Abstract
Development cooperation projects implemented by the Czech Geological Survey in the area of Central America, focused on the evaluation of natural hazards, took place in the years 1997-2009. They started in Nicaragua (since 1997), continued in El Salvador (since 2003) and then also in Costa Rica (since 2006).
The results of these projects were always handed over to local organizations (INETER, SNET and MINAE) in the form of final reports, and summarized last year in the book by Hradecký et al. 2021. As a supplement to this book, we present here some other findings of projects in El Salvador (from the years 2003-2005) that did not fit into its scope.
They relate to the geology of Quaternary sediments and interesting findings of plant fossils preserved in the Neogene volcanosedimentary complexes.
