“…AudleyCharles et al 1979). Seismic reflection sections from around the arc, from Timor to Seram, have imaged foreland-directed thrusts surfacing in the peripheral troughs (Schlüter & Fritsch 1985;Jongsma et al 1989;Hughes et al 1996). Folding occurs but is relatively minor.…”

“…Attempts to image the geometry of the arc-continent collision have led to several geophysical investigations (e.g. Breen et al, 1989;Jongsma et al, 1989;Karig et al, 1987;Masson et al, 1991;McBride and Karig, 1987;Snyder et al, 1996). Shallow seismic data was first interpreted to show Kisar as an uplifted block between strike-slip faults (Jongsma et al, 1989).…”

Shallow seismic data was first interpreted to show Kisar as an uplifted block between strike-slip faults (Jongsma et al, 1989). Later, the British Institutions Reflection Profiling Syndicate (BIRPS) deep seismic reflection profile ''Timor'' imaged thrust faults and related folds along strike of Kisar (Snyder et al, 1996).…”

a b s t r a c tCoral terrace surveys and U-series ages of coral yield a surface uplift rate of $0.5 m/ka for Kisar Island, which is an emergent island in the hinterland of the active Banda arc-continent collision. Based on this rate, Kisar first emerged from the ocean as recently as $450 ka. These uplifted terraces are gently warped in a pattern of east-west striking folds. These folds are strike parallel to more developed thrust-related folds of similar wavelength imaged by a seismic reflection profile just offshore. This deformation shows that the emergence of Kisar is influenced by forearc closure along the south-dipping Kisar Thrust. However, the pinnacle shape of Kisar and the protrusion of its metamorphic rocks through the forearc basin sediments also suggest a component of extrusion along shear zones or active doming.Coral encrusts the island coast in many locations over 100 m above sea level. Terrace morphology and coral ages are best explained by recognizing major surfaces as mostly growth terraces and minor terraces as mostly erosional into older terraces. All reliable and referable coral U-series ages determined by MC-ICP-MS correlate with marine isotope stage (MIS) 5e (118-128 ka). The only unaltered coral samples are found below 6 m elevation; however an unaltered Tridacna (giant clam) shell in growth position at 95 m elevation yields a U-series age of 195 ± 31 ka, which corresponds to MIS 7. This age agrees with the bestfit uplift model for the island. Loose deposits of unaltered coral fragments found at elevations between 8 and 20 m yield U-series ages of <100 years and may represent paleotsunami deposits from previously undocumented tectonic activity in the region.

Abstract. The Indonesian archipelago is known for the occurrence of catastrophic earthquake-generated tsunamis along the Sunda Arc. The tsunami hazard associated with submarine landslides however has not been fully addressed. In this paper, we compile the known tsunamigenic events where landslide involvement is certain and summarize the properties of published landslides that were identified with geophysical methods. We depict novel mass movements, found in newly available bathymetry, and determine their key parameters. Using numerical modeling, we compute possible tsunami scenarios. Furthermore, we propose a way of identifying landslide tsunamis using an array of few buoys with bottom pressure units.
