The PVMBG volcano observatory reported that a seismic activity increased at the volcano during the first half of December.
Between 1 and 17 December, the seismic station detected about 130 volcano-tectonic earthquakes.
Based on the monitoring, the alert level for the volcano is being raised to Level 2 (Alert).
People are advised to avoid an area of about 2 km from main craters.
Lewotobi volcano at the eastern end of Flores Island is one of the most frequently active volcanoes in the region. It has two peaks arranged on a NW-SE line separated by 2 km and a 1232 m high saddle. This gave the twin volcano its name Lewotobi „husband and wife“ (also spelled Lewetobi).
The two peaks correspond to the Lewotobi Lakilaki and Lewotobi Perempuan stratovolcanoes. Lewotobi Lakilaki (1584 m) has a summit crater of 400 m diameter open to the north. Lewotobi Perampuan (1703 m)’s crater is 700 m wide.
