One of the most significant parameters for seismic hazard assessment analyses is the fault slip rate. The combination of both geological (long-term) and geodetic (short-term) data offers a more complete characterization of the seismic potential of active faults. Moreover, geodetic data are also a helpful tool for the analysis of geodynamic processes. In this work, we present the results of a local GPS network from the Baza sub-Basin (SE Spain). This network, which includes six sites, was established in 2008 and has been observed for seven years. For the first time, we obtain short-term slip rates for the two active faults in this area. For the normal Baza Fault, we estimate slip rates ranging between 0.3 ± 0.3 mm/yr and 1.3 ± 0.4 mm/yr. For the strike-slip Galera Fault, we quantify the slip rate as 0.5 ± 0.3 mm/yr. Our GPS study shows a discrepancy for the Baza Fault between the short-term slip rates and previously reported long-term rates. This discrepancy indicates that the fault could be presently in a period with a displacement rate higher than the mean of the magnitude 6 seismic cycle. Moreover, the velocity vectors that we obtained also show the regional tectonic significance of the Baza Fault, as this structure accommodates one-third of the regional extension of the Central Betic Cordillera.

Our GPS-related slip rates form the basis for future seismic hazard analysis in this area. Our results have further implications, as they indicate that the Baza and Galera Faults are kinematically coherent and they divide the Baza sub-Basin into two tectonic blocks. This points to a likely physical link between the Baza and Galera Faults; hence, a potential complex rupture involving both faults should be considered in future seismic hazard assessment studies.

断层滑动率是地震危险性评估分析中最重要的参数之一。地质（长期）数据和大地测量（短期）数据的结合提供了活动断层地震潜力的更完整特征。此外，大地测量数据也是分析地球动力学过程的有用工具。在这项工作中，我们展示了来自Baza子盆地（西班牙东南部）的本地GPS网络的结果。这个网络包括六个站点，成立于2008年，已经观察了七年。我们首次获得了该区域两个活动断层的短期滑动率。对于正常的Baza断层，我们估计滑移速率介于0.3±0.3 mm / yr和1.3±0.4 mm / yr之间。对于加拉拉断层走滑，我们将滑移率量化为0.5±0.3 mm / yr。我们的GPS研究表明，短期滑坡率与先前报告的长期滑坡率之间存在Baza断层差异。这种差异表明该断层目前可能处于位移速率高于6级地震周期平均值的时期内。此外，我们获得的速度矢量还显示了Baza断层的区域构造意义，因为该结构容纳了中部Betic Cordillera区域扩展的三分之一。

我们与GPS相关的滑移率构成了该地区未来地震危险性分析的基础。我们的结果具有进一步的意义，因为它们表明Baza断层和Galera断层在运动学上是连贯的，并且将Baza次盆地划分为两个构造块。这表明巴扎断层和加莱拉断层之间可能存在物理联系。因此，在未来的地震危险性评估研究中应考虑到可能涉及两个断层的复杂破裂。
