Update : What astonishes us more and more at 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
in Salta.

Update : The information in the local press can be called "minimal". Even the San Salvador de Jujuy local press (closest to the epicenter) has only a couple of paragraphs citing the seismic data as the main content.

Update : People living in San Pedro have reported a MMI VI shaking (strong shaking). San Pedro is approx. 60 km from the epicenter. San Pedro has a population of 58,430 people!)

Update : Based on our CATDAT data from November 19, 1973 and the current data, expects a similar kind of damage and NO casualties.

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.
