What is it about?
We have shown the recent tectonic uplift in the N-E of Oman. North Oman is experiencing subduction with subsidence especially in Musandam Peninsula, however, the N-E part of Oman shows pronounced uplift, even a recent one (5 ka Cal BP). Those data and the analysis presented in this work might shed more light in the seismicity of the area. It might be also interesting for the archaeologist since the N-E coast of Oman shows extensive human presence at least from the neolithic period.

Why is it important?
It gives the most recent tectonic activity of N-E Oman. The sea level indicators showed seismic uplift events. Such events have rarely observed in otherwise "quite" or of low seismicity Oman.
Perspectives
More intense sampling (dating) will reveal seismic risk (hazard) for this area. Dating of older marine terraces (higher than 100 m elevation) with cosmogenic radionucleis will give a complete uplift story of the N-E Arabian Peninsula and it will support probably the theory like the forebuldge during the bending of the crust in the subduction zone.
