Indonesia’s Kelimutu volcano hosts three crater lakes that dramatically shift colors due to varying volcanic gases and mineral compositions. Depending on changes in acidity, sediment content, and iron levels, these lakes can appear red, turquoise, white, or black. Researchers now use satellite data to track these shifts, offering potential early warning signs for eruptions and broader insights into environmental change.
