Also felt in Ardahan, Artvin, Kars and Rize Provinces, Turkey. Two events about three seconds apart. Depth from broadband displacement seismograms, based on second event. FAULT PLANE SOLUTION: P-Waves NP1:Strike=80 Dip=46 Slip=90 NP2:Strike=260 Dip=44 Slip=90 Principal Axes: (T) Plg=89 Azm=350 (P) Plg=1 Azm=170 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2. RADIATED ENERGY No. of sta: 9 Focal mech.
