STORY: The Center for Volcanology and Geological Hazard Mitigation (PVMBG) had warned the residents of Tagulandang island that a tsunami could be triggered by volcanic material collapsing into the ocean. The warning, issued on Tuesday morning, remained in placed as of the afternoon. The agency raised the alert status of Ruang to the highest level following the early morning eruption, urging residents not to go near the volcano. Footage captured by an eyewitness showed fiery red lava flowing from Ruang and strikes of lightning flashing above its crater. Indonesia straddles the so-called "Pacific Ring of Fire," an area of high seismic activity where multiple tectonic plates meet.
