AN EARTHQUAKE CATALOG FOR ECUADOR The construction of the present unified earthquake catalog, covering 5 centuries is described in the following publication: Beauval C., H. Yepes, P. Palacios, M. Segovia, A. Alvarado, Y. Font, J. Aguilar, L. Troncoso, and S. Vaca (2013). An earthquake catalog for seismic hazard assessment in Ecuador, Bull. Seism. Soc. Am., v. 103, p. 773-786, doi:10.1785/0120120270. The 2013 version of the catalog is now available online (give link). The earthquake catalogs used in these study are the result of years of hard work of seismologists, engineers and technicians, at the Geophysical Institute in Quito, the International Seismological Centre (ISC), the National Earthquake Information Center (NEIC), and at other institutions (see all the sources in Beauval et al. 2013). Please report to us any remark you would have to help improve this catalog, as well as any potential error you would identify. Our aim is to update the catalog regularly. The relocation of 13 years of local seismicity recorded by the Geophysical Institute was performed by Font et al. and is described in this publication: Font, Y., Segovia, M., Vaca, S. and Theunissen, T.: Seismicity patterns along the Ecuadorian subduction zone: new constraints from earthquake location in a 3-D a priori velocity model, Geophysical Journal International, 193(1), 263286, doi:10.1093/gji/ggs083, 2013. The unified catalog includes around 30 historical earthquakes. The study on the derivation of earthquake parameters from historical intensities is detailed in this publication (and completed in the BSSA 2013 paper): Beauval C., H. Yepes, W. Bakun, J. Egred, A. Alvarado and J-C. Singaucho (2010). Locations and magnitudes of historical earthquakes in the Sierra of Ecuador (1587-1996), Geophys. J.

In such case, the publication or the report are indicated in the column srcloc. Details on these references are included in the Beauval et al. BSSA 2010 and 2013 papers. The rest of the sources for location and magnitude could be found in the catalogs of origin.
