The magma has changed a great deal over the years. One example is the silica weight percent peaked at 100‚000 and 200‚000 years and was the lowest in the last eruption. This indicates that Hawaii might have had more felsic lavas and more explosive eruptions 100 and 200 thousand years ago than in 1959. The weight percent of K2O and Na2O of the lava has also fluctuated throughout the years.These changes are the result of the magma changing from andesite rich lava to more basalt rich over time. The

extremely large‚ measuring 5-6 meters in diameter and landing more than 500 meters from the volcanic vent.

Secondary Cone – Secondary cones build up around secondary vents on larger volcanoes.

They usually are created of eruptions from a single vent‚ and are composed solely of lava remnants. Cinders of lava‚ blown into the
