At the top of this mountain has a large crater resembling a crescent-shaped caldera called a resident with the name ‘Metong Lamataro’. It is part of the old crater of Mount Lewotolo. A cone was formed in the southeastern part of ‘Metong Lamataro’ as the highest peak of the current Lewotolo Mountain. The cone has an active crater pit at its peak with a solfatara smoke blow in almost all cones. Solfatara is light yellow, sulphurous brimstone is found in east, north and south of this new cone…

History of eruption;
  • 1660; There was an eruption on the central crater (Neumann van Padang, 1951, p.208). The eruption data is contained in ‘Wouter Schout’s Reistogt naar en door Oostindien 1775’ (v.1, p 78, 80).
  • 1819; There was a normal eruption on the central crater (Nuemann van Padang, 1951, p. 201).
  • 1849; On October 6 there was an eruption in the central crater. Description of the eruption is found in Prospectus van Natuurkundig Tijdscrift voor Nederlandsch Indie (1851, p.154).
  • 1852; On 5 and 6 October eruptions erupted in the central crater destroying the surrounding area (Neumann van Padang, 1951, p. 201). According to local residents has appeared K2 crater and solfatara complex on the eastern slope.
  • 1864; Central crater eruption.
  • 1889; There was a normal eruption on the central crater according to Neumann van Padang (1951, p. 201), while Verbeek described the steaming smoke pole in mt. Ili Lewotolo.
  • 1920; Reksowirogo (1972, p.8) and Neumann van Padang (1951) wrote that perhaps according to locals there had been a small eruption. At that time there was an exploratory funnel.
  • 1939; On January 6th, February 3rd, and June there was an increase in volcanic activity.
  • 1951; December 15, an increase in volcanic activity.

Topology & Geology;
According to Hartmann (1935, p 820-821), all the enterprising volcanoes of Lomblen are marked by a fault line at the summit. The mountain route runs southeast-southwest. Mount Ili Lewotolok has a beautiful and orderly cross-section, but in some places there is an irregularity caused by the lava flow that ends in the mountain wing. The slopes of Mount Ili Lewotolok consist of volcanic ash, breccia, volcanic sand, volcanic bombs, and lava flows, except on relatively rare southwestern slopes.
Neumann van Padang (1951, p. 201) writes that this volcano is located in the northern part of the Lomblen Island Peninsula. This is a real cone, when viewed from the north or east. Its composition consists of volcanic ash, volcanic breccia, and lava flows, many of which come to shore.
Hartmann (1935, p.817-824) divides the three phases of its formation:

  1. The original volcano with a crater diameter of 1300 m (K0).
  2. A hole raised 9 m from an original hole and conical complex with a K1 crater, in a large crater K0.
  3. The current original topography and the K2 crater, east of the so-called former. At this time K1 crater measuring 900 x 800 m, the height between 1275-1150 m above sea level, K2 crater measuring 250 x 200 m berketinggian 1319-1225 m above sea level and essentially 130 x 100 m berketinggian 1214 m above sea level.

Reksowirogo (1972, p.4) writes that Mount Ili Lewotolok built on limestone coral and has a height of 1319 m above sea level located on the northern peninsula of Lomblen Island, East Flores regency. At the top of Mount Ili Lewotolok there is a large crater with a size of 800 x 900 m, in the southwest there are cones with a height point 1319 m above sea level. Near the new cone there is a crater with a solfatara blast that almost surrounds the new cone, mostly in the western lerang while in the east a bit.
Its topography when compared to what is listed in the topographic map of 1960 peak is almost no change. Notable changes are only the extent or spread of solfatara on the eastern slopes of the highest point (new cone). In the ambulance of the lava flow that is in Group II and III as well as in Group IV. But the spread of fumarola on the upper edge of the southwest and in the K1 crater is reduced (Group IX).
Avalanches from the deep slopes of the west, north-east and east of the large crater occur, so many bundles are buried in the bottom of the crater. New material in the form of volcanic bombs was not found. Solfatara is light yellow, sulphurous brimstone is found in east, north and south of this new cone.
