Cameroon state radio says that Mount Cameroon, a volcano in the country's southwest region, sent ashes and flames into the air in a brief explosion.
Cameroon Radio Television reported Monday that a violent explosion Friday lasted a couple of seconds and lightly injured two among the porters and guides on the mountain.
Mountain guide Peter Buma Linonge told state radio there were explosions, then flames burst into the air followed by ash.
Joseph Mokake, a resident of Buea, the town situated at the foot of the mountain, told The Associated Press there were tremors on Tuesday and Wednesday. He said he moved to a nearby town for safety. Residents say explosions and tremors serve as a precursor to a possible eruption.
Measuring just over 13,420 feet (4,090 meters) high, Mount Cameroon is an active volcano and the highest peak in West Africa.
