The Bandar Lampungareahas active faults, namely the Panjang-Lampung and Menanga faults, which, based on seismicity data, experienced a relatively large earthquake in 1930 with a magnitude of 6.1 SR at a depth of 35 m centered in Lampung Bay. The results of the calculation of the a-value of the Bandar Lampung city area based on seismicity data from 1930 to 2024 using the Guttenberg-Richter equation and the likelihood function obtained an a-value of 2,251–5,349 and a b-value of 0.290–1,556. Areas with high a-values, b-values, and high seismicity values are in Hurun, Kelapa Rapat, and North of Miwung Hill. Earthquakes in this area generally have a low magnitude (2–3 SR) with shallow depths due to the movement of the Menanga fault. Areas with low a-values and b-values are the areas of Padang Cermin, Lampung Bay, Tarahan, Sebalang, and Kotadalam. In areas with low a-value and b-value, a large earthquake <5 SR with a shallow earthquake source has occurred. The activity of the Panjang-Lampung and Menanga fault caused this earthquake. The results of the seismicity analysis, the Bandar Lampung city and its surroundings show that have relatively low to moderate seismicity values with shallow hypocenter depths and magnitudes of 2–6.1 SR. Although the city of Bandar Lampung and its surroundings have low seismicity values, they have the potential for relatively large and destructive earthquakes.
