In 1868, and an eruption from Mauna Loa caused the largest earthquake in Hawaii, registering as a magnitude 8 by modern methods. The lava flow of 1855-1856 is said to be one of the greatest flows ever seen by modern observers.
Shield volcanoes are formed when a large amount of free-flowing lava spills from a vent and spreads widely. The lava gradually builds up a low, broad, dome-shaped mountain. The famous Mauna Loa in Hawaii is a shield volcano.ava is the name for magma that has reached the earth's surface. When lava comes to the surface, it is red hot and may have a temperature of more than 2012 F. (1100 C). Highly fluid lava flows rapidly down a volcano's slopes. Sticky lava flows more slowly.
