Bagging It!

This volcano is one of Lembata’s main southern peninsulas and is comprised of several peaks with different names. The caldera itself is is known as the Lerek caldera and Ili Werung (or Iliwerung) has a lava dome which is thought to have been growing since 1870.

Ili Werung itself is only around 596 metres high according to the Bakosurtanal map of the area. The highest peak in this area is the much higher mountain located around 2 kilometres to the north-west (and much more accessible from local villages). Some sources state ‘Lama Heru’ is the name of the highest peak, whereas Bakosurtanal suggests Ile Mauraja as the name and 1,080m for the height. Some research is needed in consultation with local people and with a GPS device!

Another name is used for this range – Adowajo. This appears to refer to the range as a whole. The last major eruption was in 1999 but it would appear the much higher peak to the north-west (Lama Heru? Ile Mauraja?) is not (or no longer) active and it is only the much lower Ili Werung that is active.

Craters and lava domes have formed along N-S and NW-SE lines on the complex volcano; during historical time vents from the summit to the submarine SE flank have been active. The Iliwerung summit lava dome was formed during an eruption in 1870. In 1948 Iligripe lava dome grew on the eastern flank at 120 m altitude. Beginning in 1973-74, when three ephemeral islands were formed, submarine eruptions began on the lower SE flank at a vent named Hobal; several other eruptions took place from this vent before the end of the century.” (Smithsonian).
