Аnnotation: The results obtained by additional archaeological and archeoseismological studies within the Balandtepa settlement and the Kirkhujra fortress prove once again that the ancient city of Eilatan perished in the I century BC due to a strong earthquake. The city of Pap (Bab) was built no later than the end of the 6th – beginning of the 5th century BC on the site of the settlement of Kyrkhujra, which is located 2 km south of the modern city of Pop, on the right bank of the Syr-Dariya and existed until the 5th century AD. During this time, it destroied several times by floods and covered under mudflow deposits. After each flood, the city was almost completely rebuilt. The city on Kirkhujra was destroyed by the strongest earthquakeat the end of the IV – beginning of the V century BC. After this seismic event, people left the territory of the destroyed city and built a new city for themselves on the Balandtepa monument, located 1 km west of Kirkhujra. Additionally, the information obtained about the unusual location of the debris horizons in the talus – the plume of the destruction of the northern fortress wall of Balandtepa indicates that the wall was destroyed by not one, but three strong earthquakes, which apparently occurred in the late VI – early VII century AD. With each subsequent earthquake, fragments of bricks flew away for longer distances with decreasing height of the wall at each subsequent event. It turns out that each subsequent seismic event was stronger than the previous one. Earthquakes of this sequence can only have a swarm or doublet nature, characteristic of a given territory. This is evidenced by the Pap swarm of 1984 that occurred in this zone, the Gazli earthquakes of 1976 and 1984 that occurred in the zone of the South Tian Shan seismogenic zone. At the same time, the analysis of archaeological materials shows that at the beginning or the first quarter of the VIII century some kind of natural cataclysm occurs. In addition, as a result, the citadel and the residents of shahristan was relocated to rabad. Their places are occupied by artisans who worked here until the last quarter of the VIII century.
