Map showing the segmentation of the Sumatra Fault Zone (SFZ) and historical earthquakes. The SFZ has generated many historical earthquakes with magnitude ≥7 (Sieh and Natawidjaja, 2000)

Map of the "Ring of Fire" showing volcanoes, seismicity and plate boundaries around the Pacific Ocean.

Our multi-disciplinary project explores the paleotsunami record in northwestern Aceh Province, Sumatra.

Studies focused on tectonic activity along the Sumatran Fault zone (SFZ), which traverses the entire 1900-km length of Sumatra, are still lacking. The SFZ is segmented and the slip rate varies for each segment, but rates are poorly known, particularly at the southern end of the SFZ.

SuGAr has been observing surface deformation in Sumatra since 2002.

Gede and Salak, high-risk volcanoes in West Java, are representative of many arc volcanoes.

This map of Southeast Asia shows the volcanoes with historical eruptions (less than 10 000 years old).
