According to the U.S. Geological Survey, the strong temblor had a depth of 15 miles or 23 kilometers. Its magnitude was downgraded from 6.8, reports the Associated Press via Yahoo! News.

There were no immediate reports of injuries and major damage to properties, but a few roads and building walls reportedly collapsed sending terrified people to seek safer ground.

The AP report says the city "jiggles like jelly" when there's an earthquake because "much of it sits atop the muddy sediments of drained lake beds."
