What had been low-level lava flows since Thursday morning became more vigorous fountaining Friday evening, according to the U.S. Geological Survey’s Hawaii Volcano Observatory.

Lava is erupting from Hawaii’s Kilauea volcano for the second straight day. The eruption has stayed within Kilauea’s summit caldera inside Hawaii Volcanoes National Park and no homes are threatened.

One of the world’s most active volcanoes erupted on Monday after a three-month hiatus, spewing bright orange lava as high as 300 feet, according to the United States Geological Survey (USGS).
