Volcanic Eruption at Mount Lewotobi Laki Laki Forces Thousands to Flee in Indonesia
In a dramatic and tragic turn of events, the eruption of Mount Lewotobi Laki Laki, a volcano located on Indonesia’s remote Flores Island, has resulted in widespread destruction, displacing thousands and causing significant loss of life. The eruption, which began late last week, has intensified over the past few days, creating hazardous conditions and forcing authorities to declare a state of emergency. With volcanic ash rising as high as 6,500 feet (2,000 meters) into the sky, local communities are grappling with the aftermath of the disaster.
Mount Lewotobi Laki Laki Eruption Escalates, Devastating Local Communities
The eruption of Mount Lewotobi Laki Laki has been nothing short of catastrophic. Thick plumes of volcanic ash and debris have blanketed nearby villages, causing extensive damage to homes, infrastructure, and even a convent. The eruptions began on a smaller scale last week, but after midnight on Monday, the situation worsened dramatically. According to Firman Yosef, an official at the Lewotobi Laki Laki monitoring post, hot ash began raining down on surrounding areas, igniting fires and destroying properties, including the convent in Hokeng village.
In addition to property damage, the eruptions have tragically claimed at least six lives. A nun from the affected convent was reported dead, and another remains missing. “Under a rain of volcanic ash in the darkness, our nuns fled in terror,” stated Agusta Palma, the director of the Saint Gabriel Foundation. The volcanic material was propelled as far as 3.7 miles (6 kilometers) from the volcano’s crater, affecting multiple communities.
Rising Threat: Expanding Danger Zone and Increased Alert Levels
In response to the escalating eruptions, Indonesia’s National Disaster Management Agency has raised the alert status for Mount Lewotobi Laki Laki to its highest level. Authorities have also expanded the exclusion zone, now extending to a 4.3-mile (7-kilometer) radius around the volcano. This increased danger zone affects a number of villages, including those in Wulanggitang District, where nearly 10,000 residents are directly impacted.
Local authorities are scrambling to provide shelter for the displaced, with temporary evacuation centers set up in schools and other public buildings. As volcanic ash continues to fall, residents of the affected areas are facing ongoing threats of further eruptions and fires.
Devastation in Neighboring Districts: Widespread Ashfall and Structural Damage
The eruption has not been limited to a single village. Entire communities across several districts, including Ile Bura and Titehena, are grappling with severe volcanic ash fallout. Villages in these areas have seen homes and streets buried under several inches of volcanic debris. In some villages, the ash is so deep that it has reached rooftop levels, leaving entire communities in peril.
Rescue operations are underway, but officials have warned that many people could still be trapped under the rubble of collapsed homes. The full extent of the damage is yet to be determined, but early reports suggest widespread destruction. Video footage and photos circulating on social media show buildings engulfed in flames, with thick clouds of volcanic ash shrouding entire towns.
Indonesia’s Volcanic Activity: A History of Destruction
Mount Lewotobi Laki Laki’s eruption is just the latest in a series of volcanic events to strike Indonesia, a nation situated along the volatile “Ring of Fire,a region surrounding the Pacific Ocean that experiences high levels of volcanic and seismic activity. This year alone, Indonesia has witnessed multiple eruptions, including those of Mount Ibu and the Ruang volcano, both of which forced mass evacuations.
Just days before Lewotobi‘s eruption, Mount Marapi in West Sumatra erupted, sending columns of ash into the air, though fortunately without causing fatalities. However, a December 2023 eruption of Mount Marapi claimed at least 23 lives, highlighting the deadly potential of Indonesia’s volcanoes.
One of the world’s most volcanically active nations, Indonesia is home to more than 120 active volcanoes. The nation’s residents live with the constant threat of eruptions, earthquakes, and landslides, a result of the tectonic plate movements that occur within the Ring of Fire.
Ongoing Monitoring and Relief Efforts
As the situation continues to evolve, Indonesia’s volcano monitoring agencies and disaster response teams are on high alert. While volcanic activity at Mount Lewotobi Laki Laki may persist, officials are working tirelessly to ensure the safety of residents, providing emergency relief and evacuating those in danger.
Meanwhile, Indonesia’s National Disaster Management Agency is continuing its search for survivors and is preparing for the possibility of further eruptions. With thousands of people displaced and at least 10,000 affected, the coming days will be critical in assessing the full impact of the disaster and providing aid to those in need.
The eruption of Mount Lewotobi Laki Laki serves as a stark reminder of Indonesia’s vulnerability to natural disasters. As the country continues to deal with the fallout from this latest volcanic eruption, the resilience of its people will be tested once again.
Lewotobi Volcano: A Detailed Overview of Its Eruptive History and Geological Significance
Lewotobi is an active andesitic volcano located on the eastern end of Flores Island, in Indonesia. Located in the center of the Pacific “Ring of Fire,” this island is home to a large number of active volcanoes, many of which have shaped the topography of the area and had an impact on the local populace. Lewotobi’s volcanic activity is closely monitored by the Indonesian government due to its explosive eruptions, which can have devastating effects on nearby communities.
The volcano consists of two distinct peaks, Lewotobi Lakilaki and Lewotobi Perampuan, separated by a 2-kilometer saddle. Each peak is notable for its own volcanic crater and unique eruption history. The following sections will explore the physical characteristics of Lewotobi Volcano, its past eruptions, the geological features of the surrounding region, and the risks associated with future activity.
Geological Overview of Lewotobi Volcano
Lewotobi Volcano is classified as an andesitic stratovolcano. Andesitic volcanoes are known for their explosive eruptions due to the composition of the magma beneath them. This type of magma is more viscous than basaltic magma, which makes it more likely to trap gas and lead to pressure build-up. Violent eruptions occur when this pressure is finally released. Lewotobi is a prime example of this phenomenon, as its eruptions have historically been marked by significant explosive activity.
The volcano is actually composed of two separate volcanic peaks: Lewotobi Lakilaki and Lewotobi Perampuan. These two peaks are separated by a 2-kilometer-wide saddle, with a difference in elevation of 119 meters (1584 meters for Lewotobi Lakilaki and 1703 meters for Lewotobi Perampuan). Both peaks contain their own craters, with the crater at Lewotobi Lakilaki being open to the north. The crater at Lewotobi Lakilaki has a diameter of 400 meters, while the one at Lewotobi Perampuan is much larger, with a width of approximately 700 meters.
The volcanic history of Lewotobi is notable for its series of explosive magmatic eruptions, with intervals between eruptions typically ranging from 1 to 29 years. This unpredictable nature of the volcano has made it a subject of extensive scientific study, as volcanologists work to understand the factors that lead to such erratic eruption patterns.
Recent Volcanic Activity and Eruptions at Lewotobi
The 2024 Eruption: A Massive Event
On November 4, 2024, Lewotobi Volcano erupted in what has been described as a large and powerful event. The eruption produced massive ash emissions that reached an astounding altitude of 40,000 feet (approximately 12,000 meters) into the atmosphere. This eruption has had a significant impact on nearby communities and disrupted air travel in the region. The ash cloud from the eruption blanketed nearby villages, causing damage to homes, agricultural land, and infrastructure.
The scale of this eruption places it among the most significant in recent years for Lewotobi. Due to the intensity of the eruption, local authorities raised the volcano’s alert level to the highest possible level, warning residents to stay at least several kilometers away from the active crater. The impact of this eruption serves as a reminder of the risks that Lewotobi Volcano poses to the surrounding population, especially given the volcano’s history of explosive events.
Unrest in 2015: Rising Seismic Activity
In March 2015, Lewotobi experienced a period of volcanic unrest marked by an increase in volcanic seismic activity. Starting on March 13, 2015, the frequency of volcanic earthquakes around the volcano increased significantly, which prompted authorities to raise the volcano’s alert level. On March 17, the alert level was increased from its normal status to “waspada” (Level 2), which is considered an early warning stage for potential volcanic eruptions.
As a precaution, a 1-kilometer exclusion zone was established around the crater to ensure the safety of local communities. The increased seismic activity during this period served as a reminder of Lewotobi’s potential for explosive eruptions, and volcanologists closely monitored the situation. Fortunately, no major eruptions occurred during this period, and the increased seismic activity gradually subsided.
The 2011 Unrest: Intensification of Seismic Activity
A similar unrest occurred at Lewotobi Volcano in 2011. In August of that year, seismic activity around the volcano saw a sharp increase, with the number of shallow volcanic earthquakes rising from the typical 5-10 per day to more than 50 on certain days. This sudden increase in seismic activity raised concerns among experts, prompting a reevaluation of the volcanic threat.
On August 31, 2011, authorities raised the alert status of Lewotobi to Level 2 (out of a maximum of 4), and a 1-kilometer exclusion zone was placed around the volcano. Seismic monitoring and the increased number of volcanic earthquakes indicated a possibility of an impending eruption. Although no major eruption occurred during this unrest period, the heightened activity demonstrated Lewotobi’s potential for significant volcanic events.
The 2003 Eruption: Ashfall and Ongoing Activity
Lewotobi’s eruptive history includes a notable event in 2003. The eruption on May 30, 2003, saw ash emissions that reached a height of 200 meters above the summit of the volcano. This eruption was followed by continued volcanic activity in June and July, with ashfall affecting nearby villages, including Bawalatang, Duang, and Boru. The eruptions also had an impact on the local economy, as agricultural fields and crops were covered with ash, affecting food production in the area.
Seismic activity associated with the 2003 eruption continued until September of that year, but there were no reported fatalities. However, the eruption highlighted the potential for damage to local infrastructure and communities, especially given the frequency of eruptions at Lewotobi.
The 2002 Eruption: A Brief but Explosive Event
A smaller yet significant eruption took place in October 2002. On October 12, 2002, Lewotobi experienced an explosive event that resulted in the ejection of volcanic material. Though the eruption did not reach the same scale as the 2003 or 2024 eruptions, it nonetheless served as a reminder of the ongoing volcanic activity in the region. The eruption, while not causing widespread destruction, was a stark indication of the volcano’s persistent potential for violent eruptions.
The 1999 Eruption: A Devastating Impact
One of Lewotobi’s most significant eruptions in recent decades occurred in 1999. On March 31, 1999, rumbling and ash emissions began, signaling the start of increased volcanic activity. The situation escalated on July 1, 1999, when a major eruption occurred. This eruption was marked by glowing lava ejected up to a 500-meter radius from the volcano, causing forest fires that spread up to 2.5 kilometers north of the summit. The eruption also produced substantial ashfall, which affected villages as far as 8 kilometers from the volcano. Affected areas included Boru, Bawalatang, and Watukubu.
The 1999 eruption caused significant damage to agricultural fields, homes, and infrastructure. Fortunately, no major fatalities were reported, but the eruption had a profound impact on the local population, highlighting the vulnerability of the region to volcanic hazards.
Earlier Eruptions: 1930s and 1940s Activity
Lewotobi Volcano has a long history of eruptions, with significant events dating back to the early 20th century. In 1933, an ash eruption occurred on December 17, resulting in the ejection of incandescent material that was visible from surrounding areas such as Doeang and Nobo. Six years later, in 1939, another eruption took place on December 17, with explosive activity that caused stones to rain down in Hokeng Mission for approximately 10 minutes. These early eruptions were significant but did not cause widespread destruction or fatalities.
Another eruption occurred in 1932, when a gas explosion took place at Lewotobi on July 28. This event was smaller in scale compared to later eruptions, but it demonstrated the ongoing volcanic activity in the region.
Lewotobi and Its Role in the Pacific Ring of Fire
Lewotobi Volcano is part of Indonesia’s “Ring of Fire,” a region known for its high level of seismic and volcanic activity. The Ring of Fire is a horseshoe-shaped area around the Pacific Ocean where several tectonic plates meet, leading to frequent earthquakes and volcanic eruptions. Indonesia, being located along this active zone, is home to numerous volcanoes, many of which are closely monitored due to their potential for destructive eruptions.
Indonesia’s geological setting makes it one of the most volcanically active regions in the world. The eruption history of Lewotobi, along with other nearby volcanoes such as Mount Merapi and Mount Ibu, illustrates the ongoing risks faced by residents living near these active volcanoes. While many of these eruptions are explosive, the government and scientists continue to monitor volcanic activity closely in order to provide early warnings and minimize the impact of future eruptions.
Preparedness and Risk Mitigation Efforts
In light of Lewotobi’s volatile nature, the Indonesian government has implemented various measures to ensure the safety of the local population. These measures include the establishment of exclusion zones, early warning systems, and regular seismic monitoring. In addition to the scientific efforts, local authorities conduct public awareness campaigns to educate residents about evacuation plans and safety protocols in the event of an eruption.
Despite these efforts, the risks associated with Lewotobi Volcano and other active volcanoes in Indonesia remain significant. The unpredictable nature of volcanic eruptions, combined with the dense population in volcanic regions, means that communities must remain vigilant in the face of potential disasters.
Conclusion: The Future of Lewotobi Volcano
Lewotobi Volcano remains one of Indonesia’s most active and potentially dangerous volcanoes. Its explosive eruptions have had significant impacts on nearby communities, and the geological characteristics of the volcano suggest that future eruptions are likely. Given the unpredictable nature of volcanic activity at Lewotobi, ongoing monitoring and preparedness efforts are crucial for minimizing the impact of future eruptions.
As part of the Pacific Ring of Fire, Lewotobi serves as a reminder of the dynamic and hazardous nature of the region’s geological environment. By continuing to study and monitor the volcano, scientists hope to improve early warning systems and enhance public safety in the event of future eruptions.
The Nature of the Emergency: Mt. Lewotobi Laki-Laki Eruptions in Late 2023 and Early 2024
The eruption of Mt. Lewotobi Laki-Laki, located on Flores Island, Indonesia, has escalated into a significant natural disaster. Over the course of several days in late December 2023 and early January 2024, the volcano produced a series of explosive eruptions, with widespread implications for the surrounding communities. The eruption began on December 23, 2023, and continued intermittently until January 1, 2024, culminating in heightened seismic activity and the issuance of a disaster alert by the Indonesian government.
The first signs of volcanic activity were observed on December 23, 2023, when a large crack was detected in the northwest area of the peak, approximately 160 meters in length. This crack emitted thick, white smoke, which reached an altitude of around 300 meters above the summit. The volcanic activity intensified after this initial event, with the eruption reaching a new level of severity by January 1, 2024. At 00:03 Central Indonesian Time on January 1, the eruption escalated, with continuous seismic activity and volcanic tremors. Seismographs recorded significant earthquake activity with amplitudes reaching up to 7 mm, indicating a notable increase in volcanic pressure beneath the surface.
By this time, a new eruption center was observed to have formed in the southern-southeastern region of the summit. The eruption column reached altitudes of 1,000 to 1,500 meters above the peak, with a mix of white, grey, and black ash being emitted into the atmosphere. This eruption was accompanied by a large number of volcanic earthquakes, with more than 100 tremors recorded in the days following the initial eruption. Additionally, 79 tectonic earthquakes were reported, further underscoring the heightened seismic activity.
In response to the mounting volcanic activity, the Indonesian Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the status of Mt. Lewotobi Laki-Laki from Level II to Level III on January 1, 2024, signaling a high risk of explosive eruptions. The warning highlighted the potential danger posed by volcanic rocks and pyroclastic flows, which could extend up to 3 km from the summit. The warning also noted the risk of pyroclastic flows traveling up to 4 km to the northwest, north, and southeast of the volcano. As a result, an exclusion zone was established, and local authorities began to implement emergency measures to protect the surrounding population.
The Impact and Scale of the Emergency: A Moderate to High-Level Crisis
Geographical Affected Areas
Mt. Lewotobi is a twin volcano, situated in East Flores District in East Nusa Tenggara Province, Indonesia. The volcano has two main summits: Lewotobi Laki-Laki (1,584 meters in elevation) and Lewotobi Perempuan (1,703 meters in elevation), both of which are located on Flores Island at latitude -8.5539°S and longitude 122.7805°E. The twin volcanoes, which are situated in a seismically active region, are a significant geological feature of the area, contributing to the frequent volcanic eruptions that have shaped the surrounding landscape.
In the wake of the eruption, several villages in the surrounding districts were severely impacted. The five villages in Wulanggitang Sub-District that were affected by the eruption include Nawakote Village, which encompasses Duang Hamlet and Bawalatang Hamlet; Boru Village with Podor Hamlet; Hokeng Jaya Village; and Klatanlo Village. In addition, the eruption impacted Ile Bura Sub-District, particularly Dulipali Village and Nobo Village, both of which are in close proximity to the volcano and have been exposed to the ongoing volcanic ashfall. The fallout from the eruption has severely impacted these communities, especially in terms of air quality, infrastructure damage, and the health of residents.
The volcanic ash and gases that spewed from the volcano have also caused environmental and agricultural damage, affecting crops and soil quality, which is a major concern for the local economy. The villages located close to the volcano have seen their water sources contaminated, and the ashfall has disrupted daily life, with people forced to take shelter in evacuation camps.
Population Affected and Evacuations
The eruption of Mt. Lewotobi Laki-Laki has affected thousands of people in the region. As of January 4, 2024, 3,224 people have been evacuated from the affected villages and relocated to temporary shelters. The majority of these evacuees are now staying in shelters set up by the local government, as well as with relatives in nearby villages. The evacuation efforts have been extensive, with emergency response teams working to transport people to safer locations.
In addition to those who have been evacuated to shelters, another 644 people sought refuge in Konga Village, located in Titehena District, while 178 people were evacuated to Sikka District, far from the volcano’s immediate danger zone. The total number of evacuees has continued to rise as more people are displaced by the ongoing eruption, with reports suggesting that as many as 4,112 individuals have been affected by the eruption, with numbers likely to increase in the coming days.
Evacuation efforts have been further complicated by the fact that many people sought refuge in makeshift shelters, such as tents erected in community gardens or at relatives’ homes. These temporary shelters, while providing immediate relief, are not equipped to handle large numbers of displaced people, and health risks are increasing as the situation evolves.
Health Impact and Strain on Local Health Services
As the eruption has displaced thousands of people, the health implications of the disaster are becoming more apparent. In addition to the physical dangers posed by volcanic eruptions, such as lava flows, pyroclastic material, and falling rocks, the ongoing ashfall and volcanic gases have contributed to an increase in respiratory illnesses and other health complications among evacuees.
According to data from the Indonesian Ministry of Health (MoH), by January 4, 2024, a total of 898 people had reported minor injuries and required outpatient medical care. These injuries were largely a result of exposure to volcanic ash and debris, with people experiencing hypertension, headaches, coughs, fever, and respiratory infections. Children, pregnant women, and elderly individuals are particularly vulnerable to the health risks posed by the volcanic ash, and health centers in the affected regions have been overwhelmed by the increasing number of patients.
The Boru Sub-District Health Center has reported treating 726 patients, including 75 infants and toddlers, 2 pregnant women, 139 elderly individuals, and 2 people with disabilities. These groups are at greater risk for developing more serious health complications, and the local health facilities are struggling to keep up with the demand for medical services.
In response to the health emergency, the Indonesian government has mobilized medical teams, including health workers from local clinics, national disaster relief agencies, and humanitarian organizations. However, as the number of evacuees grows and health problems increase, the local health services may be stretched beyond their capacity, which could lead to further challenges in providing care.
Local and National Response Capacity: Coordinating Relief Efforts

These include the provision of clean drinking water, the establishment of temporary shelters, and the deployment of mobile health units to provide urgent medical care. Additionally, evacuation vehicles and transportation teams have been mobilized to ensure that vulnerable groups, including children, elderly, and pregnant women, are safely relocated to evacuation posts.
However, there are several logistical challenges in providing consistent relief to such a large number of displaced individuals. The accessibility of some affected areas remains difficult due to damaged infrastructure and ongoing seismic activity. As a result, the emergency response teams have had to rely on helicopters, boats, and other alternative transport methods to deliver essential supplies to the most isolated areas.
Key Needs and Gaps in Relief Efforts
As the situation continues to evolve, several critical needs have been identified, and gaps in relief efforts remain.
Food and Nutrition
The most immediate need for evacuees is food assistance. Not only do evacuees require ready-to-eat meals, but they also need access to food that can be prepared into balanced, nutritious meals in the emergency shelters. Additionally, the volcanic ash has posed a risk to food safety, as ash can contaminate crops and water sources. Proper management of public kitchens is necessary to ensure that food is prepared in safe conditions, far from the influence of the volcanic fallout.
Non-Food Items (NFIs)
Non-food items (NFIs), such as sleeping mats, blankets, and clothing, are urgently needed in the evacuation camps. These items are essential for maintaining basic living conditions in the camps and ensuring the health and well-being of the evacuees. Sanitary items, such as diapers, sanitary napkins, and eucalyptus oil, are also in high demand, especially for pregnant women, children, and older people.
Health and Medical Care
As the number of evacuees continues to grow, health services will become increasingly important. There is a pressing need for respiratory protection, including masks, to prevent respiratory infections caused by volcanic ash and dust. Local health services are currently active, but additional support will be necessary if the number of affected people continues to rise.
Psychosocial Support and Protection
Given the trauma associated with volcanic eruptions, there is a significant need for psychosocial support for survivors, especially for vulnerable groups such as children and the elderly. As the eruption continues to affect the daily lives of those displaced, mental health support and protection services are crucial in mitigating the long-term effects of the disaster.
Conclusion: Ongoing Challenges and Future Preparedness
The eruption of Mt. Lewotobi Laki-Laki in December 2023 and January 2024 has caused significant disruption to the lives of thousands of people in East Flores District. Despite the immediate and ongoing efforts of local, regional, and national authorities, the situation remains precarious, with more people at risk of being displaced and exposed to further hazards from volcanic activity.
The continued collaboration between government agencies, humanitarian organizations, and local communities will be critical in managing the crisis and ensuring that affected populations receive the aid and support they need. As the eruption continues and the impact on local infrastructure and livelihoods becomes more apparent, it is crucial to address both the immediate needs of the displaced population and the longer-term challenges of recovery and rebuilding.
Moving forward, lessons learned from this crisis should inform future disaster preparedness and response efforts in Indonesia, where volcanic eruptions remain an ever-present risk.
