In the aftermath of the June 20, 1990 Rudbar earthquake (Mw=7.4)
a local surge of
the Caspian Sea flooded a small portion of its
southwestern corner coastlines. This "surge" which was revealed
recently during a field survey I did in Iran in August 2012, could be
considered a typical example of possible future tsunami
scenarios in the region. As the seismic models for the generation by
this event (through various dislocation patterns) fail to reproduce the
reported run-ups from the fieldwork (along with other important
criteria, also resulted from the 2012 fieldwork), we introduce the
slump source which fits the observed run-ups to areasonable extent (see here).
