 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 slippan> 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').
