Examination of relocated earthquake hypocenters in the Pamir- Hindu Kush seismic zone using 3-D plots

Reliably relocated earthquake hypocenters in the Pamir-Hindu Kush region for about 1700 earthquakes deeper than 50 km, are examined using 3-D color plots. The hypocenters define an single contorted "S" shaped seismic zone, 700 km long and no more than 30 km wide and with most activity concentrated in the 100-300 km depth range.
