In 1997 , Barka published a paper with Ross Stein and James H. Dieterich of USGS , titled '' " Progressive failure on the North Anatolian Fault since 1939 by earthquake stress triggering " '' , which showed the migration of large earthquakes and , not surprisingly , positive stress accumulation in the Marmara Region . Only two years after this paper was published , the M7 .4 1999 İzmit earthquake hit the Marmara Region , killing more than 17,000 people
