From the mid-20th century to about 2010, Mauna Loa was less active, whereas Kīlauea was highly active. During this time, the chemistry of lava from Kīlauea became more similar to typical lava from Mauna Loa. Since 2010, researchers at University of Hawaiʻi at Mānoa and their colleagues observed a change in lava chemistry at Kīlauea.
