A 6.2-magnitude earthquake struck Iran's southeastern province of Kerman on Tuesday, the Iranian seismological center reported, though minimal damage was reported.
Eighteen people were wounded in the quake, which struck in the villages of Hejdak and Ravar in Kerman province, the national emergency service told state broadcaster IRIB.
Officials said old houses were damaged in six villages, and classes at schools and universities were canceled.
The quake struck at 12:13 pm (0843 GMT) with the epicenter around 50 kilometers (30 miles) north of the provincial capital of Kerman and about 800 kilometers from Tehran.
It was measured as magnitude 5.9 by the US Geological Survey and several smaller aftershocks were reported.
This event comes just a day after another quake Monday, which Iranian state media reported at 6.0 and the USGS reported at 5.4, that hit western Iran in the same region where a magnitude 7.3 earthquake killed at least 530 people last month. There have been no reports of deaths or injuries from Monday's quake.
President Hassan Rouhani has highlighted his government's efforts in bringing aid and temporary housing to the victims of last month's quake. Hardline rivals say the government's response was not quick enough or adequate.
Iran sits atop several faultlines, prompting frequent earthquakes.
Iran's worst quake in recent years was a 6.6-magnitude tremor that struck near Bam in 2003, decimating the ancient city and killing at least 31,000 people.
In 1990, a 7.4-magnitude quake in northern Iran killed 40,000 people, injured 300,000 and left half a million homeless, reducing dozens of towns and nearly 2,000 villages to rubble.
Iran has experienced at least two other major disasters in recent years -- one in 2005 that killed more than 600 people and another in 2012 that left some 300 dead.
