Airport service has been stopped, people have been evacuated¹ and officials are warning of a tsunami² risk after a series of violent eruptions³ this week from an Indonesian volcano.



The 750-foot Ruang volcano, located on a remote island in the province of North Sulawesi in Indonesia has erupted multiples times since Tuesday, spewing columns of lava⁴, rock and ash as far as two miles into the sky.



Indonesia, a country in Southeast Asia located between the Indian and Pacific oceans consisting of over 17,000 islands, is the fourth-largest country in the world by population.



Tsunami warning issued for fears of volcano collapse⁵

Officials said the volcano alert had been raised to the highest level Wednesday, and warned people to not go within roughly 4 miles of the peak due to fears part of the volcano could collapse into the water and trigger a tsunami.



The volcano previously⁶ erupted and collapsed⁷ into the water in 1871, which killed roughly 400 people.



Over 800 local residents have been evacuated, including hundreds from the Laingpatehi and Pumpente villages, Indonesia's disaster agency BNPB announced.
