Data accompanying the paper entitled "Fault weakening during short seismic slip pulse experiments: The role of pressurized water and 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, "Data submitted to 4TU.Researchdata" is the compressed file ('.rar'), which consists of 1) a table listing the information of all the experiments, 2) 82 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. The dataset "RawData submitted to 4TU.Researchdata" contains the raw data of the 82 data files ('.csv').

荷兰格罗宁根气田自20世纪90年代起便出现人工诱发地震活动，其中最强震例发生于2012年，震级为MW 3.6。尽管已有多项近期研究，但针对此类小震级（即震级3~4级）地震过程中的断层滑移机制，目前仍不明确。本研究采用全新设计的实验装置开展实验室模拟实验，以复现小震级人工诱发地震典型的脉冲式（即短暂快速）断层滑移行为；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下，对断层滑移行为进行监测。本随附数据集"Data submitted to 4TU.Researchdata"为RAR格式压缩文件（'.rar'），包含三部分内容：1） 汇总所有实验基本信息的表格；2） 82个经平滑处理的实验数据文本文件（'.txt'），每个文件内的数据为每约66个原始数据点采样一次的平滑结果；需注意，单个实验可能对应2~5个数据文件（即记录片段）；3） 198张展示初步研究结果的EMF格式图表（'.emf'），每张图表的标题与对应数据文件的名称一致。另一数据集"RawData submitted to 4TU.Researchdata"则包含上述82个数据文件对应的原始数据，格式为CSV文件（'.csv'）。
