(CNN) Two earthquakes struck near a nuclear power plant in southwestern Iran on Wednesday morning, just over a week after another quake hit the region.

The first quake, measuring 4.9 magnitude, struck just before 9.00 a.m. local time in Bushehr province, according to the United States Geological Survey (USGS).

Around 30 minutes later a second quake, this time measuring 4.5 magnitude, struck the same province which runs along the Iranian coastline.

The quake epicenters were within 20 kilometers of the city of Borazjan -- a short distance from the country's Bushehr nuclear power plant.
