The current studies of cosmic rays are focused on most energetic particles\nentering the atmosphere and producing a single Extensive Air Shower (EAS).\nThere are, however, models predicting that interactions of high energy\nparticles may result in Cosmic-Ray Ensembles (CRE) created far from the Earth.\nThey could be observed as some number of correlated air showers of relatively\nlow energies spread over a large area. The objective of the Cosmic Ray\nExtremely Distributed Observatory (CREDO) is to search for CRE using all\navailable data from different detectors and observatories including even small\nbut numerous detectors spread over large areas.\n Interpretation of such measurements require precise information on properties\nof EAS in a very wide energy spectrum. Low energy EAS are analysed using events\nfrom CORSIKA, the program performing air shower simulations. The primary cosmic\nray particle energy range extends from 1TeV up to 4000TeV. The secondary\nparticles at the ground level are studied in order to obtain their density\nfluctuations and correlations in location. Although the fluctuations observed\nin multiplicity distributions are consistent with random the more detailed\nanalysis reveals that near a selected particle the density of other particles\nis enhanced over that expected in the absence of correlations. The results of\nthis analysis may be useful in further calculations, for example to obtain\nprobability of detection of an EAS without special simulations.\n
