A renewed method of macroseismic survey, based on voluntary collaboration through Internet, is running at Istituto Nazionale di Geofisica e Vulcanologia (INGV) since June 2007. The macroseismic questionnaire is addressed to a single non-specialist person; reported effects are statistically analyzed to extrapolate Mercalli-Cancani-Sieberg and European Macroseismic Scale intensity referred to that observer. Maps of macroseismic intensity are displayed online in almost real time and are continuously updated. The aim of the questionnaire is to evaluate seismic effects as felt by the compiler. The final result is the definition of a particular intensity degree, with the evaluation of the associated uncertainty. Results of medium-low magnitude earthquakes are here presented showing the ability of the method in giving fast and interesting results. Effects reported in questionnaires coming from towns are analyzed in deep and assigned intensities are compared with those derived from traditional macroseismic survey, showing the reliability of web based method.
