There have been reports of several catastrophes since the Ince earthquake struck.
Iran sits where two large tectonic plates meet and frequent seismic activity is observed.
The country has suffered a number of major disasters in recent decades, including in the ancient city of Bam, which was devastated by a catastrophic earthquake in 2003 that killed at least 31,000 people.
In 1990, a 7.4 magnitude earthquake in northern Iran killed 40,000 people, wounded 300,000 and left half a million homeless, reducing dozens of cities and nearly 2,000 villages to rubble.  Iran has experienced at least three other major earthquakes in recent years – one in 2005 that killed more than 600 people and another in 2012 that left about 300 dead.
In 2017, at least 600 people were killed when a 7.3 earthquake struck Iran's Kermanshah province.
