The major goal of this research proposal is to improve the imaging and interpretation of geological faults and fault systems using reflection seismic data, which makes images of the subsurface. I have a unique opportunity to analyse and interpret high-quality 2D seismic data that was recorded across geological faults that slipped during earthquakes near Christchurch, New Zealand, in September, 2010 and in February, 2011. Rather than a single fault trace, faults that ruptured the ground surface during the September earthquake have an en-echelon pattern with step-overs from one fault segment to the next. This research will yield significant new information about how displacement is transferred between fault segments.

这项研究建议的主要目标是利用反射地震数据改善地质断层和断层系统的成像和解释，从而形成地下图像。 我有一个独特的机会来分析和解释高质量的2D地震数据，这些数据是在2010年9月和2011年2月新西兰基督城附近地震期间在地质断层上记录的。 在9月地震中，地表破裂的断层不是单一的断层痕迹，而是从一个断层段到下一个断层段的阶梯状模式。 这项研究将产生重要的新信息，位移是如何在断层段之间转移。
