Update : What astonishes us more and more at Earthquake-Report.com is that NO-ONE talks about the villages at a few km from the epicenter but ONLY about the provincial capitals (big cities of course). Most of the attention should go the the people living in a radius of 20 km from the epicenter location, even more when such a shallow earthquake occurs.

Update : So far no traces of serious damage or injuries. Signs of broken windows in San Salvador de Jujuy.
Mobile networks were out of business for several minutes

Update : James Daniell's CATDAT reports : In November 19, 1973, a 5.9 magnitude earthquake produced damage in the town's eastern provinces of Salta and Jujuy, especially in Santa Clara. No casualties. The estimated peak intensity reached VII degrees on the Modified Mercalli scale and had a magnitude Mb = 5.9 degrees on the Richter scale.
Besides this earthquake there have been many nearby earthquakes without major damage.
