Indonesia's Mount Ruang volcano has erupted, leading to the evacuation of over 12,000 residents amid fears of a potential tsunami from collapsing volcanic material. The eruption, reaching 5 kilometers high, has prompted authorities to raise the alert level, urging further evacuations within a 7-kilometer radius to prepare for possible explosive eruptions.

The highest warning level is in place as concerns about tsunamis persist, with residents and climbers advised to stay at least six kilometers away from the crater. The eruption has caused airport closures, ash spewing, and debris peppering nearby villages, highlighting the ongoing volcanic activity and the risks posed by Ruang's intensified tremors and potential pyroclastic flows.
