This folder contains the earthquake catalog that was built and analysed in:

Angélique Marck, Lars Ottemöller, Gökhan Aslan, Kundan Kumar, Odleiv Olesen and Stéphane Rondenay: Leakage during hydropower tunnel construction: A possible trigger mechanism for the earthquake swarm at Sørfjorden, Norway  [Submitted to The Seismic Record, 2025]

1. hypoDD_sorfjorden_catalogue_simplified.csv: This catalog contains event time, locations, along with magnitudes for the 1833 events. 

2. hypoDD.reloc: This catalog contains locations for 1833 events in the hypoDD.out format, as defined at: https://www.ldeo.columbia.edu/~felixw/papers/Waldhauser_OFR2001.pdf, (One event per line: Event ID, Latitude, Longitude, Depth, East-west location (m) relative to cluster centroid,  north-south location (m) relative to cluster centroid, depth location (m) relative to cluster centroid, East-west error (m), North-South error (m), depth error (m), Year, Month, Day, Hour, Minute, Second, Magnitude, Number of cross-correlated P wave data, Number of cross-correlated S wave data, Number of catalog P wave data, Number of catalog S wave data, Rms residual for cross-correlated data, Rms residual for catalog data, Cluster index). Note that EX, EY, EZ (location errors) are not meaningful here. 

The locations of stations (WGS84 datum) used to compile the dataset are provided in Station_location.txt. The columns in this file include the station name, latitude (°) and  longitude (°).
