gentle effusions of highly fluid, basaltic lava with minimal explosive activity, resembling fountain-like lava streams?

💡 Solution & Explanation

Hawaiian eruptions are characterized by effusive outpourings of highly fluid, low-viscosity basaltic lava that form gentle fountain-like streams with very little explosive activity. Unlike viscous and gas-rich explosive eruptions such as Vulcanian or Peléean, Hawaiian flows spread widely before solidifying. Shield volcanoes, such as Mauna Loa, are predominantly formed by these continuous basaltic effusions.
