The energy emitted as waves is a very important parameter for understanding the physics of a ruptured earthquake. This energy calculation, however, is difficult and is forged with uncertainty. We use this method to calculate b-value, emitted wave energy and seismic moment energy for 77 earthquakes with magnitude ranging from 2 to 6 and with a depth of 0 to 400 km. The purpose of this research is to analyze seismicity and earthquake energy in Ambon Island and its implications for future earthquakes using b as the precursor. Statistical data for earthquakes that are earthquakes with magnitude ranging from 2 to 9 and with a depth of 0 to 400 km. Furthermore the data is analyzed by Maximum likelyness method using the equation given Utsu and empirical formula from Gutenberg and Richter. The incidence of earthquakes has increased over the last 50 years. After the earthquake in 2005 the increase in the earthquake incidence is increasingly sharp. This is done by the process of achieving the energy that occurs by the plates, which occur after the successive earthquakes to the energy node in three different locations, Location 1. Hatu-Alang, Location 2. Mamala-Morela and Location 3. Wai -Tulehu. The value of the constant b value of earthquakes in Ambon Island is low, ie 0.267 and. These values represent high levels of stress, and most likely large earthquakes will occur again on Ambon Island. Seismic energy in waves from Earthquake Source has the greatest value of 1.12202E + 13 J and the seismic moment energy has the greatest value 2.192805E + 17 J with magnitude 5.5 SR is located to the south of the island precisely the village of Allang. Key words: Magnitude, b-value, Energy seismic, Seismic moment energy.
