Relocated seismicity 2000-2015

This relocated catalog has been obtained by Clara Duverger  (Duverger , 2017; Duverger et al., 2018) from double difference relocation (HypoDD) based on both  P and S catalog and cross correlation phases.

Maps of original and relocated earthquakes. (a) Map of selected earthquakes for the relocation
(n~115,000) from 2000 to 2015, recorded by 4 or more stations (triangles) with at least 6 picked phases. These events are plotted at their original location obtained with hypo71. (b) Map of the relocated earthquakes (n~94 000) computed with hypoDD. Dot size is proportional to the magnitude.



Earthquake catalogs and seismicity maps

  • Earthquake catalogs are based on automatic detection and picking. Magnitudes Mw and Ml are also computed automaticaly. Locations are calculated in the 1D velocity model of Rigo et al. (1996) using hypo71 location code. Mw and Ml are calculated using SourceSpec (Satriano, 2020)

  • Format of catalogs is as follows: year, month, day, hour, minute, seconds, latitute, longitude, depth, Mw, Ml, erx, ery, erz, rms, number of P phases, number of S phases, quality (according to hypo71)
  •  Seismicity maps: quality A events (best ones) are in dark red, quality B in red, quality C in orange and quality D (low reliability) in yellow... Size is proportional to seismic moment.
