a good state of preservation before the event, suggests that the earthquake was possibly one of the most powerful in the region for approximately 900 years. At a station from the epicenter, the maximum horizontal and vertical accelerations were recorded to be roughly 0.5 g and 0.26 g. A bridge collapsed as a result of the disaster. Water and irrigation systems were severely damaged near the epicenter, and water facilities were demolished in nine villages. Many of the main water pipelines in the affected areas were damaged or destroyed, causing inadequacies in water availability and quality. Surface cracks were observed in Ab Darreh and Changureh, the villages that suffered the heaviest damage, being roughly from the epicenter. The relatively low levels of damage in the towns of Avaj or Ab-e-Garm in comparison to Changureh and Ab Darreh suggest a focus of damage to the northwest of the epicenter due to northwest propagation. In Changureh, only two buildings were left standing and over 120 casualties occurred. Ab Darreh also fared poorly; the disaster destroyed the town's only mosque, toppled 40 homes and killed at least 20 people. North of Avaj, in the village of Esmailabad, survivors recovered 38 corpses, a ninth of the total population, while searching for the missing, feared trapped in the ruins. In another village in the vicinity, Aliabad, two shepherds were the only known survivors. In the small village of Kisse-Jin, roughly 80 corpses were recovered following the rupture. Survivors crying and beating their heads and faces over loved ones were a common sight on Iranian state television. The cost of the damage was estimated at US$91 million. The quake was felt across a wide area, including the provinces of Qazvin, Gilan, Kurdistan, Zanjan, and Hamedan. Of all these, Qazvin was the most heavily damaged, with an unnamed Qazvin official reporting that 177 had died in the province. It was also felt in the capital of Tehran, roughly east of the epicenter, although no serious damage was reported. However, Iranian journalist Borzou Daragahi reported that in Tehran he saw buildings sway and glass objects shatter. Landslides The Bou'in-Zahra earthquake triggered 59 landslides over an area of about . Landslides formed due to the quake included 47 falls and topples, nine slides, and three lateral spreads. The largest of these slides was a rockslide, 150 × 100 m (490 × 330 ft), which occurred southeast of Changureh. Landslides
