A series of eight earthquakes has hit the Iran-Iraq border area and rattled Baghdad, apparent aftershocks of a temblor that struck the mountainous region in November and killed over 530 people.

Four people suffered minor injuries in Iran, state television reported.

The US Geological Survey says seven of the quakes struck near the Iraqi city of Mandali, 120km northeast of the Iraqi capital. Mandali is right on the border between the two nations. The eighth hit near Mehran in western Iran, about 90km southeast of Mandali along the sparsely populated Zagros Mountains that divide Iran and Iraq.

All the earthquakes struck within an hour of each other, beginning at 7:59pm (NZ time). Six had a preliminary magnitude of at least 5, while two registered at magnitude 4. Scientists consider earthquakes of magnitude 5 as moderate.

Iranian authorities offered similar figures for the earthquakes on state television. All the information could change as scientists examine the data.

Iranian state television said online that people rushed into the streets as the temblors hit. In Baghdad, people felt a quake shake the Iraqi capital, followed by what felt like aftershocks.

All the earthquakes struck at a depth of 10km, according to the USGS. Earthquakes at magnitude 5 can cause considerable damage. The temblors also all were very shallow, which causes more ground shaking and potential damage, particularly in places without strict building codes.

In November, a major 7.3 magnitude earthquake struck the same region, killing over 530 people and injuring thousands in Iran alone. In Iraq, nine people were killed and 550 were injured, all in the country's northern Kurdish region, according to the United Nations.
