Speaker information

Gemma Smith, National Oceanography Centre. My PhD is focused on investigating the structure, morphology and fluid distribution of the Makran Accretionary Prism. This subduction zone has been previously understudied by seismic reflection data and currently experiences low seismicity. Its high sediment input (up to 7.5 km) and low taper had lead to previous studies classifying it as a primarily aseismic margin, however the occurrence of a Mw8.1 earthquake in 1945 raises questions about its true seismogenic potential. A major aim of this project is to further understand the behaviour and seismogenic potential of the Makran by placing it in context with other, more extensively studied subduction zones such as Nankai and Cascadia. This will be achieved through the interpretation and integration of over 6000 km of 2D seismic reflection data, in conjunction with multibeam bathymetry and TOBI Sidescan data.
