Abstract
Seismic deformations in the ruins of the ancient city of Yangi Ahsi (Namangan region of Uzbekistan) have been studied: ruptures with displacement in the ground, collapses over considerable distances, tilts, shifts and rotations of parts of building structures formed as a result of at least two late medieval earthquakes. They are associated with the activation of the North Ferghana flexure-rupture zone. Based on the assessment of the period of recurrence of earthquakes in this area, it is concluded that conditions have now formed here for the occurrence of a seismic event with a magnitude ≥6.
