Muography consists in observing the differential absorption of muons -- elementary particles produced through cosmic-ray interactions in the Earth atmosphere -- going through the volcano and can attain a spatial resolution of tens of meters. We present two measurements (muographies) of the craters zone of the Stromboli Volcano made using the nuclear emulsion films for particles registration. The first measurement made in 2011 highlights a significant low-density region in the summit part of the edifice. This result was published in Scientific Reports this year. The data acquired by the second measurement done in 2018 using the improved version of the detector, which allow us to reduce the background, are under analysis now.
