Iran is one of the most seismically active countries in the world, being crossed by several major fault lines that cover at least 90% of the country.
The deadliest quake in Iran’s modern history happened in June 1990, devastating many areas in the Northern Province of Gilan and killing around 37,000 people.
In 2003, a magnitude 6.6 earthquake in the Province of Kerman flattened the historic city of Bam, killing more than 26,000 people.
