Ebulobo (also called Amburombu or Keo Peak), is a symmetrical stratovolcano in central Flores Island. It has a flat summit lava dome and contains a 250 m summit crater, breached on 3 sides. In 1830, a lava flow (known as Watu Keli lava flow) descended from the northern breach on the summit and reached 4 km length.
A small summit eruption occurred on 28th February 1969, where "fire", steam and ash were reported.

Remark:

Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
