Mount Ile Lewotolok, located in Lembata Regency, East Nusa Tenggara, is currently showing a significant increase in volcanic activity. According to a report from the Ile Lewotolok Volcano Observatory (PGA), this escalation is evidenced by the rising intensity of eruptions and powerful booming sounds heard from mid-June to early July 2026.
Ile Lewotolok PGA officer Stanislaus Arakian revealed that despite the surge in seismic activity, the volcano's status remains set at Level II (Alert). The booming sounds have even been reported to rattle the walls and window panes of homes of residents living near the foot of the mountain.
Monitoring data shows high numbers across various types of earthquakes. Throughout June 2026, a total of 1,746 eruption earthquakes and 2,198 gust earthquakes were recorded. This upward trend continued into the first week of July, with seismic intensity remaining fairly active compared to the previous period.
In addition to seismic threats, visual observations revealed an eruption column reaching heights of up to 600 meters above the peak. Incandescent material ejecta was also detected spreading between 100 and 500 meters in several directions, including the mountain's southeastern and southern sectors.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has issued strict instructions for the public, hikers, and tourists to avoid the exclusion zone within a two-kilometer radius of the eruption center. Residents are also advised not to panic regarding the booming sounds and are encouraged to wear masks and eye protection to guard against potential volcanic ash exposure.
