Tools for compiling the Global Earthquake History with the contribution of Paola Albini, Antonio A. Gomez Capera, Mario Locati, Roger M.W. Musson, Andrea Rovida, Daniele Viganò, Massimiliano Stucchi GEM-HGC Global Earthquake History project - Scientific Board, June 2012
Project s Goals! Establishing a distributed, online resource, called Global Archive of Historical Earthquake Studies, where both reports and macroseismic data points (when available) can be uploaded, organized and made available to public (if possible - copyright issues)! Supplying GEM with the best Global parametric Earthquake Catalogue (Mw 7.0) that can be compiled from current resources providing, as far as possible, a link to the background information! Complementing the catalogue entries with comments and, when possible, with earthquake parameters re-assessed from intensity data points and from historical evidence of length of rupture. Epistemic uncertainties will be emphasized rather than hidden, for the benefit of hazard assessments

Central America - New catalogue published: Benito et al., 2012 After a first check, it seems that the catalogue has some gaps, for instance for historical earthquakes of Guatemala We are taking care of comparing it with GLHECAT input catalogues as well as the published studies on Central America
Global Earthquake History 1000-1903, M 7.0 Central America - Retrieved Peraldo & Montero, 1999 (book, 347 pp.) 1717 Sept 29, Guatemala
Global Earthquake History 1000-1903, M 7.0 Central America - Retrieved Peraldo & Montero, 1999 (book, 347 pp.) It contains more than 30 earthquakes with M 7 in the time-span 1516-1898 (note that Benito et al., 2012, do not mention it) Peraldo & Montero informed us (2012) that macroseismic data they collected had been input in a database (around 1999), but unfortunately data in digital format have been lost (!) In the framework of GEM-Global Earthquake History project we aim at reconstructing the database, from scratch (now that we succeeded in retrieving the book)
