example, consideration of all earthquakes that can happen within a radius
of 300 km, evaluated by considering different earthquake sources/types (i.e.
plate-boundary/in-slab subduction earthquakes, crustal earthquakes from
clearly identifi ed faults, and background earthquakes from unidentifi ed
faults). For each earthquake scenario, the probability of occurrence is
assigned based on existing databases of major earthquakes (location, mag-
nitude, depth, faulting mechanism, etc.). In assessing seismic hazard of the
earthquake scenarios, regional ground motion prediction equations (e.g.
Kataoka
et al.
2006), along with appropriate site amplifi cation factors can
be employed. To derive the event-based seismic hazard curve, the identifi ed
