■ This map shows main
and aftershock
epicenters along with
expected variations in
site acceleration
■ The fault-rupture was
unimodal, propagating
hundreds of kilometers
northwesterly from the
epicenter (star).
■ The data upon which
the USGS modeling is
based do not permit
confident resolution of
the extent of rupture
beyond about 500 km
northwest of the main-
shock epicenter.View entire presentation
