The seismicity of Iran. The Turshiz (Kashmar) Khorassan earthquake of 25 September, 1903

Abstract

The Turshiz (modern Kashmar), Iran earthquake of the 25th September 1903 occcurred in a semi-desertic region, just south of the Dorimeli fault; it had a magnitude of about 6.5, it was felt within an area of 200,000 square kilometres and it was followed by aftershocks for at least 13 weeks. The earthquake killed about 350 people within an area which extended from Turshiz to the Kavir in the southwest. There is no evidence that the earthquake was associated with faulting, but it did cause a temporary change in the flow of underground water.
