Preliminary Results from DANA Array on the Crustal Structure of the Western Segment of NAF

This study focuses on upper crustal studies such as earthquake locations (especially micro-seismic activity), moment tensor inversions and receiver function analysis. Accurate earthquake locations will eventually lead to high-resolution seismic images of NAF including both the northern and the southern branches in the upper crust.In this study, 722 earthquakes within the time period of 09 May – 17 September 2012 were located. Furthermore, the crustal structure beneath the DANA Array is investigated using receiver functions obtained from the teleseismic recordings from a total of 73 broadband stations. Calculated Moho depth beneath the most of stations is between 33 and 36 km.
