Mount Lewotobi Laki-Laki Eruption Caught on Camera!

In a dramatic display of nature’s power, Mount Lewotobi Laki-laki on Indonesia’s Flores Island erupted on June 17, 2025, sending a towering ash column soaring into the sky and prompting immediate evacuations and widespread flight disruptions. The eruption, which occurred at 17:35 WITA (Western Indonesian Time), has once again highlighted the challenges faced by Indonesia, a country with over 120 active volcanoes, as it navigates life along the volatile Pacific “Ring of Fire.”

A Sudden Eruption Shakes Flores Island

Mount Lewotobi Laki-laki, a 1,584-meter-high volcano located in the East Nusa Tenggara province, erupted with startling force on Tuesday, June 17, 2025. The eruption sent an ash plume billowing into the atmosphere, with reports indicating heights ranging from 10 to 16 kilometers, depending on the source. The sheer scale of the eruption was visible from as far as 90 to 150 kilometers away, as ash rained down on nearby villages and communities, creating a scene described by one evacuee as “like snow falling from the sky.”

The event was preceded by intense seismic activity, with 50 deep volcanic quakes recorded in just two hours leading up to the eruption. This surge in activity prompted Indonesian authorities to raise the volcano’s alert level to its highest status within a four-tiered system, signaling an imminent and severe threat. The danger zone around the volcano was expanded to an 8-kilometer radius, with a specific 7-kilometer exclusion zone in the southwest-northeast sector, urging residents to evacuate immediately.

Impact on Local Communities

The eruption left no time for hesitation. Over 800 residents from two nearby villages were swiftly evacuated to safer areas, with at least 450 families relocated to emergency shelters. “We grabbed what we could and left,” one evacuee recounted. “The ground was shaking, and the ash was everywhere. It was terrifying.” The evacuation was particularly urgent due to warnings of potential lava flows and the risk of hazardous lahar floods—mudflows triggered by volcanic ash mixing with heavy rainfall—especially near rivers. Authorities have advised residents to wear masks to protect against ashfall, which can cause respiratory issues, and to remain vigilant as the volcano continues to show signs of unrest.

Local authorities have been working tirelessly to provide shelter and support to the displaced. Emergency shelters have been set up in nearby towns, and aid organizations are mobilizing to ensure access to food, water, and medical assistance. Despite the chaos, there have been no reported casualties, a testament to the swift response of Indonesia’s disaster management teams, which are well-versed in handling volcanic eruptions.

Flight Chaos Across the Region

The eruption’s impact extended far beyond the immediate vicinity of the volcano. The massive ash cloud posed a significant threat to aviation, leading to the closure of Fransiskus Xaverius Seda Airport in Maumere, Flores, until Thursday morning, June 19, 2025. In Bali, a major tourist hub, Ngurah Rai Airport was forced to cancel 32 flights, affecting both domestic and international routes. Major airlines, including Jetstar, Virgin Australia, Singapore Airlines, Air India, Air New Zealand, and Qantas, reported cancellations or delays. Air Asia also had to cancel flights to nine airports in East Malaysia and Brunei, further disrupting regional travel.

The disruptions have been particularly hard-hitting for Bali’s tourism industry, which relies heavily on air travel during peak seasons. “This is peak season for us,” a hotel manager in Bali lamented. “With flights cancelled, we’re seeing a lot of last-minute cancellations from tourists. It’s a big hit to our business.” The closure of the airport in Manado, another affected area, added to the travel chaos, with widespread infrastructural damage and power outages reported in some regions.

A History of Volcanic Activity

This is not the first time Mount Lewotobi Laki-laki has erupted with devastating consequences. In November 2024, the volcano unleashed a deadly eruption that claimed nine lives, injured dozens, and forced thousands to evacuate while disrupting scores of international flights. That event served as a grim reminder of the risks faced by communities living in the shadow of active volcanoes. The current eruption, while less deadly so far, has caused significant disruption and underscores the ongoing challenges of living in one of the world’s most volcanically active regions.

Indonesia, situated along the Pacific “Ring of Fire,” is home to over 120 active volcanoes, more than any other country. Volcanic eruptions rank as the third most frequent natural disaster in Indonesia, after floods and earthquakes, and are second only to earthquakes in terms of casualties. Mount Lewotobi Laki-laki is part of a twin-peak formation, with its calmer counterpart, Lewotobi Perempuan, meaning “woman” in Indonesian, while Laki-laki translates to “man.” This cultural naming reflects the deep connection between the local population and their natural surroundings, even as they face constant threats from volcanic activity.

Ongoing Risks and Vigilance

As of Wednesday morning, June 18, 2025, the volcano continued to exhibit signs of unrest, with tremors and smaller eruptions detected throughout the day. The volcano erupted six times since late Sunday night, coughing lava, rocks, and ashes up to 3 kilometers into the air. Authorities remain on high alert, closely monitoring the situation to ensure public safety. The potential for further eruptions, coupled with the risk of heavy rainfall triggering lahar floods, keeps emergency responders on edge. Residents and travelers have been urged to stay informed through official channels and to remain cautious.

A Call for Preparedness

The eruption of Mount Lewotobi Laki-laki serves as a stark reminder of the delicate balance between human life and the forces of nature. For the residents of Flores Island, living in the shadow of an active volcano is a daily reality, one that requires constant vigilance and preparedness. While this latest eruption has not resulted in loss of life, it has disrupted communities and economies, underscoring the need for robust disaster management strategies.

Indonesia’s experience with volcanic eruptions is a testament to its resilience, but it also highlights the importance of continued investment in early warning systems, evacuation protocols, and community education. As climate change potentially influences volcanic activity, scientists and policymakers are increasingly focused on understanding and mitigating these risks. For now, the focus remains on supporting those affected by this latest eruption and ensuring that lessons learned are applied to future events.

The eruption of Mount Lewotobi Laki-laki on June 17, 2025, may have been a fleeting moment in geological time, but its impact on the lives of those in its path will be felt for days, if not weeks, to come. As the ash settles and life begins to return to normal, the people of Flores Island and beyond will continue to live with the knowledge that their home is one of the most dynamic and dangerous places on Earth.
