Iliwerung

Iliwerung is a dormant volcano on Lembata Island with multiple craters and lava domes arranged in a north-south line, forming a peninsula that faces toward the south. The summit reaches approximately 1000 meters in elevation and displays clear signs of volcanic formation.

The volcano's summit dome was created during a major eruption in 1870, marking when documented volcanic activity began. Since then, further eruptions have shaped the landscape and the attention people pay to the mountain.

Local communities on Lembata Island have developed deep knowledge about how the volcano behaves, sharing observations and stories across generations. This understanding shapes daily life and the precautions people take as they live in its presence.

Visitors need permission from local authorities to access the volcano area, and hiring a guide familiar with the terrain is essential for safe navigation. The routes can be steep and challenging, so being in good physical condition makes the climb easier.

Beneath the ocean surface about one kilometer south of the coast lies a hydrothermal vent called Hobal that erupted in 1973-1974. During this eruption sequence, three temporary islands briefly emerged from the water before sinking back.
