Ground motion prediction equations (GMPE) in terms of macroseismic
intensity are a prerequisite for intensity-based shake maps and seismic
hazard assessment and have the advantage of direct relation to earthquake
damage and good data availability also for historical events. In
this study, we derive GMPE for macroseismic intensity for the Campania
region in southern Italy. This region is highly exposed to the seismic
hazard related to the high seismicity with moderate- to large-magnitude
earthquakes in the Appenninic belt. The relations are based on physical
considerations and are easy to implement for the user. The uncertainties
in earthquake source parameters are accounted for through a Monte
Carlo approach and results are compared to those obtained through
a standard regression scheme. One relation takes into account the
finite dimensions of the fault plane and describes the site intensity
as a function of Joyner-Boore distance. Additionally, a relation
describing the intensity as a function of epicentral distance is
derived for implementation in cases where the dimensions of the fault
plane are unknown. The relations are based on an extensive dataset
of macroseismic intensities for large earthquakes in the Campania
region and are valid in the magnitude range Mw = 6.3-7.0 for shallow
crustal earthquakes. Results indicate that the uncertainties in earthquake
source parameters are negligible in comparison to the spread in the
intensity data. The GMPE provide a good overall fit to historical
earthquakes in the region and can provide the intensities for a future
earthquake within 1 intensity unit.
