Volcano eruption in indonesia-Mount Lewotobi Laki-Laki in East Flores Regency, East Nusa Tenggara Province, erupted again early Wednesday (9/7/2025) at 2:52 a.m. WITA. As of this report, the volcano remains at Level IV (Awas)—the highest alert level in Indonesia’s volcano monitoring system—signaling that the eruption has not yet stopped.
The latest eruption marks the 56th eruption within the past week, a clear indication that volcanic activity is still ongoing and intense in the Mount Lewotobi Laki-Laki.
According to Indonesia's Center for Volcanology and Geological Hazard Mitigation (PVMBG), as reported on the MAGMA Indonesia platform, the height of the ash column could not be visually confirmed due to poor visibility. However, seismic activity recorded on the 9th of July confirms that the mountain remains highly active.
The Mount Lewotobi Laki-Laki eruption was first recorded on the 17th of June, with the massive and significant eruption occurring. It continued to the next day, on 18th June, when the officials raised the alert level to its maximum level, Level IV (Awas).
Most recently, on 7th July, Mount Lewotobi Laki-Laki eruption released ash clouds up to 18 kilometers into the sky, blanketing nearby villages with gravel and volcanic ash. Two additional eruptions occurred early on July 8, with ash plumes reaching 4,000 meters, disrupting daily life and public services.
Today, 9th July, Mount Lewotobi Laki-Laki continues to show its intense volcanic activity. Seismic monitoring recorded three eruption quakes with amplitudes ranging from 11 to 29.6 mm, along with two gas emission quakes, one low-frequency quake, one deep volcanic quake, and three distant tectonic quakes. These continued volcanic and seismic activities clearly show that the eruption is ongoing, and the volcano remains unstable.
Regarding this volcanic situation, residents within a 6 km radius and a 7 km sectoral radius on the southwest–northeast side of the crater have been strongly advised to evacuate immediately for their safety.
Volcano Eruption in indonesia: Impact on Flights
The ongoing Mount Lewotobi Laki-Laki eruption has significantly disrupted air travel in the region, including routes to and from Bali as one of Indonesia’s most popular tourist destinations. While Ngurah Rai International Airport in Bali remains operational since the report said that the volcanic ash had not affected the airspace, flights to Australia, Singapore, South Korea, and Labuan Bajo are among those impacted with flight cancellations and delays.
In addition, many airlines have experienced flight delays and cancellations due to drifting volcanic ash, such as Jetstar, Virgin Australia, and AirAsia Indonesia. Several airports in the Nusa Tenggara region, including Maumere, Ende, Larantuka, and Kupang, have experienced full closures due to safety concerns.
Given this situation, travelers with upcoming trips to or from Bali, Lombok, or Flores are strongly advised to check with their airlines for the latest status updates. The presence of volcanic ash in flight paths poses a risk to aircraft engines and visibility, which is why precautionary measures, by delaying and cancelling flights, are being taken.
Moreover, American and other countries’ authorities have advised and warned their citizen. They recommended avoiding any travel to or from Nusa Tenggara Province and staying updated through official airline websites.
Indonesian authorities continue to monitor the situation closely and keep updating the situation regarding the Mount Lewotobi Laki-Laki eruption. They are urging people— especially those who are living near Mount Lewotobi Laki-Laki—to remain alert.
