The 2005 Zarand earthquake in Iran occurred on February 22, 2005, at 5:55 AM local time, with a moment magnitude of 6.5. Its epicenter was located near Zarand in Kerman Province, in southeastern Iran. The earthquake caused widespread damage across several regions, with Zarand being the most severely affected city. The Maximum Modified Mercalli Intensity (MMI) reached VIII, indicating intense shaking. The earthquake resulted in significant economic losses, estimated at over $79 million USD, primarily due to building damage and infrastructure destruction. Tragically, it led to at least 400 fatalities and over 1000 injuries. Reports indicate that landslides were triggered by the shaking, although no tsunamis or fires were observed. While there were no major foreshocks, the region experienced several aftershocks, some of which caused additional damage and panic among the affected population.

The folder OpenQuake_gmfs contains the input files required to generate ground motion fields, considering different rupture solutions and conditioning the ground shaking to the recording stations for the event, where available. The figures below present an example of the results, illustrating the median ground motion fields with and without conditioning. These results are based on the rupture and ground motion model that demonstrates the lowest nominal bias. The maximum recorded Peak Ground Acceleration (PGA) was [insert value here], observed at [insert location here]. If no seismic station data were available for the event, the generated ground motion fields are shown without conditioning to recording stations, as illustrated in the figures.
The information collected for the consequences of the event and the corresponding references is available in the Impact folder. When available, information at different geographical levels is provided considering the building damage, economic losses and human impact.
