Quaternary Geoscience

Unlocking Earth’s most recent geological past to address today’s environmental challenges

Who We Are

The Quaternary Geoscience Research Group at the Faculty of Mathematics and Natural Sciences, Universitas Indonesia (FMIPA UI), is a multidisciplinary research collective dedicated to studying Earth’s most recent geological period — the Quaternary — spanning the last ~2.6 million years to the present day.

Research Focus

Three Research Pillars

Geochemistry & Sedimentology

Mercury cycling in marine sediments, deep-sea Hg burial rates, volcanic Hg emissions, carbonate diagenesis, and trace metal proxies for past environments.

Geo-hazard & Engineering Geology

Landslide susceptibility mapping, tsunami hazard assessment, geological mapping, and engineering geology for disaster risk reduction in Java and beyond.

Science Education & Outreach

Community-based hazard education (CREDO program), Geoscience Open Day, Science Panel for Borneo, and development of open-access geoscience teaching resources.
