Data accompanying the paper entitled "Fault weakening during short seismic slip pulse experiments: Implications for induced earthquakes in the Groningen gas field"

In the Groningen gas field of the Netherlands, induced seismic events have occurred since the 1990s. The strongest event occurred in 2012 with a magnitude of MW 3.6. How faults slip during such small magnitude earthquakes (i.e., magnitude 3 – 4) is not clear, despite several recent studies. We conduct laboratory experiments to simulate the pulse-like (i.e. short but rapid) fault slip behavior characteristic for small magnitude human-induced seismicity, using a newly designed experimental set-up enabling monitoring of the slip behavior under stress and displacement closer to conditions relevant to faults in Groningen. The enclosed dataset is the compressed file ('.rar'), which consists of 1) a table listing the information of all the experiments, 2) 84 data files ('.txt') of the smoothed data (~every 66 datapoints) for all the experiments. Note that one single experiment may contain 2-5 files (i.e. segments of records), and 3) 198 graphs showing the preliminary results ('.emf'). The title of the individual graphs correspond to the names of the data files.

荷兰格罗宁根（Groningen）气田自20世纪90年代以来便发生人工诱发地震事件，其中最强的一次发生于2012年，震级达MW 3.6。尽管近期已有多项相关研究，但针对震级3~4级的此类小震级地震中，断层的滑移机制仍未明确。本研究采用全新设计的实验装置开展实验室实验，以复现人类诱发小震级地震所特有的脉冲式（即短促且快速）断层滑移特征，该装置可在更贴近格罗宁根气田断层实际应力与位移条件的环境下，监测断层滑移行为。本随附数据集为格式为'.rar'的压缩文件，包含三部分内容：1）一张汇总所有实验基本信息的数据表；2）84个经平滑处理的实验数据文件（格式为'.txt'，采样间隔约为每66个数据点一次）；3）198张展示初步研究结果的图表（格式为'.emf'）。需注意，单个实验可能包含2~5个数据文件（即记录分段），且每张独立图表的标题与对应数据文件的名称一致。
