Description:
Immediately after the 20th May 2012 Mw 5.9 main shock Emilia earthquake and during the seismic sequence of May-June, 2012, geochemical field investigations were carried out into the epicentral area. This paper provides preliminary soils measurements of CO2 and CH4 performed on widespread liquefactions and ground fractures, occurred after the main shock. Soil gas concentrations and flux measurements on some collapsed caves, already studied in 2008, were repeated again during the seismic sequence of 2012. Observations related to gap forming between buildings and sidewalk, damage of roads, tilting of electricity poles, sand eruption from a well and settlement of ground are also presented.
