This dataset contains annotated micro-seismic recordings and images acquired in the context of project X-Sense2 (financed by nano-tera.ch, ref. no. 530659) at the Matterhorn Hörnligrat fieldsite on 3500 m a.s.l.. Additionally, secondary data is provided which can used for further analysis. This dataset comprises a selection of measurements. The data folder contains two datasets and additional data (secondary data). Please refer to the following publication for further information: Meyer, M., Weber, S., Beutel, J., Thiele, L.: Systematic Identification of External Influences in Multi-Year Micro-Seismic Recordings Using Convolutional Neural Networks, Earth Surface Dynamics, in review, 2018. dataset The dataset/ folder contains micro-seismic data, images, and annotations. A list of every datapoint including annotations and start/end time is provided in two csv files in the annotations/ folder. event_dataset The event_dataset/ folder contains micro-seismic data and annotations. A list of every datapoint including annotations and start/end time is provided in two csv files in the annotations/ folder. For a selected time period bounding boxes are provided in the bounding_box.csv file. Micro-seismic data The data was recorded using a Nanometrics Centaur digital recorder and Lennartz electronic low-noise seismometer LE-3Dlite MKIII (1−100 Hz). The Nanometrics Centaur digital recorder aquires data with 24-bit resolution with a sampling rate of 1000 sps. The data is stored in .miniseed-format. Image data Images where acquired with a remote controlled high-resolution camera (Nikon D300, 24 mm fixed focus). Annotations The data was annotated manually by the authors. Secondary data The secondary data comprises data from different sensors, including wind speed, rock temperature and radiation. Additionally, weekly aggregated hut occupancy of the Hörnlihut from the years 2016/2017 and event timestamps from running a STA/LTA trigger on an internal version of the micro-seismic data are provided.
