Argentina Sleeps Through Massive Quake Powerful but deep earthquake gives country mild shake By Rob Quinn, Newser Staff Posted Jan 1, 2011 8:01 AM CST 2 comments Comments The quake was centered around 100 miles east of Santiago del Estero, capital of the province with the same name. (Wikimedia) (Newser) – Argentinians must be feeling lucky this morning. An earthquake strong enough to have been catastrophic hit the northern part of the country early Saturday, but its epicenter was so deep that towns in the affected area only received a mild shake. The 7.0 magnitude quake struck at a depth of around 350 miles, according to the US Geological Survey. There have been no reports of injuries or damage and a hotel receptionist in the capital of the affected province tells AP that nobody else felt a thing.
