Proceedings of the 12th International INQUA meeting on paleoseismology, active tectonic and archaeoseismology

no modern geochronology has been applied to quantitatively constrain slip rates for any faults in this area. The fault is significant due to its proximity to infrastructure, running within 3 km of the Jindabyne Dam wall, a key component of the Snowy Mountains Hydro-electric Scheme. The town of Jindabyne, with a permanent population of 5000, is also a major and expanding tourist destination, whose population swells to more than 20,000 during the ski season. The Hill Top Fault The Hill Top Fault has recently been identified through interpretation of a LiDAR DEM (Figure 3, Figure 5). The fault strikes in a roughly N-S direction and is located in the block uplifted between the Jindabyne Thrust and Barneys Range Fault (Figure 3). The Hill Top Fault terminates against the Jindabyne Thrust at its southern end (also ~ 3 km from the Jindabyne Dam), while at its northern end it deviates to the west to apparently merge with the Berridale Wrench Fault.
