A strong earthquake in Iran near the border with Pakistan rattled homes as far away as Karachi and Dubai on Tuesday.

The U.S. Geological Survey said the epicenter of the 7.8 magnitude temblor was about 53 miles east-southeast of Khash, Iran.

Though no injuries or deaths were reported as of 7:30 a.m. EDT, the quake was as large as the one that struck portions of northern Pakistan on Oct. 8, 2005, killing 80,000 and leaving millions homeless.

Pakistan’s news agency, which said the quake registered 8.0 on the Richter scale, reported that the tremors were felt in all the country’s largest cities, including the capital, Islamabad. Any measurement above 7.0 is considered a major earthquake.
