Holocene acceleration of deformation and postseismic relaxation are two hypotheses to explain the present-day deformation in the Central Nevada Seismic Belt (CNSB). Discriminating between these two mechanisms is critical for understanding the dynamics and seismic potential of the Basin and Range province. Interferometric synthetic aperture radar detected a broad area of uplift (2 to 3 millimeters per year) that can be explained by postseismic mantle relaxation after a sequence of large crustal earthquakes from 1915 to 1954. The results lead to a broad agreement between geologic and geodetic strain indicators and support a model of a rigid Basin and Range between the CNSB and the Wasatch fault.
全新世变形加速和震后松弛是解释内华达中部地震带（CNSB）现今变形的两种假说。区分这两种机制对于理解盆岭省的动力学和地震潜力至关重要。干涉合成孔径雷达探测到一个广泛的隆升区域（每年2至3毫米），这可以用1915年至1954年一系列大型地壳地震后的震后地幔松弛来解释。这些结果使得地质和大地测量应变指标之间达成了广泛共识，并支持了CNSB和瓦萨奇断层之间存在刚性盆岭的模型。
