Query: Evaluation of tsunami wave energy generated by earthquakes in the Makran
  subduction zone   The Makran subduction zone, an approximate 1000 km section of the
Eurasian-Arabian plate, is located offshore of Southern Iran and Pakistan. In
1945, the Makran subduction zone (MSZ) generated a tsunamigenic earthquake with
a magnitude of Mw 8.1. The region has also experienced large historical
earthquakes but the data regarding these events are poorly documented.
Therefore, the need to investigate tsunamis in Makran must be taken into
serious consideration. Using hydrodynamic numerical simulation, we evaluate the
tsunami wave energy generated by bottom motion for a tsunamigenic source model
distributed along the full length of the Makran subduction zone. The whole
rupture of the plate boundary is divided into 20 segments with width of order
of 200 km and a co-seismic slip of 10 m but with various lengths. Exchanges
between kinetic and potential components of tsunami wave energy are shown. The
total tsunami wave energy displays only 0.33% of the seismic energy released
from the earthquake source. As a result, for every increase in magnitude by one
unit, the associated tsunami wave energy becomes about 10^3 times greater.
