East Java is located on the junction of two major plates, i.e. Indo-Australian and Eurasian plates which is make East Java pron of earth-quake. Therefore, the study of seismicity in region is needed to reduce the impact of the earthquake. Data that used in this research was the historical data of earthquake by Meteorology, Climatology and Geophysics Agency (BMKG), Karangkates. With range coordinates between 111-114.4 BT East Longitude and 111-114.4 BT South Latitude. There are 211 earthquakes total data were sorted by the depth. And then those data interpreted using ArcGIS software. And these steps result a seismicity distribution map of earth-quake in East Java during 1st January 2003 – 31 Desember 2017. This study is using b value analysis every five year period using the maximum likelihood method. The results of analysis obtained are; in East Java from 2003 to 2017 there were 153 shallow earthquakes happened, with a minimum magnitude of 1.8 SR and a maximum magnitude of 5.6 SR. For the seismicity level in 2013-2017 which is the period of most earth-quake happened, resulting value of b 0.3185. Whereas, for local faults in East Java which were analyzed from the seismicity of maps, we found seven local faults.
