A magnitude 6.0 earthquake hit western Iran on Monday, state media reported.
The center of the quake was near the town of Ezgele, but tremors were also felt in Kermanshah, the largest city in the area.
Iranian state media said the quake was a magnitude 6.0. The U.S. Geological Survey reported it was 5.4. Last month's quake was a magnitude 7.3, leaving more than 400 people dead and thousands more injured.
President Hassan Rouhani highlighted his government's efforts in bringing aid and temporary housing to the victims of last month's quake. Hardline rivals said the government response was not quick enough or adequate.
No reports of deaths or injuries have come in, the governor of Kermanshah province said, according to state media.
Iran is prone to near-daily quakes as it sits on major fault lines.
On Sunday, Iran's official earthquake monitoring center in Kermanshah reported that the province had felt more than 45 4-magnitude aftershocks since last month's destructive earthquake.
In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people.
