Chief of Mount Sinabung's monitoring post, Amien Putra, on Thursday, spoke of having warned local residents against entering the red zone on account of the volcano showing signs of heightened activity and a high possibility of an eruption at any time.
Residents are advised to stay outside a five-kilometer radius from the volcano's crater in the east and southeast and a four-km radius in the northeast, Putra stated.
"An alert status is still declared for Mount Sinabung. Hence, it will potentially erupt and spew (more) hot (ash) clouds,” Putra emphasized.
