Kilauea volcano began shooting lava into the air once again Tuesday on the Big Island of Hawaii. Kilauea, one of the world's most active volcanoes, has been erupting on and off for nearly two months since it burst to life on Dec.

Fountains from a vent of the Kilauea volcano on Hawaii's Big Island grew to more than 250 feet high Monday night.

Using a nearly 200-year record of lava chemistry from Kīlauea and Maunaloa, earth scientists from the University of Hawaiʻi at Mānoa and colleagues revealed that Hawaiʻi’s two most active volcanoes share a source of magma within the Hawaiian plume. Their discovery was published in the “ Journal of Petrology .”

The Hawaii Volcanoes National Park is home to the summits of two of the world’s most active volcanoes: Kilauea and Mauna Loa.
