Earthquake Report comment :
Very powerful aftershock in the Bio Bio area in Chile. Luckily the epicenter was located in the Pacific Ocean.
The aftershock was this time very shallow at a depth of only 10 km (normally the fatershocks are at a depth of 35 km).
No news of damage or injuries have been reported by the Chile newspapers. The maximum shaking following Oficina Nacional de Emergencia del ministerio del Interior (Onemi) was IV in Conception and a few neighboring villages = light shaking.
QuakeSOS, our earthquake iPhone application has not received incoming alarms. The Mercalli values published by USGS where not experienced on site.
Another earthquake of 4.9 magnitude, creted several alarms.

Most important Earthquake Data:

Magnitude : 5.8

Minor earthquakes are earthquakes without or with little damage risk.  In most cases these earthquakes have a Magnitude smaller than M 5.0 OR earthquakes with an hypocenter (depth) of more than 100 km OR earthquakes up to M 5.9 with an epicenter far away from populated areas.

Chile – M 5.0 – Here we go again ! Living with almost daily aftershocks since February 27

Here we go again. Since August 9 the Chileans were free of relatively strong aftershocks, the longest period since the devastating earthquake from February 27 when a major Magnitude 8.8 earthquake struck the same area, making 577 casualties.
Yesterdays earthquake in neighboring Argentina was a bad sign for the Chileans. That quake was triggered by the same tectonic plates who are trying to settle down since February 27.
A Magnitude 5.0 is mostly heavy in other parts of the world, but in Chile they are used to much more, although M 5.0 brings February 27 back live again.
This earthquake was felt up to Santiago de Chile, the capital.

Testimonies from the field :
Maritza Bravo Valenzuela : very very strong here in talcahuano
Brunilda Jilbert Miranda : We keep a lantern close to us in the event that there will be more aftershocks
Gilbert Arevalo Navarro : DIEGO Y DE QUE COMUNA ERES TU…FUE MUY FUERTE EN STGO EL TEMBLOR QUE TU SENTISTES…YO SOY DE CURICO Y HOY SE AN SENTIDO VARIOS SISMOS, QUE LAS OFICINAS DE SISMOLOGIA DE CHILE NO LOS INFORMA.-PARECE QUE,TENDREMOS QUE PREPARARNOS, COMO DIC…

Diego Henriquez Campos: I am from Maipu and it felt very strong ! (yo soy de maipu y se sinto muy fuerte!)
