Extension at the coast of the Makran subduction zone (Iran)
AbstractIn the Makran subduction zone, earthquake focal mechanisms and geodetic data indicate that the deforming prism currently experiences N–S compression. However, palaeostress inversions performed on normal faults observed along the coast reveal local stress components consistent with N‐S extension.

Release of mineral-bound water prior to subduction tied to shallow seismogenic slip off Sumatra [PDF]
Plate-boundary fault rupture during the 2004 Sumatra-Andaman subduction earthquake extended closer to the trench than expected, increasing earthquake and tsunami size.

Stochastic Analysis of Tsunami Hazard of the 1945 Makran Subduction Zone Mw 8.1–8.3 Earthquakes
Historical records of major earthquakes in the northwestern Indian Ocean along the Makran Subduction Zone (MSZ) indicate high potential tsunami hazards for coastal regions of Pakistan, Iran, Oman, and western India.

The 2013 M_w 7.7 Balochistan Earthquake: Seismic Potential of an Accretionary Wedge [PDF]
Great earthquakes rarely occur within active accretionary prisms, despite the intense long‐term deformation associated with the formation of these geologic structures.

Megathrust and accretionary wedge properties and behaviour in the Makran subduction zone [PDF]
We study the Makran subduction zone, along the southern coasts of Iran and Pakistan, to gain insights into the kinematics and dynamics of accretionary prism deformation. By combining techniques from seismology, geodesy and geomorphology, we are able to put constraints on the shape of the subduction interface and the style of strain across the prism. We

Seismic hazard of the western Makran subduction zone: Insight from mechanical modelling and inferred frictional properties [PDF]
Abstract Western Makran is one of the few subduction zones left with a largely unconstrained seismogenic potential. According to the sparse GPS stations, the subduction is accumulating some strain to be released during future earthquakes. To enhance the seismic hazard assessment, we here propose to study the finite deformation of the western Makran ...

Effects of mass waste events on thrust wedges: Analogue experiments and application to the Makran accretionary wedge [PDF]
Olistostromes cover large portions of active thrust wedges like Makran, Gulf of Cadiz, and offshore Borneo. Olistostrome emplacement by submarine mass flow represents an instantaneous and massive mass redistribution that may influence thrust wedge ...

Modeling of contribution of the Late Cretaceous-Miocene sediments of the Makran accretionary wedge to the petrogenesis of basalts from Makran volcanic arc, SE Iran [PDF]
Introduction Makran geological province of SE Iran is an east-west trending mountain range related to the Cretaceous-to-recent subduction of the Indian oceanic lithosphere beneath the southeastern edge of the Eurasian plate (McCall, 1997; Saccani et al.,
