Kerman is prone to natural disasters. A recent flood for example, unearthed the archeological ancient city of Jiroft, in the south of Kerman province. Arg-é Bam on the other hand, the world's largest adobe structure, was destroyed in an earthquake in December 2003. On February 22, 2005, a major earthquake killed hundreds of residents in the town of Zarand and several nearby villages in north Kerman (see 2005 Zarand earthquake).
