ran: The dormant Damavand volcano located north of Tehran began emitting gases and smoke today.

Its last eruption dates back 7,300 years.

The mountain appears on Iranian banknotes and holds a significant place in Persian mythology - it is a symbol of Persian resistance to foreign tyranny.

According to Persian mythology, the smoke coming from the mountain is the breath of the three-headed dragon - Azhi Dahaka - symbolizing that good still triumphs over evil (the dragon is still trapped inside the mountain and cannot escape).
