Anearthquakeaffected several villages in theKerman provinceofIranon February 22, 2005, at05:55:23 local time.The shock measured 6.4 on themoment magnitude scaleand had a maximumMercalli intensityof VIII (Severe).Zarandis located 740 km southeast ofTehran.The maximum recordedpeak ground accelerationwas 0.51gat Shirinrud dam. The United States'National Earthquake Information Centerand the Belgian'Centre for Research on the Epidemiology of Disastersboth show that 612 died and 1,411 were injured in the event.

Damage and casualties[edit]

Four villages, each having around 1,000 inhabitants, were reported completely destroyed, and 30% to 70% of buildings in more than 40 villages were reported damaged. It is estimated that the population of the affected area exceeds 30,000. A great portion of population of several villages are severely affected because of poor condition of buildings. The epicenter of the quake was in a mountainous and sparsely inhabited area. It is believed that the death toll could have been much higher if the quake had stricken a more densely populated area likeBam.

Previous events[edit]
