The Seyyeds have decided to move the Capital of Iran from Teheran to somewhere else because of the danger of Earthquakes by 2025.
All of Iran is Earthquake prone. Perhaps Isfahan is least prone, and politically it could be possible that Rafsanjani wants to do this for his own sake. Having a more decentralised Iran, with the cultural, administrative, legislative, and commercial centres, in different cities, on the dutch model seems very sensible, but quite hard to do.
Legislating slower building growth and higher Earthquale standards is less costly. But then tell Rafsanjani that.
