Abstract: Water vapor masers in the NGC7538 molecular cloud were observed with VERA. This region has at least three active regions (IRS1-3,IRS9, and IRS11) in a dense molecular gas core. Each region consists of IR sources, ultra-compact HII regions, CO outflows, high-dense gas cores, water vapor masers, OH masers, methanol masers, etc. We have performed multi epoch observations of water vapor masers in IRS1-3 and IRS11 regions with VERA for more than one year. The purpose of these observations are to determine the detailed distribution of water vapor spots. The detailed distribution of the maser spots are compared with the position and shape of velocity structure of the other activities.
