| Summary: | The earthquakes in Makran have a history of 600 years (1483-2015). The new ventures of
development, urbanization, mining, and exploration for hydrocarbons in Makran region demand recent studies
on seismicity. The major tectonic earthquakes are although infrequent in Makran, but are responsible for
generating tsunami in coastal areas of Pakistan and Iran and have a long tail of aftershocks of shallow to deep
focal depths. The oceanic part of Arabian plate which is underthrusting Eurasian plate (northwards), contributes
a major share in producing seismicity of low magnitude (ML< 4.0). GIS based analyses of earthquake data
suggest that seismicity of Makran is not stationary but has been shifting over local coordinates in the last
century. The other observation is there, may be a chance, that the dates of occurrence of major earthquakes
(magnitude > 6 on Richter scale) has a relation with the rotation of moon (lunar dates) in Makran. |
