[Abstract] We have reported a seriese of asearch for the directional analysis of EAS for the Kinki data concerning on the galactic coordinates with energy range between 10^ and 10^eV at sea level. In this report, I will present some basic results abo

[Abstract] Unexpected chaotic features are found in time series of successive air shower (E>3×10^eV) arrival time intervals. Over 99.9 % of air shower arrival time intervals obey the Poisson distribution law representing stochastic behaviors, but th

[Abstract] The fractal dimensionality in time series of air shower arriving time intervals (ASATs) is observed for cosmic rays of energies larger than 3 × 10^ eV . We found 9 cases each composed of 128 ASATs for low fractal dimension (minimum 1.3) a

[Abstract] Extensive air showers have been observed with eight plastic scintillation counters since June 1991. The time structure of the air shower events is confirmed to follow a Poisson distribution. To search for air shower bursts, we have analyze

[Abstract] We have been observing extensive air showers (EAS) energy above O.1PeV at sea level to investigate consecutive events of EAS in short time intervals since 1989. By observing about 215k events with four 0.25m^2 from August 1989 to May 1991,

[Abstract] Using some statistical methods, many investigators have claimed on a basis of the polar angle "cos θ" distribution of neutrinos emitted from SN 1987A that the IMB data seem to be of a non-isotropic distribution, whereas the Kamiokande dat

[Abstract] We have been searched for consecutive events in extensive air showers from mid of summer 1989. Four series of 15 EAS's coming within 10 minutes are found in 210k events of observed EAS. Each lump of the events has extremely small number of
