This is the experimental data used in manuscript: "Rock anisotropy promotes hydraulic fracture containment at depth". This data set has 5 folders: K1, T2, M3 and M4 contain the raw data collected by active acoustic monitoring system and various pumps and transducers. <br> The readings of the Top Industrie syringe pump (for fluid injection), pressure transducers at downstream, and GDS pumps that provide confining stresses along all three directions via flatjacks are provided by two excel spreadsheets - Low_frequency_measurements.csv and Pump_reading.csv.<br> For active acoustic data, there are four different files named by the starting time for each experiment. The .json file contains the basic information of each experiment. The .txt file contains the acquisition time for each active acoustic sequence. The .bin file contains the collected waveforms of all acoustic sequences. Processed_data includes the synchronized pressure data (Pressure_data.xlsx) and detailed acoustic emission results (AE_K1.csv, AE_T2.csv, AE_M3.csv, AE_M4.csv).<br>
