Overview

Inielika is a broad, low volcano in central Flores Island that was constructed within the Lobobutu caldera. The complex summit contains ten craters, some of which are lake filled, in a 5 km2 area north of the city of Bajawa. The largest of these, Wolo Runu and Wolo Lega North, are 750 m wide.

A phreatic explosion in 1905 formed a new crater, and was the volcano's only eruption during the 20th century. Another eruption took place about a century later, in 2001. A chain of Pleistocene cinder cones, the Bajawa cinder cone complex, extends southward to Inierie.

    Regional Volcanic Activity
    The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

    About the Photo

    Two of the many summit craters of Inielika can be seen in the left foreground. It is a broad, low volcano in central Flores Island that was constructed within the Lobobutu caldera. The complex summit includes ten craters, some of which contain lakes. A phreatic explosion that formed a new crater in 1905 was the volcano's only eruption during the 20th century. Inierie volcano is the prominent peak on the right horizon.
