Why Mount Lewotobi Laki-Laki Matters
Located in East Nusa Tenggara, Mount Lewotobi Laki-Laki is one of Indonesia’s 120 active volcanoes. Standing at 1,584 meters, it’s part of a twin volcano system alongside the calmer Mount Lewotobi Perempuan. The name “Laki-Laki,” meaning “man” in Indonesian, reflects its more volatile nature compared to its “woman” counterpart. This volcano has a history of significant eruptions, with a deadly event in November 2024 claiming nine lives and injuring dozens. Its recent activity underscores Indonesia’s position on the Pacific Ring of Fire, a hotspot for seismic events.
The June 17 eruption spewed ash up to 11 kilometers (6.8 miles) high, creating a striking visual that was visible from cities 90 to 150 kilometers away. Authorities quickly raised the alert level to the highest tier, Level IV (Awas), and expanded the danger zone to 8 kilometers from the crater. Residents received warnings about potential lava flows, especially if heavy rainfall triggers dangerous lahars—mudflows of volcanic debris.
Impact on Local Communities and Travel
The eruption has disrupted life for those living near Mount Lewotobi Laki-Laki. Hundreds of villagers fled as ash blanketed nearby areas, with officials urging people to stay at least 7 to 8 kilometers away from the volcano’s summit. No casualties have been reported so far, a relief after the tragic November 2024 eruption. However, locals remain on edge, with warnings to wear masks to protect against ash inhalation and to watch for lahar risks during heavy rains.
Travelers face potential challenges too. The Australian government issued a red aviation alert due to the ash cloud’s threat to air traffic. While no flights have been canceled as of now, past eruptions in March and November 2024 caused significant disruptions, including delays to Bali-bound flights. Tourists planning trips to Flores or nearby islands should monitor updates closely.
Here’s a quick look at the current safety measures:
- Exclusion Zone: 7–8 km radius around the crater.
- Aviation Alert: Red alert for aircraft due to ash clouds.
- Public Advice: Wear masks, avoid ash exposure, and stay calm.
What’s Next for Mount Lewotobi Laki-Laki?
Seismic activity around Mount Lewotobi Laki-Laki remains intense, with over 50 volcanic earthquakes recorded in just two hours after the eruption—far above the usual 8 to 10 daily. This suggests the volcano could stay active for some time. Japan’s Meteorological Agency is also investigating whether the eruption might trigger a tsunami, though no immediate threat has been confirmed. The volcanology agency continues to monitor the situation, urging residents to follow local government directives.
For now, the focus is on keeping people safe and minimizing disruption. The volcano’s history shows it can erupt multiple times in a short period, as seen in 2024, so vigilance is key. Scientists are studying the ash cloud’s composition and movement to predict its impact on air quality and regional weather.
Stay Informed and Safe
The eruption of Mount Lewotobi Laki-Laki is a stark reminder of nature’s power and unpredictability. Whether you’re a local resident, a traveler, or simply fascinated by volcanic activity, staying updated is crucial. Check official sources like Indonesia’s volcanology agency or trusted news outlets for real-time information. If you’re in the area, follow evacuation orders and safety guidelines to protect yourself and your loved ones.
