SUMMARY - The Kaj Darakht earthquake of 25th May 1923 had a magnitude
of 5.8 and occurred in a densely populated area of Khurasan, near Turbat-i
Haidariyyeh. It affected an area of about 60 square kilometres and caused the
death of about 900 people. The earthquake was felt within a radius of 130
kilometres and its epicentre is located on the Doruneh fault-zone. Originally
calculated and recently re-calculated positions of its epicentre place the event 230
to 530 kilometres from its actual location. A re-examination of this event demonstrates
the need for a critical study of early and more recent instrumental
locations of events in regions of poor coverage from the world seismological
network
