(Fig. 2.14) Hawaiian Eruption.
Hawaiian eruptions are characterized by lava-effusion (an eruption of lava which most commonly gives rise to lava flows). Most frequently, they begin with lava-fountaining, sometimes cones of fragments are formed.
Utmost hot magma which has a very low percentage of silica will flow outside the volcano in very fluid streams. Hawaiian eruptions result in vast, gentle volcanoes known as shields or shield volcanoes. Note that the Hawaiian volcanoes are associated with a hot spot.
