The major goals of the Institute of Earth Sciences at the University of El Salvador (UES) is to promote (1) the advance of the Earth Sciences in the UES higher education program, and (2) natural disaster research activities in El Salvador.<\/p>\n

After El Salvador’ s devastating earthquakes of January 13 and February 13, 2001, the UES asked for the scientific cooperation of the Institute of Technology and Renewable Energy (Canary Islands, Spain) to the Spanish AIDAgency (AECI). The main goal of this Spanish Scientific Cooperation was to provide a multidisciplinary approach for the seismic-volcanic monitoring program in El Salvador by means of establishing a geochemical monitoring program which includes continuous and discrete measurements.<\/p>\n

 UES Geochemical Monitoring Program<\/strong><\/p>\n

\n

(1) Continuous Geochemical Monitoring Network<\/strong>
The Spanish AIDAgency donated to El Salvador Government 6 geochemical monitoring stations to set up a continuos geochemical monitoring network to improve and optimize the seismic-volcanic surveillance at El Salvador. This network consists of: a) 2 continuous monitoring geochemical stations to measure diffuse soil fluxes of carbon dioxide and hydrogen sulfide using accumulation chambers as well as infrared and electrochemical sensors, b) 2 continuous monitoring geochemical stations to measure diffuse soil fluxes of carbon dioxide using accumulation chambers and infrared sensors, and c) 2 continuous monitoring geochemical stations to measure dissolved gas radon concentrations using alpha spectrometry. An additional ITER’ s geochemical station for continuous monitoring of fumarole gas radon is part of the El Salvador Geochemical Monitoring Network.<\/p>\n

These geochemical stations are located in the following volcanic systems:<\/p>\n

    \n
  • Santa Ana-Izalco-Coatepeque volcanic system
    (a) Continuous monitoring of diffuse CO2<\/sub> emission and meteorological parameters at Cerro Pacho, Coatepeque caldera<\/li>\n
  • San Salvador volcano
    (a) Continuous monitoring of diffuse CO2<\/sub> and H2<\/sub> emission and meteorological parameters at Cerro La Hoya, SE flank of San Salvador volcano
    (b) Continuous monitoring of dissolved gas 222<\/sup>Rn in ground waters of Pasaje Verde’s well, southeast flank of San Salvador volcano<\/li>\n
  • San Vicente volcano
    (a) Continuous monitoring of diffuse CO2<\/sub> and H2<\/sub> emission and meteorological parameters at Aguas Agrias, northwest flank of San Vicente volcano<\/li>\n
  • Tecapa volcanic system
    (a) Continuous monitoring of fumarolic gas 222<\/sup>Rn at El Tronadorcito, Berlin Geothermal Field<\/li>\n
  • San Miguel volcano
    (a) Continuous monitoring of diffuse CO2<\/sub> emission and meteorological parameters at the E flank of San Miguel volcano
    (b) Continuous monitoring of dissolved gas 222<\/sup>Rn in ground waters of La Belen’s well, San Miguel City.<\/li>\n<\/ul>\n

    (2) Discrete Geochemical Monitoring Program<\/strong>
