Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.

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).

Molten rock began shooting from the volcano before dawn on Monday when fissures opened in the caldera floor and propelled lava 295 feet into the air. The red liquid formed tall fountains and then spread across 650 acres. The Hawaiian Volcano Observatory estimated the lava was about 1 yard (1 meter) thick.
