. An experimental investigation of multiple muon tracks detected by the MEV (Muography of Etna Volcano) cosmic ray telescope has been carried out during a commissioning phase of the project. The MEV telescope, which is based on three 1×1 m 2 tracking planes segmented into scintillation strips with wavelength fibers and PMT readout, has been installed at an altitude of about 3100m a.s.l. in front of the North-East Etna crater since the summer of 2017. The main aim of this facility is to provide a detailed muography of the interior of the target object. An additional analysis of a first sample of data, taken during a period of approximately two months in 2017 has been undertaken to measure the abundance and topology of nearly horizontal multiple cosmic muons.
