Mt. Lewotobi Eruption Disrupts Flights, More Activity Possible

The Mt. Lewotobi Eruption on Friday, August 2nd, followed by continued activity on Saturday morning, caused significant disruption in East Nusa Tenggara and nearby areas. Thick volcanic ash and smoke forced the cancellation of flights and triggered alerts from Indonesia’s volcanology agencies. Authorities now warn of the potential for another eruption in the coming days.

Air Travel Affected Across Multiple Regions

Ash clouds from the eruption reduced visibility and created dangerous flying conditions. Kupang’s El Tari Airport suspended operations on Friday, halting flights to and from cities including Maumere, Bajawa, and Labuan Bajo. Several carriers grounded their aircraft due to safety concerns. On Saturday morning, further delays and cancellations were reported.

Ngurah Rai International Airport in Bali also experienced indirect impacts. Although not directly under the ash plume, flights connecting Bali to eastern Indonesia—such as those to Ende and Waingapu—were delayed or suspended.

Aviation authorities monitored the situation through satellite imagery and ash cloud modeling. The ash plume from Mt. Lewotobi reached a height of around 800 meters above the peak, with winds carrying particles westward. Pilots received alerts through NOTAMs (Notice to Airmen), and airlines adjusted flight paths accordingly.

Mt. Lewotobi Eruption: Risk of Renewed Activity

The Center for Volcanology and Geological Hazard Mitigation (PVMBG) continues to observe high levels of seismic activity beneath Mt. Lewotobi. Volcanologists noted multiple volcanic tremors and shallow earthquakes following Friday’s eruption. These indicators point to the movement of magma toward the surface.

The alert status remains at Level III (Siaga). People living within a 3-kilometer radius of the crater have been advised to evacuate and avoid any activity in the danger zone. Local disaster management teams have set up evacuation shelters and supply stations in nearby villages.

Officials also warned that the volcano could erupt again with little or no warning. Residents and travelers are advised to stay updated through official government channels and follow instructions from emergency services.
The Mt. Lewotobi Eruption has prompted a multi-agency response, combining efforts from meteorological, geological, and aviation authorities to reduce risks and protect communities.
