horus

Format

Original file format:

Year:: Origin Time (OT) year
Mo:: OT month
Da:: OT day
Ho:: OT hour
Mi: OT minute
Se: OT seconds and fractions
Lat: epicenter N latitude (in degrees)
Lon: epicenter E longitude (in degrees)
Depth: hypocenter depth (in km)
Mw: true or proxy moment magnitude
sigMw: moment magnitude uncertainty
Geo.Ita: "*" indicates that the epicenter is within the Italian mainland territory, otherwise " "
Geo.CPTI15: "*" indicates that the epicenter is within the spatial window of the CPTI15 catalog (Rovida et al., 2020, Bull Earth Eng, doi: 10.1007/s10518-020-00818-y)
Ev..type: "x" indicates that the event is not an earthquake (e.g. explosion, eruption, landslide, ...) (only since May 1st 2012)
Iside.n.: ISIDe id number (only since April 16th 2005)

Details

The original entire HORUS catalog is provided as a single tab separated ascii file: in HORUS_Ita_Catalog.txt a random second decimal digit is added to ML and Md of the INGV bulletin (ISIDe) before computing Mw proxies (Lolli et al., Seism. Res. Lett., 91, 3208-3222, doi: 10.1785/0220200148), in HORUS_Ita_Catalog_o.txt the original ML and Md are used to compute Mw proxies. ETAS.inlabru includes a reformatted version of the data from HORUS_Ita_Catalog.txt as a data.frame, limited to 1960-2019.

The data are provided as they are, no express or implied warranty is given.
