Chile 8.8 Mw Earthquake: Impacts on Infrastructure, Limited Deaths Due to Preparedness

Chile well prepared for quakes

By Jonathan Amos
Science correspondent, BBC News

It is not possible to predict the time and magnitude of an earthquake, but certain places on the Earth know they are always at risk from big tremors. Chile is one of those places.
It lies on the "Ring of Fire", the line of frequent quakes and volcanic eruptions that circles virtually the entire Pacific rim.
The magnitude 8.8 event that struck the country at 0634GMT on Saturday occurred at the boundary between the Nazca and South American tectonic plates, just off shore and at a depth of about 35km (20 miles).
The biggest city close by is Concepcion, just over 100km to the south.
Collapsed buildings and widespread disruption will have been unavoidable.
Because the quake occurred below the sea floor, tsunamis were also generated, and alerts were issued not just for the Chilean coast but across the Pacific in general.
