The U.S. Geological Survey said seven of the earthquakes hit near the Iraqi city of Mandali, which is just 75 miles northeast of the Iraqi capital.
Baldwin, speaking from Golden, Colorado, said that "it's ongoing activity there".
An natural disaster of magnitude 4.7 on the Richter scale was registered in the western part of Iran, the Euro-Mediterranean seismic center reported.
It is unclear how much damage was inflicted by Thursday's quake as the epicenter hit one of the most vulnerable areas in Iran's Kurdish region.
The epicentre, with a depth of 8km, was determined to be at 33.78 degrees latitude and 45.74 degrees longitude.
The quake was felt in several Iranian cities and eight villages were damaged. "So far, no fatalities or injuries have been reported", a local official told Iranian TV.
The region was rocked by a devastating quake last November, in which more than 400 people were killed and around 6,700 injured.
Iran sits on major fault lines and is prone to near-daily earthquakes.
