Earthquake catalogs for: A specific earthquake processing workflow for studying long-lived explosive volcanic eruptions with application to the 2008 Okmok eruption
收藏资源简介：
Repository for the seismic catalogs from Garza-Giron et al. (2023a,b). These include the catalog with absolute locations using NonLinLoc (Lomax et al., 2001; Lomax and Curtis, 2001), and the relocated catalogs using hypoDD (Waldhauser and Ellsworth, 2000) and GrowClust (Trugman and Shearer, 2017). The header of the CSV files is as follows: Date (year/month/day), Time (hr:min:sec:msec), Latitude (decimal degrees), Longitude (decimal degrees), Depth (km), Magnitude (Ml calculated for this study), Event_type (VT:vulcano-tectonic;LP:long-period), Number of stations where the event was detected, ID References: Garza‐Giron, R., Brodsky, E.
