One of the greatest shows on Earth has been going on now for several months in Hawaii, where the Kīlauea volcano at Hawai'i Volcanoes National Park has been erupting since late December. The Kīlauea volcano is the most active volcano on Earth. It's also a relatively safe volcano in that it spends most of its time simmering and bubbling without any spectacularly explosive eruptions. But lately it has been putting on some incredible shows of lava fountains, with one glowing string of magma soaring about 1,000 feet in the air, a truly spectacular sight to see. To understand what's going on with Kīlauea and what danger it poses, we're joined today by Matt Patrick, a research geologist with the Hawaiian Volcano Observatory.
