How to pronounce “valdivia” in English

Earthquakes larger than a magnitude of 8.3 are extremely unlikely at the San Andreas Fault.Compare that to the earthquake that struck Valdivia: it occurred on a fault that dips at a shallow angle.And it broke a section that's at least 1,000 kilometers long and as much as 200 kilometers wide— a much bigger total area— resulting in a magnitude of 9.5.
