Overview

Ebulobo, also referred to as Amburombu or Keo Peak, is a steep-sided symmetrical stratovolcano in central Flores Island. The Watu Keli lava flow traveled down the N flank to 4 km from the summit in 1830, the first of only four recorded historical eruptions of the volcano.

Volcanic Hazards & Risk Assessment

Primary Hazards

  • Pyroclastic flows

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

Ebulobo above the village of Boa Wae, located below the NW flank of the volcano. Ebulobo is located in central Flores Island and has a summit lava dome. Historical eruptions, recorded since 1830, include lava emission down the N flank and explosive eruptions from the summit crater.
