The Large Area Air Shower(LAAS) group has been performing a network observations of extensive air showers(EAS) in Japan. Compact EAS arrays are scattered over 1000 km distances. Each array have been synchronized by using GPS timing modules with accuracy of 1 microsecond. The present status of parallel and simultaneous EASs correlated in multiple EAS arrays is going to be presented in this report.
