    Subject: Hydrogen ; soil gas ; Poás ; Costa Rica
    Description: We report the results of four soil H 2 surveys carried out in 2000–2003 at Poás volcano, Costa Rica, to investigate the soil H 2 distribution and evaluate the diffuse H 2 emission as a potential surveillance tool for Poás volcano. Soil gas H 2 contents showed a wide range of concentration from 0.2 to 7,059 ppmV during the four surveys. Maps of soil gas H 2 based on Sequential Gaussian Simulation showed low H 2 concentration values in the soil atmosphere (
