Mount Lewotobi Indonesia Erupts Six-Mile Ash Cloud Sparks Aviation Red Alert

Mount Lewotobi in Indonesia erupted on June 17, 2025, sending a massive ash cloud approximately six miles (10,000 meters) high into the sky, prompting a red aviation alert from the Australian government. The eruption has raised fears of a potential tsunami, leading Japan's Meteorological Agency to investigate the situation. Authorities have warned locals and tourists to stay at least seven to eight kilometers away from the volcano due to risks including pyroclastic flows and possible lava flows if it rains. This volcano, part of Indonesia's 120 active volcanoes located on the Pacific Ring of Fire, has shown increased activity over recent days, and previous eruptions have caused fatalities and property damage. Officials urged calm and adherence to local government instructions as emergency responses continue. The eruption's impact on air travel and nearby communities remains significant as investigations and monitoring proceed.
