Seismic monitoring of mass movements in the Mont Blanc massif

# Data Repository Mass movements monitoring results - README ## Overview This repository contains dataset files and supporting resources. The data is provided in both plain and compressed formats. ## Files Included - MassMoveLoc_inputs.tar.gz A tar.gz archive with input files for running MassMoveLoc including: NonLinLoc velocity files for BackTrackBB, site amplifications for Amplitude Decay software, DEM file and station inventory. - reference_dataset.csv A csv file containing reference events with associated seismic events. | Field | Description | |---|---| | `name` | Name of the event containing date and location. | | `id` | Unique identifier of the mass movement field observation. | | `volume` | Volume estimation (from field observation). | | `lat` | Latitude of the event location in decimal degrees (from field observation). | | `lon` | Longitude of the event location in decimal degrees (from field observation). | | `elevation` | Elevation of the event location above sea level (in meters). | | `event-id-s` | SeisComP event identifier assigned to the seismic event. | | `time-s` | Event origin time calculated by SeisComP. | | `lat-s` | Event latitude calculated by SeisComP (decimal degrees). | | `lon-s` | Event longitude calculated by SeisComP (decimal degrees). | | `rms-s` | Root Mean Square (RMS) of travel-time residuals from the SeisComP location solution. Indicates the quality of the location fit; lower values indicate a better solution. | | `gap-s` | Maximum azimuthal gap between seismic stations used in the SeisComP solution (degrees). Smaller gaps indicate better station coverage. | | `erh-s` | Estimated horizontal location error from SeisComP. | | `picks-s` | Number of seismic phase picks used by SeisComP for event location. | | `sta-s` | Number of seismic stations contributing data to the SeisComP event solution. | | `mag-s` | Magnitude calculated in SeisComP. | | `distance-sc` | Distance between the reference location and the SeisComP calculated location. Units depend on the dataset definition (typically meters or kilometers). | | `time-accuracy` | Temporal uncertainty of the event observation time. | | `Type` | Event classification. Possible values: `ice` (serac fall) or `rock` (rockfall). | - mass_movements_2011_2025.csv A CSV file containing catalog data for 2011-2025. | Field | Description | |-----------|-------------| | `ID` | Unique identifier assigned to each event. | | `time` | Timestamp indicating the time of event detection or occurrence. | | `latitude` | Reference geographic latitude of the event location (manual picking based location). | | `longitude` | Reference geographic longitude of the event location (manual picking based location). | | `magnitude` | Estimated magnitude of the event. | | `latitude_amp_dec` | Latitude estimated using the amplitude decay localization method. | | `longitude_amp_dec` | Longitude estimated using the amplitude decay localization method. | | `lat_automatic` | Latitude estimated using the combined automatic localization algorithm. | | `lon_automatic` | Longitude estimated using the combined automatic localization algorithm. | | `max_azimuthal_gap` | Maximum azimuthal gap between observing stations used for localization, expressed in degrees. Lower values indicate better station coverage and more reliable location estimates. | | `mean_energy` | Geometrical mean of seismic pseudo-energy. | | `std_energy` | Standard deviation of the estimated event energy. | | `mean_duration` | Mean duration of the recorded event signal. | | `std_duration` | Standard deviation of the event duration. | | `mass_log` | Logarithm of the estimated event mass. | | `radius_01` | Location precision of the combined automatic approach (radius of a circle containing 10% of the grid energy). | | `stations_used_for_size_estimation` | Number of stations used for estimating event size-related parameters. | | `mass_log_std` | Standard error of the logarithmic mass estimate, representing the uncertainty of the mass calculation at the 95% confidence level. | - mm_results.part_aa, mm_results.part_ab, mm_results.part_ac, mm_results.part_ad, mm_results.part_ae Archive files containing all resulting and input files for running MassMoveLoc on all detections from 2011-2025. These files are parts of a larger split archive. They must be combined before extraction. - article_repository_volume_estimation.zip A ZIP archive containing all files necessary for creating a model for estimating size of mass movements. ## How to Extract the Data ### 1. Reconstruct the Split Archive The `mm_results.part_*` files were split using a tool `split`. To reconstruct the original file, run: ```bash cat mm_results.part_* > mm_results.tar.gz ``` ### 2. Extract the Reconstructed Archive If the result is a .tar.gz file: ```bash tar -xzvf mm_results.tar.gz ``` ### 3. Extract the ZIP Archive ```bash unzip size_estimation.zip ```
