Tsunami alert after a volcano in Indonesia has several big eruptions and thousands are told to leave

JAKARTA, Indonesia (AP) — Indonesian authorities issued a tsunami alert Wednesday after eruptions at Ruang mountain sent ash thousands of feet high. Officials ordered more than 11,000 people to leave the area.

The volcano on the northern side of Sulawesi island had at least five large eruptions in the past 24 hours, Indonesia’s Center for Volcanology and Geological Disaster Mitigation said. Authorities raised their volcano alert to its highest level.

At least 800 residents left the area earlier Wednesday.

Indonesia, an archipelago of 270 million people, has 120 active volcanoes. It is prone to volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
