The Southwestern Adriatic Margin (SAM) shows evidence of widespread failure events that generated slide scars up to 10 km wide and extensive slide deposits with run out distances greater than 50 km. Chirp-sonar profiles, side-scan sonar mosaics, multibeam bathymetry and sediment cores document that the entire slope area underwent repeated failures along a stretch of 150 km and that masstranspor...

Abstract Four previously unrecognized neotectonic fault scarps in southwest Namibia are described. These relatively straight, simple but segmented structures 16–80 km long and have measured vertical separations of 0.7–10.2 m. We estimate that each is capable producing earthquakes M w 6.4 or greater, indicating large may occur despite limited cumulative displacement. There strong evidence some t...

Abstract. Probabilistic seismic hazard assessment (PSHA), despite its deep criticism, is still the most common tool used to decide on acceptable risk and corresponding mitigation measures. We propose two consistency tests address variability of earthquake generation models found in PSHA studies: (i) one rule-of-thumb test where moment release from model converted an average slip a typical fault...

The Willandra Lakes complex is one of the few locations in semi-arid Australia to preserve both paleoenvironmental and Paleolithic archeological archives at high resolution. The stratigraphy of transverse lunette dunes on the lakes' downwind margins record a late Quaternary sequence of wetting and drying. Within the Willandra system, the Lake Mungo lunette is best known for its preservation of ...

Faults on microcontinents record the dynamic evolution of plate boundaries. However, most are submarine and difficult to study. Here, we show that southern part Isla Ángel de la Guarda (IAG) microcontinent, in northern Gulf California rift, is densely faulted by a late Quaternary-active normal fault zone. To characterize onshore kinematics this Almeja zone, integrated remote mapping using high-...
