(CNN) -- Africa's most active volcano, Mount Nyamuragira in the Democratic Republic of Congo, erupted early Saturday, spewing lava off its southern flank, the Congolese Wildlife Authority reported.
Rangers in Virunga National Park reported hearing a loud explosion at 3:45 a.m. and then seeing lava flowing from the crater of the 10,333-foot volcano.
Virunga National Park is also home to 200 endangered mountain gorillas, but they live on the slopes of the Mikena volcano to the east of Nyamuragira.
The Smithsonian Museum of Natural History calls Nyamuragira the continent's most active volcano, with 42 eruptions since 1885. Its most recent eruption ended in December 2006.
