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.
As a result, earthquakes in Iran occur often and are destructive.
The Iranian plateau is subject to most types of tectonic activity, including active folding, faulting and volcanic eruptions. It is well known for its long history of disastrous earthquake activity.
