GNS Science has produced an updated active fault map of the Rotorua District and compiled information that is relevant to active fault hazards. The two main hazards directly related to active faulting In Rotorua District are strong ground shaking and surface deformation. The report presents information and data that is relevant to these two types of hazard. The assessment of ground shaking hazard relies on the characterisation of the earthquake potential of active faults and the transfer of that information (together with seismicity and geodetic information) to probabilistic seismic hazard maps. In the Rotorua District, there are at least 45 major active faults that are capable of generating large earthquakes (Mw 5.5 to 6.9) that will produce strong ground shaking. Individually, these faults rupture with recurrence intervals between 500 and 10,000 years, so the likelihood of ground shaking in the area is high because of the large number of faults. In this report, we provide earthquake data (maximum magnitude, slip rate and recurrence interval) relevant for seismic hazard assessment for at least half of the 45 major active faults. Seismic hazard maps define the probability that a certain level of ground shaking will be exceeded in a certain time interval. These maps are used to evaluate requirements for seismic-resistant design of a site, a region or a country, and are essential for emergency response (combined with building vulnerability) and understanding of other hazards associated with ground shaking (e.g., landsides and liquefaction). Information on probability of exceedance of high levels of ground shaking in the Rotorua area is currently contained in a nationwide seismic hazard map. In the Rotorua District, the level of ground shaking varies from 0.2 to 0.5 g (g or gravitational acceleration = 9.8 m/s2) for 10% probability in the next 10 years, based on results from the 2002 National Seismic Hazard map. The resolution of nationwide maps is too coarse to be used for District level planning. It is recommended that region specific maps are produced to fully understand the level of ground shaking hazard in the area. In addition, the current national map (2002) and the new national map that is close to completion (2010) do not include all the active faults that have been recently (including this report) defined for the Rotorua District. Ground deformation associated with surface fault rupture only occurs along active fault traces. However, Rotorua District has the largest density of active faults in New Zealand, and thus large areas of the district are likely to be affected by surface rupture (ground deformation) hazard. Although faults can often be located accurately (to within a few metres), there is no currently technology to prevent earthquake damage to buildings built across faults (Kerr et al., 2003). For this reason, we recommend the use of the Ministry for the Environment (MfE) guidelines to avoid building across hazardous faults (Kerr et al., 2003).
