TEHRAN (Reuters) - A 5.1 magnitude earthquake jolted Iran's oil-rich southwest on Tuesday, but there were no immediate reports of damage or casualties, official Iranian media said.
The quake occurred at 12:20 a.m. EST near the town of Ghaleh-tal in an eastern part of Khuzestan province and the tremor was felt in the provincial capital Ahvaz and elsewhere, IRNA news agency said.

Khuzestan is the heartland of the oil industry in the world's number four producer but most oil fields lie further west and south from the reported epicenter of the quake.
"We have not received any reports of possible casualties or damage yet," IRNA quoted local official Shapour Rostami as saying.
Natural disaster experts say oil-producing Iran is one of the most earthquake-prone countries in the world because it is criss-crossed by several major faultlines.
