  1. Local Earthquake Tomography including secondary phases (Pn, PMP, Sn, SMS, …) Florian Bleibinhaus, FSU Jena Local seismicity at 12° Method

  2. Nocquet (2012)

  3. ZAMG after Willingshofer (2004) Lateral distance of seismicity < ~ 1°

  4. Bleibinhaus and Gebrande (2006) Lateral distance of seismicity < 30 km (circles) Lateral distance of seismicity < 60 km (stars) Projection direction 79° (Strike of the Eastern Alps) ML = 2-3

  5. Base NCA (?) repeating eq

  6. a = 35° a = 21° a = 11° a = 0° Projection of earthquakes (and quarry blasts) from 09/1999 to 10/1999into the profile

  7. Simultaneous inversion for reflector/refractor depth, velocity and hypocenters

  8. East East North South West

  9. Does the IF bound the seismicity of the NCA, or is the IF itself seismically active? • Is the VSB still active? Is its steep dip real or do the eqs belong to separate reflectors? • Is the mid-crustal activity in the Southern Alps localized or distributed along a detachment horizon? • What do the focal mechanisms indicate? • Long recording time (> 2 years) • Dense stations (5 km N-S, 10 km E-W)
